How Much Gas Does a Lawn Mower Use? (Guide 2023)

You have a gasoline lawn mower at home, and now you’re wondering how much gas does a lawn mower use? Honestly, it’s the best decision you’ve made; the way gas are increasing, you should know how much you’re investing in your lawn mower.

The total amount of gas you’re using depends on the type of lawnmower. For example, a push lawnmower tank can hold up to 1 quart of gas and riding lawn mowers 2 – 4 gallons. While zero-turn lawn mower capacity is high, around 2 to a maximum of 6 gallons.

In short, it all depends on what machine you’ve. To understand why it depends on the machine, you have to be with us till the end of this article.

Why Is the Capacity of Gas Tanks Different In All Lawnmowers?

Every lawn mower is different not only in terms of type, efficiency, and design but also in size. Push lawn mowers are comparatively small to zero-turn lawn mowers. So there’s no way a big tank of a zero-turn lawn mower can fit into it, and that’s the reason.

All lawnmowers consist of parts that are compatible with its design. If the design is big, like a riding lawnmower, the fuel tank will be bigger in size. At the same time, if it’s about the push lawn mower, the gasoline tank would be small.

How Much Gas Do We Use In Different Types of Lawnmowers?

Before we go further, we want to e important piece of information. Gas isn’t used as fuel in all types of lawnmowers. Nowadays, you can find various types of mowers which work with electricity, like robotic mowers or electric riding lawn mowers.

Here we’ll only discuss the three main types of lawnmowers that work with gasoline. We’ll share an average point of view about how much gas each type of lawn mower uses. Let’s get into the details of it!

Push Lawn Mowers

Push lawn mowers are an excellent choice for those with small to medium-sized yards who prefer budget-friendly mowing options. They’re generally small in size compared to the other types, like riding lawn mowers; that’s why their tank capacity is also low.

lawn, mower, fuel, consumption

According to our research, the tank of push lawnmowers has a capacity of 1 quart, which is nearly equal to 1 liter. With this fuel, you can easily mow your home lawn or a small garden without any issues.

Riding Lawn Mowers

Riding lawn mowers is the second most famous type of lawnmower, and it’s widely used worldwide. Riding mowers use gasoline or electricity to turn the blades that chop up grass clippings and make your lawn beautiful.

These mowers are a little bit heavier not only in size but also in terms of engine and tank size. In general, the small riding lawn mowers tank capacity is around two gallons. However, if the size of the riding lawnmower is large, it can increase up to 3 to 4 gallons.

Zero-Turn Lawn Mower

The zero-turn lawn mowers are more powerful than riding lawn mowers. With its independently-controlled rear wheels, it can pivot around on its own axis, resulting in extremely tight turns and an ability to navigate hard-to-reach areas with ease.

This lawnmower makes cutting grass a breeze and drastically reduces the time required to complete mowing tasks. With all of these features, it can hold up to an average of 2 gallons and a maximum of up to 5 or 6 gallons.

Gas vs Battery Lawn Mower. Which is better?

How Much Gas Should You Use In Lawn Mowers?

The amount of gas you can add to your lawnmower depends on the capacity. Therefore, we suggest you go and check the tank and understand how much it can hold up too. If you’re not an expert in it, then it’s better to take help from someone.

After determining the capacity, you can fill as much as you want within the limit. For example, in case you own a riding lawn mower with a capacity of 2 – 4 gallons. You’re free to add up to 4 gallons of gasoline but don’t exceed the limit; it can be dangerous and a waste of money.

Frequently Asked Questions (FAQs)

Is it safe to use fuel stabilizers in lawn mowers?

Yes, it’s completely safe to use fuel stabilizers in lawnmowers. These fuel stabilizers are specifically made to protect the fuel and extend its life. Therefore, there’s no way they’ll harm the mower.

Which is better: electric or gas lawn mowers?

The type that suits you is better; it can be an electric lawnmower or even a gas lawnmower. If you think purchasing gasoline frequently isn’t an ideal situation, then the electric lawnmower is best. You can charge it at home and use it easily.

What’s the best gas fuel for lawn mowers?

You need to find fuel that’s unleaded and has a rating of OCTA 87. This OCTA (octan) 87 rating shows us the quality, or in other words, fuel ability to perform.


It’s important to know how much gas does a lawn mower uses so you can be prepared to fill it up when necessary. But there’s one other important thing that people mainly forget. Apart from keeping the tank full, you should worry about whether you’re using quality fuel or not.

If it’s not quality fuel and OCTA 87 rated, you’re not saving money but creating a lot of issues for the future. You may have to spend a large amount of money on lawnmower maintenance. So, use premium fuel and make sure to do proper maintenance of the mower from time to time.

Electric vs Conventional Lawn Mower Environmental and Economic Impacts

Learn how the use of electric lawn care equipment can have a positive effect on the environment and the economy through decreased fossil fuel use; reduction in C02 emissions; potential for increased use of renewable energy; lower noise output; cost of electrivity vs gas/diesel; low maintenance and repair costs; and the support of local economies.

Decreased Fossil Fuel Use

According to the US Department of Transportation, Vermont consumes 5,453,000 total gallons of gasoline per year for lawn and garden care (the nationwide total is 2,982,755,000 gallons). Traditional commercial gas/diesel mowers typically burn 1 to 2 gallons of gas or diesel per hour. Therefore, for every commercial gas/diesel lawn mower that’s replaced with an electric mower in the New England region, fossil fuel use can be reduced by approximately 1,440 to 1,920 gallons per year (assuming 6 to 8 hours/day, 5 days/week, 24 weeks/year).

lawn, mower, fuel, consumption

Additionally, depending on the type and horsepower rating of mowers used by homeowners mowing 1 to 2 hours a week (for 24 weeks), anywhere from 5 to over 50 gallons of gas or diesel could be saved per year.

CO2 Reduction

Since every gallon of gas/diesel burned emits an average of about 22 lbs. of CO2 (includes the carbon in the gas/diesel plus the oxygen used during combustion) and because electric mowers have zero CO2 emissions, for every commercial gas/diesel lawn mower that’s replaced with an electric mower in the New England region, CO2 emissions could be reduced by approximately 31,680 to 42,240 lbs (approx. 16 to 21 tons), less the amount of C02 emissions generated by the production of the electricity used, which increasingly is being generated from renewable sources such as sun, wind, and hydro. Therefore, for every 100 commercial gas/diesel lawn mowers that are replaced with electric mowers in

Increased Use of Renewable Energy

With ever-expanding solar and wind energy capacity in New England, there’s an ever-increasing potential for the electricity used to recharge batteries to come from renewable sources.

Low Noise

Battery-electric lawn care equipment produces significantly less noise compared to conventional gas-powered equipment which improves the quality of life in our communities. For more information about how the issue of noise is being addressed on a local and national level, visit Quiet Communities.

Electricity vs Gas/Diesel Costs

The electricity needed to operate battery-electric lawn care equipment costs a fraction of the cost of gas or diesel.

Lower Maintenance Costs

Gas/diesel mowers require engine servicing that increases operating their life-cycle costs. E-mowers need NO maintenance aside from normal blade sharpening and cleaning of accumulated grass from around the blades.

Lower Repair Costs

Gas/diesel mowers have hundreds of moving parts, and these inevitably wear out and need replacement. These repairs are time consuming and increase life-cycle costs. Conversely, E-mowers have very few moving parts and are designed to operate for thousands of hours with minimal or NO needed repairs.

Support of Local Economies

For every dollar not spent on imported gas and diesel fuel, more dollars remain to support New England’s local economy.

Lawn mower fuel consumption

The zero-turn mower design with its high capacity and swift manoeuvrability originates from typical commercial use. Our zero-turn mowers for landowners are engineered alongside our commercial models. This means they can handle heavy-duty mowing tasks on large areas efficiently, quickly and easily.

Are you a professional or homeowner?

When deciding on a new zero-turn mower the most important factor is the size of the area that you will cut.

Our zero-turn mowers for homeowners are generally smaller, which makes them take up less space when parked and they can also cut smaller passages in the garden. The biggest of the home or landowner models can handle 2.8 acres per hour.

If you are looking for a new zero-turn mower for professional use, we have a wide range with powerful engines and bigger fuel tanks. The professional models are faster and can handle bigger areas. up to 7 acres per hour.


Propane is a great way to lower emissions, fuel costs and possibly get tax benefits. But there are a lot of other benefits to propane as well. A propane engine generally needs fewer repairs since propane doesn’t go stale. If you are looking for full day operation you should also consider getting the optional dual 33lb tanks that hold 14 gallons of fuel.

Which petrol FR lawn mower?

Which petrol is suitable for lawn mowers? Any normal petrol from the gas station is suitable. whether E 10 or conventional fuel.

What do I fill up for a lawnmower?

Petrol from the service station for four-stroke lawn mowers. With four-stroke engines, you can fill up with normal gas station petrol. However, you don’t have to use the more expensive Super 98 here; Super 95 is perfectly adequate.

Can you fill up lawn mowers with E10?

There is a great deal of uncertainty at the filling stations: Many drivers do not know whether the new environmentally friendly fuel E10 will fit their vehicle. They fear for the health of their engine. There is a lack of reliable information, which greatly upsets consumers.

  • After all, engines that cannot handle E10 can suffer major damage: corrosion, pitted seals and leaking hoses.
  • For the time being, customers prefer to use conventional fuel.
  • By the beginning of spring at the latest, garden owners will also be asking themselves whether their petrol-powered lawnmowers, hedge trimmers or shredders can use the new fuel with a ten percent ethanol content.

Yes they may! Definitely the newer generation engines. If you are unsure whether your lawn mower is one of them, you should do what drivers are advised to do: ask the manufacturer.

What oil goes in a 4-stroke lawnmower?

Lawn mower oil SAE 30 and other key data. First and foremost, it is worth taking a look at the lawn mower’s user manual to determine the right engine oil for the lawn mower. Basically, it is recommended to use an engine oil with the viscosity class SAE 30 if you own a lawnmower with a 4-stroke engine.

  • Lawn mower oil SAE 30 can be found in any well-stocked online shop.
  • With an SAE 30 motor oil one speaks of a monograde oil, which is usually only suitable for operation in the warm months.
  • Accordingly, a lawnmower oil SAE 30 is suitable from spring to autumn.
  • Alternatively, you can also use a multigrade oil (e.g. 10W-30. designed for summer and winter use).

However, this is only recommended if it is recommended in the user manual.

How do I know if my lawn mower is 2 or 4 stroke?

– Look for labels on the devices (e.g. ‘four-stroke’ or ‘do not use mixed fuel’).

Which is better gasoline 95 or 98?

What are the differences between unleaded 95 and 98? – The main difference between 95 unleaded and 98 unleaded gasoline is octane rating, a measurement that indicates the fuel’s resistance to combustion when compressed in an engine’s cylinder. Unleaded 95 has an octane rating of 95, unleaded 98 has an octane rating of 98! The remaining portion (5% or 2%) corresponds to heptane.

Unleaded 98 has a higher flammability than unleaded 95. This is due to the behavior of the hydrocarbons that make it up: octane is more resistant to combustion. So the higher the octane number, the more controlled the combustion of the gasoline and the more efficient the engine. So, in order to ensure a longer service life for our vehicle, we should theoretically fill up with petrol with the higher octane number, i.e. petrol with 98 octane.

However, 95 unleaded petrol is cheaper at the pump and the fuel premium over 98 unleaded petrol is estimated to be less than 2%, making it a popular cheaper option for motorists. If your car is a classic, 95 unleaded petrol is the most recommended.

What happens if you fill up with Super E95 instead of Super 10?

What happens if the vehicle does not tolerate E10? – However, if a car does not tolerate the Super E10, the fuel can attack aluminum components as well as seals and lines in the fuel system after refueling – and thus become a safety risk.

In the event of incorrect refueling of a non-approved car with E10, the vehicle manufacturer’s instructions should be observed. According to ADAC, however, it may be sufficient to immediately fill up the tank with a low-ethanol type of fuel. preferably Super Plus. in order to achieve an ethanol mixture ratio that is as uncritical as possible.

If, on the other hand, the tank was filled to the brim with E10, it might be necessary to pump out the fuel. In this case you should contact the manufacturer. : What you need to consider: Is it safe to fill up with cheaper E10?

What happens if you fill up with E95 instead of Super 10?

Filled up with Super E10 instead of Super E5? This is harmless if your vehicle is generally approved for. Otherwise, even a single erroneous tank filling with E10 can lead to serious damage. In the event of incorrect refueling with E10, you should observe the vehicle manufacturer’s instructions.

Is it bad if you mix E5 and E10?

The E10 marking at the gas station. To avoid misfuelling of E10-incompatible vehicles, a clear and conspicuous marking of E10 is necessary both directly at the pump and on the signage of the prices: Pumps for Super E10 must be marked Super E10 and the circle symbol with E10 in the center.

  • In addition, the fuel standard (DIN EN 228) and the octane number (ROZ95) must be specified, as well as the two notes: Contains up to 10% bioethanol and Can your vehicle tolerate E10? Obtain manufacturer information! If in doubt, fill up with Super or Super Plus!”.
  • Vehicles that are E10-compatible can be refueled alternately or as a mixture of E10 and E5 fuel.

This is without risk, no vehicle damage is to be expected here.

Can you also use car oil for lawn mowers?

Car oil. If there are still engine oil residues from the last refill of the car or if a car oil is currently being offered cheaply, you should not be tempted and ultimately never use it for a lawnmower. A motor vehicle oil is usually a so-called multigrade oil.

  • This means that the temperature fluctuations of the different seasons and trips to other climate zones can be compensated.
  • The multigrade oil is therefore so important for cars so that the lubricating film does not tear through.
  • If the motor vehicle oil were to be used in a lawn mower, which is normally only put into operation in warmer temperatures between spring and late summer, this can significantly accelerate the wear of the lawn mower engine.

An exception is the use of car oil in lawn tractors, which are also used in winter. In this case, for example, an SAE 5W-40 fully synthetic oil is recommended.

How often do you have to add oil to a lawnmower?

When and how often should a lawnmower oil be changed? – Basically, the manufacturer specifies how often the oil in your lawnmower should be changed. In general, however, an oil change is recommended once a year, or at the latest after 25 working hours.

  • It is best to carry this out when you are grooming it when you are preparing it for the winter break! The oil change can be done in two ways: On the one hand, you can tilt the lawnmower and let the oil drain out through the open drain plug.
  • Since this variant is usually an oily and dirty affair, you can also carry it out with the help of an oil change set.

It is advisable to change the oil when it is warm. On the one hand, it flows better and dirt and wear elements are flushed out better. So start it up and let it run for a few minutes. Then switch off the engine and pull the spark plug connector.

What happens if petrol sits too long?

Can be kept for several months – Basically, fuel is a product with a limited shelf life, and not just because it is eventually ignited in the combustion chamber. Gasoline stored for too long will spoil sooner or later and start aging as soon as it leaves the refinery.

  • Experts from the industry are certain that petrol can be kept for between two to three months or up to a year without any measurable loss of quality.
  • The main factors in aging are: How much light and ambient air gets to the petrol and whether high temperature fluctuations affect the fuel.

The petrol will age faster in an open canister than in a filled and closed canister. The fuel tank on the motorcycle is somewhere between these two storage methods, and what is particularly important is how much air, i.e. how little petrol, is in the tank.

What happens when gasoline is too old?

Gasoline Shelf Life. Gasoline shelf life is dependent on many factors and cannot be accurately predicted. When stored airtight in metal canisters, petrol can theoretically last for many years, or even several decades depending on the composition.

Order fuel canisters on Amazon (ADVERTIES) The most important requirement for this, however, is that the gasoline is stored airtight. However, this is not the case in the tank of a car, motorcycle or truck. Depending on the composition of the petrol and the nature of the tank, flammable substances and octane ratings can escape.

The general quality of the fuel also decreases. If the petrol in the tank is very old, it can even happen that the vehicle does not start at all. As a rule, however, petrol can be kept in the tank for 1 to 2 months before the quality of the fuel begins to deteriorate.

On which side can you tip the lawnmower?

Gasoline powered lawnmowers are designed to be tilted so that the spark plug is pointing ‘up’. This prevents the oil from overflowing from the engine sump and flooding the air filter, carburettor, cylinder head. If possible, the fuel tank should be completely empty.

Which is better 2 or 4 stroke?

Structure and function of a 4-stroke engine. In comparison, the function of a 4-stroke engine consists of four work steps: intake, compression, work and exhaust.

Electric VS Petrol Lawnmowers | The Gadget Show

A petrol-air mixture is generated in the carburetor and sucked in by the downward movement of the piston. The fuel-air mixture enters the cylinder through the open intake valve. In newer engines, the fuel-air mixture is injected into the cylinder at high pressure. This is then referred to as direct injection.

lawn, mower, fuel, consumption

The fuel-air mixture is compressed by the piston moving upwards when the valves are closed. Pressure and temperature increase. Shortly before top dead center, the fuel-air mixture is ignited by an electric spark at the spark plug.

The fuel-air mixture burns explosively. The pressure and temperature in the cylinder increase dramatically. The piston is moved downwards as a result of the high pressure and performs mechanical work. The reciprocating movement of the piston is converted into a rotary movement via the connecting rod and crankshaft.

The piston moves up again and pushes the combustion gases out of the cylinder through the open exhaust valve. The process then begins again with cycle 1. A 4-stroke engine consumes less petrol and oil than a 2-stroke engine.

Which petrol for two-stroke engines?

What is alkylate petrol? – Alkylate petrol is a type of petrol specially made for small appliances with two-stroke engines and is also known as equipment petrol. It is particularly low in harmful substances and can therefore also be used where the operator is directly exposed to exhaust fumes, such as with chainsaws.

What is the difference between 2 and 4 stroke?

How does a 2-stroke motorcycle engine work? – A two-stroke engine works differently than a four-stroke engine. A power cycle takes place with each piston revolution. The steps of suction, compression, combustion and expulsion take place simultaneously. During the upward movement of the piston, fresh air is drawn into the cylinder through the intake manifold and at the same time fuel is injected into the cylinder and ignited.

  • As the piston moves down, the used air-fuel mixture is expelled through the outlet.
  • Since intake and exhaust take place in one stroke, it is called a two-stroke engine.
  • A two-stroke engine is typically smaller, lighter and more powerful than a four-stroke engine, but also more sensitive and inefficient when it comes to fuel consumption and emissions.

These differences lead to a number of advantages and disadvantages compared to 4-stroke engines.

Is E10 better than Super 95?

If you fill up with E10 instead of Super 95, your car will use around 1% more petrol. That’s why E10 is a few cents cheaper at the gas station. Rule of thumb: From 3 cents less per liter, the additional consumption is compensated and E10 is worth it compared to Super 95. And which cars can tolerate E10? Practically all petrol cars built after 2011, some even older ones. Author Status: August 5, 2022 The Finanztip editorial team consists of a team of experts who will research for you so that you can make the best decisions. You can read more about how we work here,

Can every petrol engine fill up with Super 95?

Super and Super Plus: which cars can fill up the fuel? – Unlike the E 10, there are no restrictions on which petrol cars can be refueled with Super and Super Plus or not. All gasoline tolerate Super as well as Super Plus.

Which petrol is better E10 or Super 95?

Which is better: E10 or Super 95? – Since E10 contains more ethanol than Super 95, the cost is lower, but the fuel consumption is higher because the energy content in E10 fuel is lower. Many consider E10 to be a greener alternative.

What kind of oil goes in a lawn mower?

Recommended oils for small engines: –

Use SAE 30 in warmer temperatures of 5°C and above Use SAE 10W-30 in temperature ranges varying from.18°C to 38°C; this oil grade improves starting in cold weather but can increase oil consumption at 27°C and above. A synthetic oil, SAE 5W-30, is best in cold temperatures from.30°C to 40°C and provides the best protection at all temperatures and improved starting with less oil consumption Use SAE 5W-30 in very cold temperatures of 5°C and below For continuous use such as landscape maintenance or pressure washing companies use Vanguard 15W-50 oil (temperatures of 20 °F to 130 °F)

What to consider when choosing lawnmower oil:

Only use quality oils with the classification “SF, SG, SH, SJ” or higher. Do not use special additives. Synthetic oils are acceptable at all temperatures. When using synthetic oil, the required oil change intervals do not change.

Can you use synthetic lawn mower oil? Yes! We have recently modified our motor oil recommendations so that you can now use a synthetic 5W30 or 10W30 oil in all temperature ranges. We recommend that you use Briggs Stratton synthetic oil. The use of the high-quality, detergent oil ensures compliance with the Briggs Stratton warranty requirements regarding the use of suitable oil.

  • Engine break-in procedures with synthetic oil remain unchanged.
  • Please note that the use of synthetic oil does not obviate regularly scheduled lawnmower maintenance (ie
  • Oil check, change, etc.) Engine Oil Capacity Engine oil capacity, like oil type, is dependent on your specific engine model.

To learn how to check the lawnmower oil, see our “Engine Oil Check. Lawnmower Engine”.

What is 4 stroke petrol?

Which engine oils are suitable for 2-stroke or 4-stroke engines? Since 2-stroke and 4-stroke engines differ in their structure and do not have the same function, different requirements are placed on the engine oils.

Because the 2-stroke engine oil is supposed to function in the fuel – as a mixture – it must also have properties for the cleanest possible combustion in addition to its lubricating tasks. That is why 2-stroke engine oils were developed, which burn with low emissions and only have a low ash content.

They must mix well with the fuel and also have a low viscosity. 4-stroke engine oils are not designed for combustion, but for a long service life. They have a higher sulphate ash content, high pressure resistance and have appropriate additives to protect the engine from corrosion and wear.

How much fuel does a lawn mower need?

Gasoline mowers in the cost check. for a gasoline mower from a brand manufacturer with a cutting width of 40 centimeters, the acquisition costs are around 300 euros, a petrol canister costs another around 20 euros. The cutting width can be a little smaller than with an electric mower. since you don’t have to calculate time for cable handling, you can also finish a 500 square meter lawn after one hour.

As far as operating costs are concerned, petrol lawn mowers are the most expensive: modern lawn mower engines consume 0,6 to 1 liter of unleaded petrol per operating hour, depending on performance. If you take a price of 1,50 euros as a basis, the fuel costs for 34 hours of operation per season are at least 30 euros.

In addition, there is a relatively high maintenance effort, because petrol mowers need a service including an oil change once a year. Cost: around 50 euros, depending on the workshop. As with the electric mower, you also have to calculate 60 euros for lawn fertilization with the petrol mower and the working time is also comparable at around 48 hours.
