Can You Safely Use Non-Ethanol Gas in Your Lawn Mower?

Using the right fuel for your lawn mower is crucial for its performance and longevity. One common question that arises is whether it is safe to use non-ethanol gas in a lawn mower. In this article, we will explore this topic and provide you with the necessary information to make an informed decision.

The Pros and Cons of Non-Ethanol Gas

Non-ethanol gas, also known as pure gasoline, is fuel that does not contain any ethanol additives. Here are some pros and cons to consider when using non-ethanol gas in your lawn mower:

1. Better fuel efficiency: Non-ethanol gas tends to provide better fuel efficiency compared to ethanol-blended gasoline. This means you can mow your lawn for a longer time without having to refuel.
2. Reduced engine deposits: Ethanol can leave behind residue and deposits in the engine, potentially causing issues with performance. Non-ethanol gas reduces the likelihood of these deposits, leading to a cleaner and more reliable engine.
3. Longer shelf life: Non-ethanol gas has a longer shelf life compared to ethanol-blended gasoline. This is particularly beneficial if you store your lawn mower during the winter months or for an extended period.

1. Higher cost: Non-ethanol gas is generally more expensive than ethanol-blended gasoline. This can add up over time, especially if you have a large lawn or frequently use your lawn mower.
2. Limited availability: Non-ethanol gas may not be readily available at all gas stations. You might need to search for specific stations that offer this type of fuel, which can be inconvenient.

Considerations for Using Non-Ethanol Gas in Your Lawn Mower

Before deciding to use non-ethanol gas in your lawn mower, there are a few important considerations to keep in mind:

1. Manufacturer’s recommendations: Check the owner’s manual or contact the manufacturer to see if they recommend using non-ethanol gas in your specific lawn mower model. Following their guidelines will ensure optimal performance and prevent any potential warranty issues.
2. Ethanol-blended gas alternatives: If non-ethanol gas is not readily available or too expensive, consider using ethanol-blended gas with a lower ethanol content. Some gas stations offer options with lower ethanol percentages, such as E10 (10% ethanol) or E15 (15% ethanol). These blends can provide a balance between cost and performance.
3. Fuel stabilizer: If you choose to use ethanol-blended gas, consider adding a fuel stabilizer to prevent ethanol-related issues such as phase separation and fuel degradation. This will help maintain the quality of the fuel and protect your lawn mower’s engine.


In summary, using non-ethanol gas in your lawn mower can have its benefits, such as improved fuel efficiency and reduced engine deposits. However, it is essential to consider the higher cost and limited availability of this fuel type. Always consult the manufacturer’s recommendations and explore alternative ethanol-blended gas options if necessary. Remember to use a fuel stabilizer if you opt for ethanol-blended gas to protect your lawn mower’s engine. By making an informed decision, you can ensure the optimal performance and longevity of your lawn mower.
