Fuel Recommendations

WARNING

Explosive Fuel can cause res

and severe burns.

Donotllthefueltankwhilethe

engine is hot or running.

Gasoline is extremely ammable and its vapors can explode

if ignited. Store gasoline only in approved containers, in

well ventilated, unoccupied buildings, away from sparks or

ames. Do not ll the fuel tank while the engine is hot or

running, since spilled fuel could ignite if it comes in contact

with hot parts or sparks from ignition. Do not start the

engine near spilled fuel. Never use gasoline as a cleaning

agent.

General Recommendations

Purchase gasoline in small quantities and store

in clean, approved containers. A container with a

capacityof2gallonsorlesswithapouringspoutis

recommended.Suchacontaineriseasiertohandleand

helps eliminate spillage during refueling.

Donotusegasolineleoverfromthepreviousseason,

to minimize gum deposits in your fuel system and to

ensure easy starting.

Do not add oil to the gasoline.

Donotoverllthefueltank.Leaveroomforthefuelto

Fuel Type

For best results use only clean, fresh, unleaded gasoline

withapumpstickeroctaneratingof87orhigher.In

countries using the Research method, it should be 90

octane minimum.

Unleaded gasoline is recommended as it leaves

less combustion chamber deposits and reduces

harmful exhaust emissions. Leaded gasoline is not

recommended.

Gasoline/Alcohol blends

Gasohol (up to 10% ethyl alcohol, 90% unleaded

gasolinebyvolume)isapprovedasafuelforKohler
