California Fuel

If your vehicle is certiﬁed to meet California Emissions

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 3-35. 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.

To help keep fuel injectors and intake valves clean,

or if your vehicle experiences problems due to

dirty injectors or valves, look for gasoline that is

advertised as TOP TIER Detergent 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. General Motors recommends that you use

these gasolines if they comply with the speciﬁcations

described earlier. However, E85 (85% ethanol)

and other fuels containing more than 10% ethanol must

not be used in vehicles that were not designed for

those fuels.
