TYPE OF FUEL TO USE
• Use clean, fresh, regular unleaded gasoline with a minimum of 85

Emission Control System: EM (Engine Modifications).
CAUTION: Some fuels, called oxygenated or reformulated
gasoline, are gasoline blended with alcohols or ethers.
Excessive amounts of these blends can damage the fuel
system or cause performance problems. If any undesirable
operating symptoms occur, use gasoline with a lower percent-
age of alcohol or ether.
