Always check the ethanol content before filling up your mower. Ethanol can cause corrosion and other issues. Using gas with less than 10% ethanol is best.
Understanding Octane Ratings
Understanding octane ratings is crucial for maintaining your lawn mower. Different octane levels can impact your mower’s performance. Knowing the right octane rating can make your mower run smoothly. This section will help you understand octane ratings better.
Low Vs High Octane
Octane ratings measure a fuel’s ability to resist knocking. Regular gasoline usually has an octane rating of 87. Premium gasoline often has a rating of 91 or higher. The higher the octane rating, the more resistant the fuel is to knocking. Knocking can damage your mower’s engine over time.
Most lawn mowers run well on regular gasoline. High-octane fuel is usually not needed for small engines. Check your mower’s manual for the recommended octane rating. Using the wrong octane can affect performance and efficiency.
Impact On Performance
Using the correct octane rating ensures your mower operates efficiently. Low-octane fuel can cause knocking and reduce engine life. High-octane fuel can help in high-performance engines. But, for most lawn mowers, high-octane fuel does not improve performance.
Regular gasoline is often sufficient for lawn mowers. Over time, using the recommended octane helps maintain engine health. Always refer to your mower’s manual for the best fuel type. Proper fuel use keeps your mower running smoothly and efficiently.
