Regular or Premium Gas for Lawn Mower: What to Use?

Have you recently purchased a lawn mower but are confused about whether you should choose regular or premium gas for lawn mower? 

Indeed, regular and premium gasses function almost similarly. However, some latest mowers have an engine that can be run on premium gasses only. But in most cases, regular gasses are quite friendly with the majority of mowers’ engines with their 87 octane rating and moderate ethanol.  

By knowing the differences, you can decide which gas fits your mower most among the premium and regular gas. So, go on!

Does Lawn Mower Take Regular Gas?

Indeed, most lawn mowers take regular gas to run for being incorporated with 4-stroke engines. The gas they often use needs an 87 octane rating or more, including 10% ethanol. 

However, some owners prefer gas that is totally ethanol-free so that it will not bring any unnecessary pressure on the lawnmowers’ interior parts. 

Regular or Premium Gas for Lawn Mower: What Should You Use? 

Before you know which type of gas you should use for your lawn mower, it is necessary to get familiar with their characteristics and differences. 

Depending on the engine type, the requirement of a particular gas will be varied. So let us share a detailed overview by disclosing their differences –

Octane Level 

Octane Level 

In terms of measuring the fuel’s knock resistance, the number of octane plays a key role. As a basic rule of thumb, high octane level confirms high compression. 

For optimum mowing performance, some mowers need extended octane levels, although it is not common in every lawnmower. 

In fact, most mowers are able to continue their task with regular gas that contains 87 octane fuel. 

This is cost-efficient, and at the same time, can perform pretty much better going through regular mowing tasks. 

On the other hand, the majority of premium gasses consist of 93 or more octane levels, which will charge extra bucks compared to regular gasses!


Only a certain lawn mower engine will hardly need premium gasses to survive efficiently. In fact, some manufacturers have made their mowers’ engines in such a way that they will not run on regular gasses. 

Apart from this matter, we believe that you will not notice any significant difference by incorporating premium gasses on your mower that can run over regular gasses. 

And it is a clear myth that premium gasses are more fuel efficient than regular ones. Rather, the level of efficiency highly depends on your mower’s engine condition and overall usage. 


Can you guess the key reason behind purchasing premium gasses by spending a fortune? This is because the premium fuel prevents unexpected knocking on the high-performing engines for being added with higher octane. 

And this is what makes the premium fuel slightly more expensive than the regular gas.

What Fuel Does My Briggs and Stratton Use?

What Fuel Does My Briggs and Stratton Use

Your Briggs and Stratton engine will use either gasoline or ethanol-blended fuel. If your engine is designed for unleaded gasoline, it will run on up to 10% ethanol-blended fuel. If you’re unsure which fuel to use, check your owner’s manual or contact a Briggs & Stratton dealer.

You can also find this information on the label of your engine, located above the oil fill cap. The U.S. Environmental Protection Agency (EPA) has approved using E10 in all engines since 1979. Ethanol-blended fuels are called gasohol; most contain 10% ethanol and 90% gasoline.

Ethanol is an oxygenate that helps reduce emissions of carbon monoxide and hydrocarbons. It is produced from renewable resources such as corn, sugar cane or wood. Briggs & Stratton does not recommend using fuel containing more than 10% ethanol in its engines.

Higher ethanol concentrations can cause starting and performance problems and damage your engine.

What type of petrol does an e10 lawn mower take?

Consider choosing moderate ethanol gasses for your e10-friendly mower. It is not recommended to use petrol that contains a higher ethanol rating than the e10. Because this can bring complexity to the small engines of your mower. 

How long does the non-ethanol gas last?

If you seal or store the non-ethanol gas correctly, it may last a minimum of six months. With proper storage, it is possible to reduce the chance of degradation caused by exposure to atmosphere situations.


You’re not alone if you’re unsure what type of gas to put in your lawn mower. Consider a few things before filling up your tank. The most important thing is to make sure you use fresh gas.

Gasoline can go bad after just a few months, so buying it fresh and using it within a month or two is important.

It would help to use the right octane rating for your lawn mower. Most lawnmowers will run fine on 87-octane gasoline, but if yours is designed for higher-octane fuel, be sure to use that instead.
