California Fuel

If your vehicle is certiﬁed to meet California Emission

Standards, it is designed to operate on fuels that

meet California speciﬁcations. See the underhood

emission control label. If this fuel is not available

in states adopting California emissions standards, your

vehicle will operate satisfactorily on fuels meeting

federal speciﬁcations, but emission control system

performance may be affected. The malfunction indicator

lamp may turn on and your vehicle may fail a

smog-check test. See Malfunction Indicator Lamp on

page 3-28. If this occurs, return to your authorized

GM dealer for diagnosis. If it is determined that

the condition is caused by the type of fuel used, repairs

may not be covered by your warranty.

Additives

To provide cleaner air, all gasolines in the United States

are now required to contain additives that will help

prevent engine and fuel system deposits from forming,

allowing your emission control system to work properly. In

most cases, you should not have to add anything to your

fuel. However, some gasolines contain only the minimum

amount of additive required to meet U.S. Environmental

Protection Agency regulations. General Motors

recommends that you buy gasolines that are advertised

to help keep fuel injectors and intake valves clean. If your

vehicle experiences problems due to dirty injectors or

valves, try a different brand of gasoline. Also, your

GM dealer has additives that will help correct and prevent

most deposit-related problems.

Gasolines containing oxygenates, such as ethers and

ethanol, and reformulated gasolines may be available in

your area to contribute to clean air. General Motors

recommends that you use these gasolines, particularly if

they comply with the speciﬁcations described earlier.
