All homeowners need to mow their lawn regularly to keep it good looking. Most of them do the mowing themselves; in fact, many enjoy mowing the lawn themselves. To keep your mower rolling, you need to fill the gas tank. The type and amount of gas to use can vary depending on the type of mower. How much gas will my mower need per acre, what kind of gas to use, and how to save gas when mowing is among the basic questions that new and inexperienced mower owners usually have. We’ll provide you all the relative information in this regard.
How Much Gas Does a Lawnmower Use?
Walk-behind or push mowers usually have a tank from 1 to 3 qts. Generally, a push mower does about half an acre per tank. Riding mowers have a bigger engine and are often used for bigger lawns or rough terrains involving more acceleration. For this reason, the fuel consumption needs of a riding mower are usually higher as compared to push mowers. A medium-sized riding mower generally has a gas capacity of around two gallons at most. For larger riding mowers and tractors, a capacity of three to four gallons is not uncommon.
What type of gas does my Lawn Mower use?
The type of gas not only depends on the kind of mower but also on the working environment. There are some general guidelines, though. For example, according to experts, any gas with more than 10% ethanol should not be used, or else your engine might end up damaged after only two fill-ups.
For the most specific and accurate answer on the amount of gas and the gas type you should consult the owner’s manual that came with the mower.
Having made the basics clear, let’s get into the details of gas capacities of some common mower types, how to fill gas in a lawnmower, and other essential things to keep in mind regarding gas lawnmowers.

How Much Gas to Put in a Gas Lawnmower?
As said earlier, the most specific and accurate answer to this question depends on the type, make, and model of your mower, and you can consult your owner’s manual for this answer. However, there are a few basic types of lawnmowers based on the intensity of duty and weight of the machine, etc. These types include walk-behind lawnmowers called push mowers, riding mowers of which there are a couple of types, and larger tractors. These mowers’ gas capacity is general information for lawnmower owners and having a basic knowledge of these things is good if you are planning on being one.
Usually, “per acre” is used as a unit to measure the quantity of gas used in mowers. And similarly, the cost of fuel is also calculated per acre, generally.
● Push Mowers:
Push mowers are mostly intended for smaller, level areas and lighter duties. There aren’t many bumps involved, so the fuel consumption is lower. The fuel capacity of household push mowers is generally half a liter at most, and you can mow half an acre in one tank. Therefore, two tanks or one liter is sufficient enough for an acre. Some push mower models may have a little higher gas capacity, which can be found in the manual.
● Riding Mowers:
When it comes to heavier duty, uneven ground with bumps, and higher acceleration, a push mower can no longer adequately serve the purpose. So, riding mowers are used for mowing rough terrains. Riding mowers further have types based on size. For smaller riding mowers, the fuel consumption per acre is 20% to 40% more than push mowers. Medium-sized riding mowers typically have a capacity of around 2 gallons of gas.
● Tractor Styled and Commercial Mowers:
Larger riding mowers and tractor styled mowers can go up to two to three gallons. Commercial type mowers consume more gas per acre compared to homeowner mowers. The largest commercial type mowers can hold five to six gallons, which enable operators to mow for extended periods of time.
How to Save Gas?
Who doesn’t want to save gas when saving gas translates directly to saving money?
There are some methods and techniques that, when followed, can help you save gas and, ultimately, money. So, these considerations should always be kept in mind.
● Use Fresh Unleaded Fuel:
The most important thing to remember is always to use fresh unleaded fuel. If you let the gas stay in the engine for too long without using or use old fuel, it will start breaking down in the engine, reducing your mower’s performance. With decreased performance, you will be forced to use more fuel for the same output, increasing the total price per acre. Mixing fresh gas with old gas is not a great idea, either. The old gas will contaminate the fresh gas, and you will end up dumping both the old and new.
● Use Fuel Stabilizer:
If you have a full tank of gas in your lawnmower, but you want to store your mower for later use, you should use a fuel stabilizer to keep the fuel intact. A fuel stabilizer will prevent the gas from evaporating and help preserve the fuel quality.
● Altitude Adjustments:
Without proper adjustments at higher altitudes, the performance of a lawnmower decreases, leading to more fuel usage. Above 5,000 ft. altitude adjustments are a must. In addition to altitude, bumps, accelerations, roughness, etc., should also be considered. Maneuvering the mower at a steady pace in these conditions will lower gas consumption and save money.
What Type of Gas to Use?
All lawnmowers don’t use the same type of gas, and to be completely sure about the type of gas you should be using, refer to the owner’s manual. However, some general guidelines must be followed for the gas type.
Lawnmower engines generally use high-grade unleaded fuels and fuel-oil mixtures. For a home owned lawnmower, the fuel should have a minimum octane rating of 87.
Gasoline with greater than 10% ethanol must never be used in lawnmowers. On the other hand, gas with above 15% MTEB is a good choice.
Gas choice also depends on altitude. For altitudes above 5,000ft., the minimum octane rating of the fuel should be 85.
Mixing parts of gasoline and oil depending on the specific needs of an engine is also not uncommon. Mixing 50 parts gas to 1 part of the oil is a common practice for many mower owners.
● Gas Types for Four-Stroke and Two-Stroke Engines:
For a four-stroke engine, go with gasoline with an octane rating of 87 or more. The fuel should be fresh and unleaded.
You can use the same gas in a two-stroke engine, but it’s recommended to add two-cycle engine oil.
How to Fill Gas?
Filling gas in your lawnmower follows the following four steps that are easy enough:
● Locate the Tank:
The gas tank in most mowers is usually located on a side on or at the back. The gas tank is covered and hidden in some mowers and has to be found under a cover or from a symbol.
● Remove the Cap:
Mostly, the cap is removed by rotating it counter-clockwise. In some cases, the cap is locked in place, or a key is needed to open it.
● Fill Up:
Use a nozzle or funnel to avoid spilling or splashes. Pay attention to the fill line of your gas tank.
● Put the Cap Back On:
The final step is to put the cap back on and tighten it, and then you are good to go.
Can you use Car Gas in your Lawnmowers?
In many cases, the answer is yes if the car fuel is unleaded and does not have more than 10% ethanol, it’s safe to be used in the mower.
To confirm that your car fuel is safe for the mower, you can consult the manual or get info from the internet.
● How can I remove fuel from my lawnmower?
You can use a liquid hand pump with one side in the mower’s fuel tank and the other in the gas can. Make sure the fuel line is disconnected before you do so.
● Can car fuel be used in lawnmowers?
Refer to the owner’s manual for the most specific and correct answer. But generally, yes. Just make sure that the octane rating of the fuel you are using is in the right range, and the fuel has less than 10% ethanol.
Lawnmowers are expensive machines, and all owners desire for their mowers to have a longer life span. Choosing the correct type of fuel for your mower based on the make and model and intended use and operation environment and keeping the gas in the fuel tank at the right level sure helps in a good performance and increased life of the mower. You can get all info about the type and amount of gas for your mower from the owner’s manual, but some general guidelines should be followed. For example, ethanol in the gas should be less than 10%, etc.
