Grease Guns Buyers Guide

There are a number of grease gun designs, each suited for different purposes. Grease guns with lever and pistol grip designs are inexpensive (around 30 to 40), while battery-powered and pneumatic grease guns can be much more costly (upwards of 200). The latter types of grease guns are easier to operate and suitable for big jobs or frequent use.

Types Of Grease Guns

There are four types of grease guns :

  • Lever : These require two-hand operation via a hand pump and deliver the most grease per stroke of all of the guns. They can be equipped with a wide array of accessories and adapters for optimal use. Lever-action guns are best suited for DIY jobs because of their simple design.
  • Pistol grip : These are operated with one hand and are ideal for close-clearance areas. They typically produce less grease per pump than other guns, but have more precise aim which makes them ideal for automotive use.
  • Cordless : These use rechargeable Lithium-ion batteries for improved portability. They are trigger-operated and deliver a small amount of grease per pull.
  • Pneumatic : These use an external air compressor to deliver a constant stream of grease. Users tend to pair these with bulk-loading equipment for high-volume applications.

Hand-powered grease guns (lever and pistol grip) are less expensive and easy to use for basic applications. However, grease can be particularly hard to pump in cold climates, and operating a grease gun by hand can be tiring. If you use your grease gun in the cold or need to lubricate a great number of joints, it’s worth considering a pneumatic or battery-powered grease gun.

Grease Gun Accessories And Fittings

Many grease guns come with a standard hydraulic connection adapter, but there are several variations that depend on the application. For example, 90-degree adapters are ideal for reaching around corners and bends while needle-end adapters are suited for reaching into tight crevices.

Grease guns either have a fixed or flexible (flex) hose depending on their grease-fitting type, ease of location, and the type of gun. Hard-to-reach locations are better handled with guns that have flexible hoses. Grease guns that require two hands for operation, on the other hand, typically use fixed hoses for improved aim.

A grease fitting. also known as a Zerk or Alemite fitting, is the lubrication point at which a grease connector is attached. The standard fitting is either upright or angled for better application. Button-head fittings are better for applying large volumes of grease and flush-type fittings work best when space is limited for protruding fittings.


A coupler is a useful grease gun accessory that makes it easier to attach a Zerk fitting. The LockNLube coupler helps prevent leaking, ultimately saving time and money. The downside of a coupler is that it can be difficult to position it into hard-to-reach places that only a flexible hose could reach.

What Is A Grease Gun?

A grease gun is a tool used to inject lubricant into mechanical joints and fittings. Machines with moving parts generate friction which can wear down and eventually destroy important parts. Any place where metal rubs against metal needs to be lubricated with grease or oil to reduce wear.

In many cases, machine joints can be difficult to reach. A grease gun usually has a long, flexible hose and a specialized coupler that makes it easy to spread grease directly where it’s needed. It is a tool commonly found in workshops and garages as cars and other heavy machinery need greasing as a part of regular maintenance.

Do You Need A Grease Gun?

Fittings and joints that require regular greasing are becoming less common in modern automobiles. Most new cars have sealed joints that are pre-greased and guaranteed for the lifetime of the part. This means that most people do not need a grease gun as part of their home maintenance toolkit. However, if you need to replace a part, you may need to grease the replacement.

You should get a grease gun if you plan to maintain an older car, farm equipment, or heavy machinery. It’s also a good tool to have for many truck drivers, as trucks still often use grease fittings on tire rods and ball joints. Sometimes a grease gun may be useful for lubricating door hinges.

In this review, we break down our review team’s top picks for the best grease guns on the market and explain what makes them stand out. We’ll help you start your search for a new grease gun if you’re unfamiliar with them or simply need a refresher.

What’s The Best Grease For Grease Guns?

The best grease to use in your grease gun can depend on your project. For mechanical lubrication, there are three common types of grease: all-purpose (AP), multi-purpose (MP), and extreme pressure (EP).

  • AP grease is for everyday use and is appropriate for certain ball joints or squeaky doors.
  • MP greases are more durable, but also more expensive than AP grease. These greases are appropriate for automotive applications.
  • EP grease is the most durable type of grease. This grease is thick and tacky and may contain anti-wear additives such as molybdenum (this type of grease is sometimes called moly-grease).

How to Grease a John Deere Lawnmower, step by step

John Deere is one of the more popular lawnmower brands with good quality products. To keep your mower working well, you need to give it regular maintenance. Regular maintenance ensures that the lawnmower keeps its power, speed, and smoothness. New owners of John Deere and other lawnmower brands are usually not aware of the different maintenance routines that are required. To keep the smoothness of your lawnmower you need to lubricate the moving parts regularly. This improves the wear and tear resistance and makes the machine last longer. Engine oil takes care of the lubrication of internal parts, but axles and wheels and spindles on the deck, etc., have to be greased manually. In this article, we will show you how to grease your John Deere lawnmower.

How to Grease a John Deere Lawnmower:

Two main components of a John Deere mower that require periodic greasing are the front axle and wheels, and the spindles and mower deck. Check and greasing is a simple job. It should be done every 25 hours and should not take more than 30 minutes. Other components that need some greasing include the deck lift pedal, lift arm, rock shaft, lift cylinders, driveshaft, and steering cylinder.

How to grease a John Deere Lawnmower front axle and the front wheels, step by step:

  • Step 1: Park your mower in an appropriate area with the parking brake applied.
  • Step 2: Locate the grease nipple directly underneath the middle of the axle. Put the end of the grease gun in the nipple and pump the handle to grease the axle.
  • Step 3: Locate the grease nipple on the inside of one of the front wheels. Put the end of the grease gun in the nipple and pump the handle to grease the wheel. Repeat the same procedure for the other wheel.
  • Step 4: Also, grease both the wheel shafts. Their grease nipples are located at the front of the shafts, directly beside the tires.

Step by Step Procedure for Greasing a John Deere Lawnmower:

Before we start with the actual process of applying grease, let’s look into the type of grease that should be used. John Deere recommends grease for parts that are involved in high-speed movement and grease for other parts.

The best Grease For High-Speed lawnmower parts:

For components of a John Deere lawnmower that are actively involved in high-speed movement, John Deere recommends the John Deere Multi-purpose SD Polyurea Grease or the John Deere Multi-purpose HD Lithium Complex Grease.

The high-speed parts for which these greases are recommended are:

  • The Mower Spindle
  • Bearings from the rear axle of the mower
  • Universal joints of the mechanical four-wheel driveshaft

The best grease For Other lawnmower parts:

John Deere recommends the John Deere Multi-purpose HD Lithium Complex Grease or John Deere Moly High-Temperature EP Grease for the rock shaft, deck lift cylinders, and deck lift arms and tie rod, etc. These are the components of a John Deere lawnmower that are not directly involved in high-speed operations.

The manufacturer prefers the greases mentioned here. Other general-purpose greases with an NLGI grade 2 rating. over, wet applications require special greases. Consult the user manual or the provider for further info on special greases.

Let’s start with the greasing procedure for a John Deere Lawnmower’s different components with the right grease arranged.

Greasing the John Deere Lawnmower Front Axle and Front Wheels:

Follow the steps given below to grease the front axle and front wheels:

– Step 1: Park the Mower

Park your John Deer mower in an open flat area. Use the parking brakes to ensure that the mower does not start rolling while greasing the different parts. Also, turn the wheels such that they are facing straight ahead.

– Step2: Grease the Front Axle

All components that require greasing have grease nipples where the grease can be added. All you need to do is find the nipple on each component and put the grease in it. The grease nipple of the front axle is located directly underneath its middle section. Put the end of the grease gun in the nipple and pump the gun’s handle until there is pressure in the handle. Then remove the end of the grease gun from the nipple.

– Step 3: Grease the Front Wheels

The grease nipple is located on the inside of each wheel. Locate the nipple, place the end of the grease gun in the nipple, and pump its handle. Remove the grease gun when you feel pressure in the handle. Perform this procedure for both front wheels.

– Step 4: Grease the Front Wheel Shaft

The final step is to grease the nipples located at the front of both wheel shafts located just beside the tires. Put the end of the grease gun in the nipple and pump the handle until grease starts coming out of the bushing. Perform this procedure for both front-wheel shafts.

Greasing the John Deere Lawnmower Mower Deck:

Follow the steps given below to grease the deck of your John Deere lawnmower:

– Step 1: Lower the Mower Deck

Lower the deck of your John Deere mower to the lowest setting.

– Step 2: Grease the Blade Brake Pivot

There are two brake blade pivot nipples, one on the deck’s right side and another on the left side. Spray the two-blade brake pivots with the grease recommended by the manufacturer or with an all-purpose grease.

– Step 3: Grease the Deck Idler Pivot

There is a deck idler pivot to the left of the right-hand blade spindle. Locate this pivot point and spray it with the grease recommended by the manufacturer or an all-purpose grease.

Greasing Other Components from a John Deere Lawnmower:

Follow the guidelines given below to grease other important components of your John Deere lawnmower:

– Mower Lift Arms, Lift Cylinders, and Rockshaft:

Park the mower with the parking brakes applied. Lower the deck completely. Locate the lift arm pivot joint and the rock shaft pivot joint of the front deck. Spray these pivot joints with the John Deere Moly High-Temperature EP grease or the John Deere HD Lithium Complex Grease.

Repeat this procedure for the side deck lift arm pivot joint and lift cylinder pivot joint on both sides of the lawnmower. Use the same grease as mentioned above for these pivot joints too.

– Rear Axle Pivot Point and Rear Tie Rod:

There is a grease fitting/nipple on the left side of the rear axle. Locate this fitting and grease it with the John Deere Moly High-Temperature EP Grease or the John Deere HD Lithium Complex Grease.

Once done with greasing the rear axle pivot point, grease both ends of the rear tie rod with the same greases as mentioned above.

– Drive Shaft:

you should completely lift the mower deck to grease the drive shaft. Once the mower deck is lifted, engage both side deck transport locks. Then grease the front and rear universal joints of the drive shaft with the John Deere Multi-purpose SP Polyurea Grease or the John Deere HD Lithium Complex Grease.

– Hydraulic Steering Cylinder:

The hydraulic steering cylinder is located at the rear of a John Deere lawnmower. Find the steering cylinder and spray both ends with the John Deere Moly High-Temperature EP grease or the John Deere HD Lithium Complex Grease.

Things to Keep in Mind:

If you intend to grease your John Deere lawnmower, keep the following important things in mind:

  • Clean before: Clean the grease fittings/nipple before and after applying the grease with a rug. This is to prevent contamination.
  • Temperature and moisture: The greases recommended by the provider are most effective in a certain range of temperature and moisture. You don’t need to worry too much about the temperature part because the temperature range is, for most grease, pretty wide (-22 to 275 F). Anyway, if you intend to work outside the prescribed ranges, especially for moisture, consult your service provider for special-use lubricants.
  • Use different grease types: Always use the right grease for the right part. A general-purpose grease is generally not recommended for high-speed applications.
  • Check the manual: The grease fittings/nipple may be located at different locations in different models. For the most accurate location of all grease fittings, consult the manufacturer’s manual or your service provider.

When and how often to Grease a Lawnmower:

Greasing is an important maintenance routine. The thin layer of lubricant between moving parts considerably reduces friction. Reduced friction means reduced machine heating, smooth operation, and less wear and tear. Thus regular greasing enhances the performance and service life of a John Deere lawnmower.

We recommend you thoroughly grease your John Deere lawnmower every 25 hours of operation.

Final Remarks:

Proper lubrication is extremely necessary for moving parts of all machines, and your good quality John Deere mower is no exception to this rule. Get the recommended John Deere greases and grease your mower yourself. The greasing procedure is very simple and can be completed in 20 minutes at the most. The guidelines provided in this blog post will help you through the procedure. Regular greasing will ensure that your mower works smoothly and lives longer.

The 7 Best Grease Guns In 2023 Reviews and Buying Guide

Grease gun is a must-have tool for many professionals and home owners who have several power tools. They help to lubricate the parts for smooth running by reducing the friction between the parts. This in turn helps in preventing the machines from wearing out quickly.

Choosing the best grease gun depends on several factors. An ideal option usually distributes the grease accurately and quickly without causing any mess.

Some of the main factors you have to consider while looking for the best grease gun are mentioned below.

  • Pressure Rating : There should be enough pressure for proper dispersion of grease from the grease gun. There are different pressure ratings available for these guns, ranging from 3000 PSI to 10,000 PSI. A gun with low PSI doesn’t apply enough grease for large equipment, whilst a gun with a high PSI might damage the smaller equipment.
  • Grease Loading Types : You can load the grease in any of these three ways – bulking, cartridge, and suction. Among them, the cartridge is the easiest and most expensive way of loading the grease. Suction is quite difficult to load and bulking is a simple yet messy and time-taken process.
  • Hose Length : Applying grease in tight spaces and small corners is quite difficult and requires a flexible hose. So, most grease guns offer a flexible hose of 18-inch length to apply or dispense grease properly on the parts/components of a vehicle or tool. Some grease gun models even come with a longer hose length of around 27-inch or 42-inch. Choose the hose length based on the type of equipment you want to lubricate with these guns.

To help you in selecting the correct grease gun easily and quickly, we have shortlisted some of the Best Grease Guns after having thorough market research on several products.

Buying Guide For The Best Grease Guns

Be it for professional purposes or hobbyists (DIY works), a grease gun is used for different applications like auto maintenance, processing system, agricultural or gardening equipment. The main purpose of using this gun is to lubricate the joint or bearing of the tool/vehicle for improved precision.

Choosing the correct option from various models is always a challenging task, you have to consider various factors like types, loading options, or pressure, which we have explained in this buying guide.

Let’s get into the details of what factors to consider while shopping for a grease gun.


Grease guns are differentiated into three types based on their power source. They are hand lever, battery-operated, or pneumatic powered. Here is an explanation of these types to get a clear idea of which type is most suitable for your needs.

a. Hand Lever : Found mostly in traditional gun models where the grease is emitted via a narrow nozzle to apply grease quickly, and accurately with enough pressure. These days, the modern hand lever models have a mechanism that restricts coming out of grease till enough recommended pressure is applied to it. Thus, it pumps out the grease through the aperture by using a trigger. This gun type won’t need any air hose or power source.

b. Battery-Powered : Powered by a rechargeable battery that let you use them anywhere without any tethered, like on lawnmowers, vehicles, or power tools. Yet the batteries have to be recharged regularly and it is an expensive option compared to hand lever models.

c. Pneumatic : Here pressurized air is sent by an air compressor through an air hose for the proper release of grease via its nozzle. They offer great power and perfect option to use for commercial applications or larger equipment, but not on smaller ones because the air compressor is unable to control the released pressure and thereby ruins your task/work.

For a detailed explanation of grease guns, especially on their types, you can check out our article How to Use Grease Guns.

Pressure Rating

Different levels of power/pressure are required to operate the grease guns. Some are powerful that can easily squeeze a lot of grease at once, while others are underpowered which is harder to push the grease. In general, the pressure output is measured in pounds per square inch (PSI), which ranges from 3000 – 10,000 PSI for grease guns.

Ensure to use the recommended pressure for every application. A grease gun with low PSI doesn’t offer sufficient grease to maintain large equipment, whilst a gun with high PSI might damage small fittings/parts like air tools.

Loading Options

There are three different loading options available for these grease guns – suction, bulking, and cartridge. You should know about them in detail for picking the right option that is suitable for your needs.

a. Suction : It uses a reverse mechanism to fill the barrel. For this, you have to take out the barrel’s head, keep the open end of the barrel into a grease bucket, and then slowly pull the grease into the barrel with the plunger rod (pull back to create suction). Now cover the barrel head to use the gun.

b. Bulking : Though it seems a simple process, yet a messy and time-taken process to reload the grease into a grease gun. All you need is to manually load the grease with a scoop or putty knife into the barrel. It is ideal for hand-lever models having small barrels.

c. Cartridges : The easiest, and cleanest way to fill grease into the gun, yet expensive as well. You have to remove the old cartridge from the gun’s barrel and simply keep the new one to get your work done.

Action Types

The main purpose of using a grease gun will matter a lot when choosing them. For instance, if you want to use it for oiling the car undersides or simply to grease power tool components or something multifunctional. We can’t use a single type of grease gun to perform a variety of tasks. Hence check several models and select the apt model that works well for your project/task.

Hose Length

It is essential to know the hose length of a grease gun before investing in them. If you are familiar with lubricating different machines or power tools, then you must know that grease has to be applied in various tight spaces and difficult corners. While this should not be an issue if you are applying it with your hands, using a large grease gun in tight spaces is a different one.

So, to overcome this issue, grease guns offer a flexible hose at the front. But not all grease guns have the same hose while most of them offer an 18-inch hose length, others might use a longer 27-inch or even a 42-inch long hose for ease of use/access to your fittings.


We all are aware that grease comes out via a narrow nozzle after applying some pressure on the gun. In case, if you are using a model having a low-quality head, plunger, or seal, then it results in leakage of grease that produces a lot of mess and minimizes the pressure in the gun, which results in the not efficient working of the grease gun.

To get rid of these leaks, you have to double-check the model and pick the one offering hardened plungers, sturdy metal barrels, top-quality seals, and clean, tight-fitting threads of barrel heads.

Barrel Size

The size of the barrel matters based on the purpose of using the grease gun. However, a large barrel size is the best option when you want to deposit more grease in less time. Alternatively, a small barrel is ideal to use when you need to have small specialty applications. So, choose the barrel size depending on the intended use of your grease gun.

One-Handed Design

Usually, most grease guns are built to use single-handed, while some lever handle gun models need to use both hands for accuracy and speed in their performance. So, we suggest you choose an ergonomically designed gun model offering light form factors and having rubber grips and handles. This will minimize any accidental drops.

Sizes (Standard Vs Mini)

The size of grease guns can be differentiated in two ways – standard and mini, and most people prefer to use them based on their profession or task requirement. Here the standard size options come with a 14-ounce canister of grease that is quite helpful for professionals, whilst a smaller gun with a 3-ounce grease tube is useful for hobbyists. Even though each size has its own set of benefits, yet the mini grease guns are designed to be cheaper compared to standard size gun models.


For appropriate delivery of grease, it is essential to check the nozzle of the grease gun before making its purchase. In general, there are two nozzle styles available for grease guns – the short, straight nozzle and flexible metal nozzle. However, the flexible nozzle comes in various lengths making it an ideal option to use precisely in hard-to-reach areas and most suitable to perform various tasks. While short and straight nozzles are good at applying gear on the spot with short lengths.


A grease gun with high quality will aid in smoother operation because it makes the working parts work freely without much friction. So, select a grease gun that is quite easy to use and offers an accurate and even dispense of grease via a bleeder valve by preventing air s.


Several grease guns are made from durable materials like metal that help to sustain the pressure that built up while using these grease guns. Whilst gun models made of low-quality materials like plastic components are more prone to breakage and regular wear.

Pressure and Accuracy

Without applying pressure, you can’t pump or add grease properly from the gun to the parts. So, pressure is a crucial factor to consider before investing in these guns. Usually, a gun with higher pressure will quickly and easily control larger areas, whereas lower pressure guns target specific areas accurately. If you are dealing with a variety of projects, then go with a grease gun featuring variable pressure. Pneumatic models come with toggles to change/alter the pressure.

Coming to its accuracy, it is quite more important while dealing with professional-grade tasks rather than household (DIY) tasks. Ensure to choose the model having a narrow stream that let you identify the apt spot required to grease and thereby perform your greasing work.

We suggest you get a grease gun with a hose attached, which let you easily get into hard-to-reach spots, and offers some flexibility to aim at the spot where you want to grease on the specific parts/fittings.

The safety features are essential to consider before buying a grease gun, as it should not harm yourself or the surrounding people (especially kids and pets). Models offer more or fewer safety features, in which you have to pick the one offering safety features required for your proper working on the projects.

Some safety mechanisms include a lock mechanism (tool won’t get activated without unlocking), non-marring tips (protect from self-damage), lock, coupler, and loop. Check them and choose the best model while buying the grease gun.


These days, most contemporary grease guns offer various accessories, which include a number of couplers, lengthy and flexible hoses, nozzles, and other related equipment. Some grease gun models come with pre-lubricated, which allows you to use them instantly after you take off from the pack.


The built quality and the construction material of any product will determine its durability. Usually, most models are constructed with steel, yet the steel quality varies a lot. Some are strong and durable, while others are dented and break easily.

Any product made of high-quality and durable materials costs a bit expensive. However, it is not a fact, that some expensive models won’t be durable at all. So, we suggest you check the material, and online reviews on the product before making its purchase.

Ease of Use

Always prefer to select a grease gun that is easy and straightforward to use, in such a way that has to fire on the spot where it is placed. Yet won’t be a complicated one, which ruins your project and puts you under extra stress and tension for proper completion of the project. Usually, hand-lever, battery-powered, and pneumatic are the three main types of grease guns.

  • With its easy-to-control and use feature, a hand-lever model is an ideal option for beginners (novice). It let you adjust the grease flow and pressure through the nozzle.
  • Without being tethered, these cordless models are controlled with a trigger that can be the best option for individuals having substantial experience. It is heavier and a bit harder/difficult to use.
  • Attached to an air compressor, these pneumatic models are harder to move around the workplace or garage. Yet easy to control the flow of grease.


As an operator, you have to lift, hold, direct, and control the grease gun for its proper flow in the specific area of application. So, you have to check the model with an ergonomic handle design for a comfortable holding and operation.

This ergonomics helps a lot in enhancing your efficiency, which let you control the gun and operate it quickly and accurately. Hence, we suggest you go with a product built with lightweight materials, cushioned grips, and several nozzle options to get relief from hand fatigue, even while using it for a longer time.


The price range of these grease guns will vary a lot based on their features, types, warranty, and built quality. The price of simple hand-operated units will range from less than 20 and can be up to a few hundred dollars for pneumatic, cordless, or sophisticated powered models. You can choose the best model that comes within your budget range and is best suitable for your requirements.


Buying a heavy-duty or industrial tool like a grease gun, you would expect it to last for a long time without any issues. For this, you have to check the build quality and warranty of a given grease gun. You will find that most guns out there come with a 1-year long warranty, with a few of them offering longer warranty periods.

Yet it is difficult to find the models offering a lifetime warranty. The longer the warranty, the better you can utilize the tool, as it comes with excellent build quality that protects the gun from getting any damage.

Benefits of Using a Grease Gun

Knowing the benefits you can grab by using a grease gun before investing in them is essential. Here are a few mentioned below.

Speed and Accuracy : A grease gun is an excellent tool that let you grease the entire underside of a car within a few minutes quickly and accurately.

Longevity : If you are a frequent grease user (mechanic or hobbyist) then having a grease gun is quite useful to perform your tasks easily. Besides proper lubrication for the smooth running of vehicles or power tools for a long time, the grease gun stands the test of time, if maintained perfectly.

Prevents Wastage : Being an efficient delivery option for grease, lube, or oil, the grease gun provides the essential lubrication required for the smooth working of a tool or vehicle. You can measure the dispense amount per stroke which allows you to prevent waste from any overflowing product.

Effective Saturation : Usually, a grease delivery system sprays the grease onto the general area of a component. Whereas, the grease gun will let you deliver this grease onto the specific area with high precision. This results in proper saturation of the required parts/fittings.

Saves your Money : A simple thing is that well-lubricated parts/components will last longer and won’t let you invest your money in their replacements/repairs. So, a grease gun prevents spending extra money on parts.

Tips for Using the Grease Guns

Take a look at the following tips that are quite helpful for the proper filling of grease and the usage of the grease gun.

  • Don’t add or introduce foreign particles and other contaminants while loading the grease pump with grease, as it may result in damaging the overall machinery.
  • It is necessary to check the grease dispensing nozzle to know whether it is clean before pumping grease into the gun. For this, squeeze a little bit of grease through the nozzle and wipe it off with a clean cloth. Now fill the grease to lubricate any part or fittings without any dirt/contamination.
  • Since grease is available in different formulations and weights, ensure that you are using/applying the correct quantity and type of grease for every part of the specific machinery or components.
  • Clean the fitting/parts to get rid of any built-up grime on them before applying new grease to those parts. This will help to remove debris and aids in a smooth application for their proper working.
  • If using a pressurized grease gun, then store it properly in a horizontal position without pressurizing it while not using it to avoid leakage of oil out of the grease.

What Signs do we Notice for Under Greasing and Over Greasing?

Even though lubrication is a compulsory thing, grease has to be applied accurately (without over or under the standard amount prescribed for the parts). Over- and under-greasing lead to malfunctions of the machinery. Hence, you have to be aware of the amount of grease applied to the parts/components.

Using/applying too much grease or pressure will result in over-greasing. This might lead to the risk of debris getting on your machinery components, which in turn results in grinding, jamming, and damaging its seals. So, whenever you found excess debris on the components, then simply it is a sign of used over-grease. To prevent this from happening, you have to use the gun featuring pressure gauges and automatic shut off.

Over-greasing is a bit tricky and hard to observe, while under-greasing is one of the easiest ways to discover. If not using enough grease on the components, then they are unable to move freely and might fail their function. Also, you can observe other under-greasing signs such as friction, excessive heat, and strange noises.

Frequently Asked Questions

Suction, bulk, and cartridge are three main ways to load the grease gun.Use a putty knife or small scoop in the bulking process to put new grease into the barrel.Insert a new grease cartridge by removing the old one whenever it gets empty.The suction way of loading involves a bit more process. Take out the barrel head of the grease gun, and place its open end in a grease bucket. Then pull back on the plunger rod by pushing the barrel down into the grease to load the grease into the gun.

Applying too less (under the basic level) or too much (over greasing) might result in causing significant problems to the machinery and might lead to its overall failure. So, we suggest you apply the required amount of grease guns to your machines and tools to enhance their proper working.

Usually, a free-flowing, good-quality lubricant is the best way to use with a grease gun. Yet ensure that not mix different types of grease to prevent damage to your machinery equipment.

Use grease guns to lubricate various parts on the chassis of the vehicle and running gear. Chassis lubrication is a common thing included in automotive service visits till before the 1980s. Some parts such as kingpins, bearings, and bushings are sealed properly and thereby require less care.While grease guns inject lubricants into certain components like universal joints, wheel bearing, or steering joints (the parts where regular maintenance and checkup is required for the proper functioning of the equipment). Thus, it helps those parts to move freely and deter them from the damage of regular wear and tear.

To inject the grease into the lubrication system of machinery, the grease gun has to connect with its nipple. For this, you have to use this coupler, an attachment (or accessory) of a grease gun used for proper filling of grease.

The list of products that we have mentioned above is from the best manufacturers. DeWALT serves the best in this industry, and others include Lumax, Bravex, Steinbrucke, Lincoln, and GreaseTek.

Usually, the grease guns are designed mostly to use with heavy lubricants which are not free-flowing and have to apply some pressure for their proper flow.

The general-purpose grease available in the market is enough to use for cars, yet some parts such as wheel bearings need a specific type of grease but not a general-use grease. We suggest you refer to the manual to know which type of grease is applicable for your car.

9. Does the zerk fittings of grease the same? Does the grease nipples are all of the same sizes?

Usually, yes, they are similar. But some heavy-duty commercial equipment and grease fittings are the same or similar, in which any grease gun should work well on them.

The amount of pressure to be applied will vary from one model to another. They put out from 0 – 15000 PSI. However, most bearing seals are unable to handle the pressure of more than 500 PSI. This means excess levels will be wasted power in most cases.

Based on the specific type of your vehicle, the frequency to use and the amount of the grease gun will differ. Generally, a hand lever or pneumatic grease gun will perfectly fit on occasional use. While battery-powered grease gun is an ideal option to use for making things easier.

You have to store the cartridge tube in an upright position to prevent separation and bleed. After loading the cartridge into the grease gun, you have to store them in such a way that depressurizes the gun, wipe them off with a clean cloth to remove contaminants, and finally store them in a horizontal position.

The output of grease amount will vary from one model to another, which range from 0.8 to 3 grams per stroke. You can calibrate to adjust the dispensing amount of grease for its proper lubrication.


If you work on a lot of large scale machines, then you must know that regularly lubricating them is quite important. Even though you can do this by your hand, that can be highly time-consuming. Thankfully, applying grease is quite easy, especially if you are using a tool like a grease gun. Here in this article, we have already mentioned the best grease guns up above. All of them have been provided along with their important details like major features and options.

The Best Grease Guns to Buy

We all know that it can get very painful very fast without the proper lubrication. You will sit there crying over the fact that your super expensive machinery has stopped working or broken only after a few uses.

A good grease gun is essential to have around. Those of you who rely on your tools, large equipment, or machinery to make a living know the importance of keeping everything lubed up. Almost all machinery and some tools need to be greased every once in a while, if not daily.

It will keep your machinery or tools running like new and prevent accidents. No matter how big or small the job, a good reliable grease gun is a must.

Why do I need a Grease Gun?

Some people grab their old rusty can of WD40 and spray the crap out of any moving part on their equipment or machinery and think that is enough to keep them lubricated and running like new. You’d be surprised to know how many people I’ve seen spray some oil from a can onto their landscaping equipment and then blame the quality of the equipment when something breaks.

Some moving parts on specific tools need to be sprayed with oil, but for example, your lawn mower’s front wheel bearings might need to be greased with a grease gun to lubricate them properly. Spraying some old oil won’t do the job. Sometimes having a mini grease gun around can prolong the life of your equipment.

What is a Grease Gun?

A grease gun is used to apply a certain amount of grease to a specific location through grease fittings via pressure. There are hundreds of grease guns, connectors, adapters, and accessories out there, so make sure you know what the purpose of the grease gun will be.

There’s no need to spend hundreds of dollars on a grease gun and accessories that will only be used on your lawn mower once a month. On the other hand, if you own or operate heavy, expensive machinery and depend on them to make a living, I recommend purchasing a much better one along with some extra accessories.

Types of Grease Guns

There are four types of grease guns: lever, pistol grip, pneumatic, and electric. Each one has its pros and cons; the one you choose will depend on the jobs you plan to tackle.

Lever Grease Gun

best, grease, guns, lawn, mower

A lever grease gun has to be operated with both hands and is excellent for those needing to pump a large amount of grease because they deliver the most grease per stroke. You will have one hand holding the tube/body of the grease gun and the other pumping the lever. They are great for using on large machinery needing lots of grease but doing lots of greasing with it can tire out your arms.

This type of grease gun was prevalent about 20 years ago and is still quite commonly used today. Most are pretty cheap and found almost anywhere. They can get very messy when changing the tubes, and sometimes they leak grease from the bottom, wasting a good amount of grease.

If going for one of these types of grease guns, go for one with a flexible hose instead of a fixed one. Holding the gun steady while pumping grease with both hands can be very difficult. The flex hose will allow some movement without damaging any of the fittings.

Pistol Grip Grease Gun

best, grease, guns, lawn, mower

The pistol grip grease gun can typically be used with one hand and is fairly straightforward to operate. They do not pump as much grease as the lever one, so they’re ideal for smaller jobs like mowers and other small equipment around the home or shop.

Another reason to stick with a small job using these is that they can tire out your hands very quickly. Most are also cheap and can be found almost anywhere as well.

I suggest getting one of these for those who want to keep a grease gun on hand and for those who will be using it for smaller greasing tasks. If you’re in the market for a mini grease gun or want the best mini grease gun, then it will most likely be a pistol grip grease gun.

Pneumatic Grease Gun

best, grease, guns, lawn, mower

Pneumatic grease guns are perfect for greasing in big shops where you can easily access an airline, and they can also be carried around along with a small compressor. These grease guns, like the electric ones, are ideal when doing a lot of greasing.

They are not the best because of the fact that you have to deal with a long air hose attached to it that can sometimes get in the way. Also, they aren’t as portable as any of the other grease guns because you have to carry a compressor or gas tank along with you.

Some pneumatic grease gun models can be used with an inline greaser, meaning that a hose pulls grease from a drum instead of grease cartridges. These are also a little pricey but not the most expensive out of the four.

Electric Grease Gun

best, grease, guns, lawn, mower

Electric grease guns are very popular nowadays because they take a lot of the work out when it comes to greasing. They are great for when you have a lot of greasing to do.

They are easy to carry around but tend to be much heavier and a little bigger than the other grease guns. They are also available in many big stores but are much more expensive than the other three grease guns.

These guns are best for those who need to keep their large, heavy equipment up and running like new and for those who want to get greasing tasks done quickly. With this grease gun, you risk an electrical component being damaged and leaving you with no grease gun, so keep that in mind if working in harsh conditions.

Our Top Grease Gun Picks:

I have compiled a small list of the best grease guns you can buy now. Each one earned its place because of a few factors. Their durability, versatility, PSI, flow rate, and brand reputation.

Once you have determined the reason for buying a grease gun, research and read plenty of reviews on the specific gun you choose. Make sure you learn how to grease specific machines or equipment properly because if not greased properly, it can lead to damaged seals and even under-greasing.

Also, buy any extra connectors or different types of hoses for your specific job. I suggest you purchase a LocknLube Grease Gun Coupler if you plan on doing a ton of greasing.

Milwaukee M18 2-Speed Cordless Grease Gun

Why We Picked It

If you can only own one grease gun to tackle all your jobs, this is the best grease gun to buy. I have owned many Milwaukee products, and they never disappoint. Milwaukee is one of the best tool manufacturers out there.
