Fuel: Service Precautions

FUEL USAGE STATEMENT

CAUTION: Using leaded gasoline in this car will damage the catalytic converters and heated oxygen sensors, and affect the warranty coverage validity.

[Except vehicles for MIVEC engine]
Unleaded gasoline having an octane number of 87 [(MON+RON)/2], or 91 RON may be used, though it recommended your vehicle be operated on premium grade unleaded gasoline having a minimum octane number of 91 [(MON+RON)/2], or 95 RON.
To get maximum performance, premium gasoline is recommended.

^ MON: Motor Octane Number
^ RON: Research Octane Number

[Vehicles for MIVEC engine]
Your vehicle is designed to operate on premium grade unleaded gasoline having a minimum octane number of 91 [(MON+RON)/2], or 95 RON. If premium grade unleaded gasoline is not available, unleaded gasoline having an octane number of 87 [(MON+RON)/2] or 91 RON may be used. However, the performance level may be reduced.

GASOLINE CONTAINING ALCOHOL
Some gasoline sold at service stations contain alcohol although they may not be so identified. Using fuels containing alcohol is not recommended unless the nature of the blend can be determined as being satisfactory.
Gasohol: A mixture of 10% ethanol (grain alcohol) and 90% unleaded gasoline may be used in your vehicle. If driveability problems are experienced as a result of using gasohol, it is recommended that the vehicle be operated on gasoline.
Methanol: Do not use gasoline containing methanol (wood alcohol). Using this type of alcohol can result in vehicle performance deterioration and damage critical parts in the fuel system components. Fuel system damage and performance problems resulting from the use of gasoline containing methanol may not be covered by the new vehicle warranty.

GASOLINE CONTAINING METHYL TERTIARY BUTYL ETHER (MTBE)
Unleaded gasoline containing 15% or less MTBE may be used in your vehicle. (Fuel containing MTBE over 15% in volume may cause reduced engine performance and produce vapor lock or hard starting.

MATERIALS ADDED TO FUEL
Indiscriminate use of fuel system cleaning agents should be avoided. Many materials intended for gum and varnish removal may contain highly active solvents or similar ingredients that can be harmful to gasket and diaphragm materials used in fuel system component parts.
