What Gas To Use In Lawn Mower?

When it comes to fueling your lawn mower or outdoor power equipment, using the right type of gasoline is paramount to ensure optimal performance and longevity of your machinery. An important aspect to consider when selecting the appropriate fuel is the octane rating, as it plays a crucial role in the combustion process within the engine.

Understanding the Octane Requirement

For most lawn mowers and small engines, a minimum of 87 octane or 87 AKI (91 RON) gasoline is recommended to maintain smooth operation. Lower octane fuels may lead to knocking or pinging noises during operation, which could potentially cause damage to the engine over time.

Quality and Ethanol Content

It is essential to use clean, fresh, and unleaded gasoline in your lawn mower. Gasoline containing up to 10% ethanol (gasohol) or up to 15% MTBE (methyl tertiary butyl ether) is generally considered acceptable for use in small engines. However, it is important to avoid using fuels with higher ethanol content, as they can lead to performance issues and damage to the fuel system.

Why Choose Briggs & Stratton

Briggs & Stratton, a renowned manufacturer of small engines and lawn mower equipment, recommends using high-quality gasoline with the appropriate octane rating for their products. By following their guidelines, you can ensure that your lawn mower operates efficiently and maintains optimal performance throughout its lifespan.

Benefits of Using the Correct Gas

Using the right type of gasoline in your lawn mower offers a range of benefits, including improved fuel efficiency, smoother engine operation, and reduced emissions. By adhering to the manufacturer’s recommendations, you can prolong the life of your equipment and avoid costly repairs down the line.

Considerations for High Altitude Operation

If you live in a high-altitude area, it is important to adjust your fuel selection accordingly. At higher elevations, the air is less dense, which can affect engine performance. In such cases, using a higher octane fuel or a fuel specifically designed for altitude operation may be necessary to maintain optimal power output.

Fueling Best Practices

When refueling your lawn mower, always use a clean container and pour the gasoline carefully to avoid spillage. It is recommended to refuel your equipment outdoors in a well-ventilated area to prevent exposure to harmful fumes. Additionally, make sure to cap the fuel tank securely after refueling to prevent contaminants from entering the system.

Storage and Maintenance

Proper storage of gasoline is essential to maintain its quality and prevent engine issues. Store fuel in a cool, dry place away from direct sunlight and sources of heat. It is also important to use fuel stabilizers to prolong the shelf life of gasoline and prevent it from going stale over time.

Consulting the Owner’s Manual

For specific guidance on fuel selection and usage, always refer to the owner’s manual provided by the manufacturer of your lawn mower. The manual contains valuable information on fuel requirements, maintenance procedures, and troubleshooting tips to keep your equipment running smoothly.
