FUEL REQUIREMENTS
Additives - The use of gasoline containing detergents, corrosion and stability additives is recommended, as these additives will improve fuel economy, reduce emissions, and maintain vehicle performance.

Fuel Quality - Poor quality gasoline can cause problems such as hard starting, stalling, and stumble. If you experience these problems, try another brand of gasoline before considering service for the vehicle.

Pinging/Knocking - Light knock at low engine speeds is not harmful to your engine. However, continued heavy spark knock at high speeds can cause damage and should be reported to your dealer immediately.

CAUTION: Engine damage resulting from operating with a heavy spark knock may not be covered by the new vehicle warranty.

GASOLINE/OXYGENATE BLENDS
Ethanol - (Ethyl or Grain Alcohol) properly blended, is used as a mixture of 10 percent ethanol and 90 percent gasoline. Gasoline blended with ethanol may be used in your vehicle.

Methanol - (Methyl or Wood Alcohol) is used in a variety of concentrations when blended with unleaded gasoline. You may find fuels containing 3 percent or more methanol along with other alcohols called cosolvents.

CAUTION: Do not use gasoline containing Methanol. Use of methanol/gasoline blends may result in starting and driveability problems and damage critical fuel system components. Problems that are the result of using methanol/gasoline blends may not be covered by the new vehicle warranty.

CLEAN AIR GASOLINE
MTBE/ETBE - Many gasoline are now being blended that contribute to cleaner air, especially in those areas of the country where pollution levels are high. These new blends provide a cleaner burning fuel and some are referred to as reformulated gasoline..

MTBE (Methyl Tertiary Butyl Ether) blends are a mixture of unleaded gasoline and up to 15 percent MTBE. Gasoline blended with MTBE may be used in your vehicle.

ETBE (Ethyl Tertiary Butyl Ether) blends are a mixture of unleaded gasoline and up to up to 17 percent ETBE. Gasoline blended with ETBE may be used in your vehicle.

ADDITIVE CAUTION: Many materials intended for gum and varnish removal may contain active solvents or similar ingredients that can be harmful to fuel system gasket and diaphragm materials. Indiscriminate use of fuel system cleaning agents should be avoided.
