What gasoline is best for small engines?
What is the best small engine or lawn mower gas?

- Gasoline with up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl ether), is acceptable.
Do small engines use high or low octane fuel?
Small engines have low compression ratios, meaning they won’t likely benefit from anything special in the gas like a higher octane rating. Some premium fuels may actually make your equipment harder to start. So save your money and use regular gas.
Is non ethanol gas better for small engines?
Benefits. Premium Non-Ethanol Gasoline can improve mileage, provide better performance and safer operations for your summer engines. Its also more stable for long term storage, and less destructive to engines and fuel systems.
What is the most common fuel source used in small engines?
Gasoline is the most commonly used U.S. transportation fuel
Gasoline includes aviation gasoline and motor gasoline. Finished motor gasoline includes petroleum gasoline and fuel ethanol. Fuel ethanol includes ethanol (a biofuel) and petroleum denaturants.
You should use regular gas in your lawn mower. Running a smaller engine on premium gas isn’t necessary. Premium gas is designed for engines with a higher compression ratio which are generally found in high powered cars. While premium gas may not hurt your mower’s engine, it will hurt your wallet.
What gas is best for lawn mower?
Use 87-octane, 10% ethanol gas
As a rule of thumb, a minimum of 87-octane containing up to 10% ethanol is the recommended gas for lawn mowers. Ensure that the gas is fresh and clean as these fuels degrade rather quickly. It might not be a good idea to use leftover fuel from last season before winter.
Is it OK to put 93 octane in a lawn mower?
Premium gas, such as 93 octane, helps high-powered cars run smoothly and efficiently. … There’s no need to run a small lawnmower engine on high-octane gas, but it won’t hurt your lawnmower, either. The only harm might be the dent left in your wallet from using the more expensive fuel.
What fuel does my Briggs and Stratton use?
A minimum 87 octane containing up to 10% ethanol is recommended. Do not use fuels with 15 to 85% ethanol, these fuels are not approved for use in small engines. Mixing oil with gasoline or modifying your 4-Cycle small engine to run on alternative fuels will damage the engine and will not be covered under warranty.
Should I run ethanol free gas in my lawn mower?
However, when you’re using gas with ethanol mixture in your outdoor power equipment, like lawn mowers, chainsaws, trimmers and leaf blowers, you run the risk of engine damage and incurring costly repairs. You should be using ethanol free gas in your small engine outdoor power equipment.
What kind of gas does a Honda lawn mower use?
Honda engines are designed and certified to run on regular unleaded gasoline. Gasoline is allowed, by regulation, to contain a variety of additives. The same regulation limits how much of some additives, such as alcohol, can be included in the fuel and still allow it to be sold as gasoline.
Does 93 octane have ethanol?
All gasoline brands have both pure and ethanol-containing gasoline under the same brand names. For example, Shell V-Power ranges from 91 to 93 octane both with and without added ethanol. It just varies from station to station, and it’s up to the station owner whether or not to sell pure gas.
Why is ethanol gas bad for small engines?
“Ethanol has inherent properties that can cause corrosion of metal parts, including carburetors, degradation of plastic and rubber components, harder starting, and reduced engine life,” says Marv Klowak, global vice president of research and development for Briggs & Stratton, the largest manufacturer of small engines.
What is the cleanest burning fuel?
Compared with some other fossil fuels, natural gas emits the least amount of carbon dioxide into the air when combusted — making natural gas the cleanest burning fossil fuel of all.
Why is propane bad?
Propane is not safe for the environment. Propane is a liquid when stored, and when released into the air, it vaporizes and dissipates with no ozone-harming effects. This means it cannot contaminate groundwater, drinking water, marine ecosystems or sensitive habitat if released. Electricity is better than fossil fuels.
Why is propane a good fuel?
Propane has a high octane rating, making it an excellent choice for spark-ignited internal combustion engines. If spilled or released from a vehicle, it presents no threat to soil, surface water, or groundwater. Propane is produced as a by-product of natural gas processing and crude oil refining.
