Understanding the Fuel Requirements for Push Lawn Mowers

When it comes to maintaining your push lawn mower, one of the critical aspects is fueling it with the correct type of gasoline. This article will delve into the common types of gasoline used by push lawn mowers and offer essential tips to ensure optimal performance.

What Type of Gasoline Should I Use?

The most commonly recommended type of gasoline for push lawn mowers is regular unleaded gasoline with an octane rating of 87. This is readily available at most gas stations and is suitable for the majority of small engines, including those found in push mowers.

Importance of Gasoline with 10% or Less Ethanol

To protect your lawn mower's engine, it is crucial to avoid using gasoline with more than 10% ethanol, often referred to as E10. Higher ethanol content, such as E15 or E85, can be detrimental to small engines due to their corrosive properties and the resultant damage to carburetors and other components.

Precautions for Fuel Storage and Dehydration

It is essential to use fresh gasoline and to avoid storing fuel in the mower for an extended period. Stale gasoline can degrade, leading to a buildup of gum and varnish, which can clog fuel lines and engines. This not only affects performance but can also result in costly repairs.

Manufacturer Recommendations

Always consult your lawn mower's owner's manual for specific fuel recommendations. Manufacturers often tailor their recommendations based on the mower's specifications and intended use. A lawnmower shop can provide additional insights and ensure you are using the best fuel for your specific model. For convenience, many users prefer to fill their mower gas can with the same gasoline they use for their vehicles, typically regular unleaded gasoline.

Conclusion

Maintaining your lawn mower with the correct type of gasoline is key to ensuring its longevity and performance. Regular unleaded gasoline with an octane rating of 87, with a maximum of 10% ethanol, is generally recommended. Storing fresh, high-quality fuel is crucial for optimal performance and to prevent engine damage. Always refer to your owner's manual for specific recommendations, and if you are unsure, seek advice from a local lawnmower shop.
