Service Miscellaneous

Using Proper Fuel

Use regular grade unleaded fuel with an octane rating of 87 octane or

higher. Fuel blends containing up to 10% ethanol or up to 15% MTBE

reformulated fuel are acceptable. Do not use fuel or additives containing

methanol as engine damage can occur.

Always use fresh, clean fuel that is purchased in a quantity that can be

used within approximately 30 days, or add fuel stabilizer.

Fuel is blended to give best seasonal performance. To avoid engine

performance problems such as hard starting or vapor lock, use in-season

fuel. Use fuel during warm weather that was purchased during that

season, and use fuel during cold weather that was purchased during that

season.

Fuel can become stale in machines with engines that are used seasonally

or infrequently during a season. Stale fuel can produce varnish and plug

carburetor components which can affect engine performance.

Keep fuel storage container tightly covered and in a cool area out of direct

sunlight. Fuel can break down and degrade if not sealed properly or

exposed to sun and heat.

Condensation may collect in the fuel tank because of a variety of operating

or environmental conditions and, over time, may affect your machine’s

operation. Fill fuel tank at the end of daily use and store fuel in plastic

containers to reduce condensation.

For best year-round performance and fuel-handling, add stabilizer to fuel

IMPORTANT: Avoid damage! Electric charge from booster battery

can damage machine components. Do not install negative

booster cable to machine frame. Install only to the engine block.

Install negative booster cable away from moving parts in the

engine compartment, such as belts and fan blades.
