The way rotary lawn mower blades work is very similar to a blender or a food processor.

Let’s Learn About Lawn Mowers

Before we talk about fuel; we need to talk a little more about lawnmowers.

There are a huge variety of different lawnmowers from ride-on mowers, manual push mowers, motorized push mowers, and hand-held lawn trimmers.

Today, we are focusing on rotary mowers, as they are the most common and use gas to power them.

Rotary mowers are what probably first comes to mind when you think of lawn mowers. They consist of a body that houses the engine, which sits on four wheels. This is pushed along by a sturdy metal handle.

They are great for small lawns, making them popular for domestic uses. They cut the lawn using one sharp blade that rotates at high speed.

Rotary mowers have a two or four-stroke combustion engine that runs on regular gas. We will go into this in a little more detail later.

The benefit of having a gas engine in your lawn mower is that there is no cable to plug in that you could run over by accident.

It is essential to use fresh, clean gas, so we recommend only buying enough to use within a 30-day period and storing it in a metal gas canister that is sealed tight.

Do Lawn Mowers Take Regular Gas?

If you are using regular unleaded gas, then you can use it in your lawn mower.

This is not the case for all forms of gasoline, however.

Here is a quick guide on what fuel will or won’t work for your lawn mower.

Fuel Suitable for a lawn mower
Unleaded (all variants) Yes
Non-oxygenated Yes
Diesel No
E15- E85 No

Due to the engine that lawn mowers have, it is very important to choose the right fuel for your machine to work. If you use diesel by accident, for example, it could damage your lawn mower engine irreparably.

The ideal gas to use for lawn mowers is E10, 87 octane fuel. This means the gas is 10% ethanol and can handle an appropriate amount of compression. Most regular unleaded gas will fit these criteria.

As we mentioned earlier, your mower will have a two or four-stroke engine, and while they both use regular gas, there is one key difference between them.

In a four-stroke engine, the oil is kept in a separate part of the engine. In a two-stroke, however, the oil must be mixed with the gas in a specific ratio. We suggest referring to your lawn mower manual to learn the proportions you need to mix.

As a guideline, we don’t recommend using petrol over E10, because that level of ethanol is not suited to lawn mower engines.

Grow Your Yard Fact
Transporting and storing gas can be risky. To be safe, we recommend buying a sturdy, metal gas canister reserved for safely transporting your lawn mower fuel. The fuel should be stored away from children and animals and open flames.

What is the Best Fuel to Use in My Lawn Mower?

Our recommendation is to use any form of unleaded gas.

This is for several reasons. Firstly, it’s easy to get hold of. Simply pop down to your local gas station and fill up a can. You can even pick it up at the same time as you fill up to save time.

 Secondly, although gas is very expensive, regular unleaded is just that little bit more affordable than other premium fuels.

Unleaded fuel ticks all the boxes for great fuel and will keep your mower running with ease.

Frequently Asked Questions:

What is the cheapest kind of lawn mower to run?

At the end of the day, lawn mowers can be expensive to run because of the price of gas.

If you are on more of a budget, you might consider a manual lawnmower like a cylinder push mower. These will only cost you the initial investment to buy the mower as it doesn’t use petrol or electricity to run.

Do lawn mowers need premium gas?

While premium gas will work perfectly well in your lawn mower, is it unnecessary.

As you can see from this article, regular unleaded gas works perfectly fine, so using premium gas would just be a waste of money. Save the good stuff for your car and stick with regular unleaded gas for your lawn mower.

Conclusion

So, at the end of the day, the general answer is yes, you can use regular gas in your lawn mower.

As long as you avoid certain fuel types and stick to unleaded, your mower will run along happily. Our recommendation is to buy regular unleaded gas in small amounts. This will save you money and ensure your mower runs on clean, fresh gas.

Now, off you go and mow that lawn!
