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.

Notice: Your vehicle was not designed for fuel that

contains methanol. Do not use fuel containing

methanol. It can corrode metal parts in your fuel

system and also damage the plastic and rubber

parts. That damage would not be covered under

your warranty.

Some gasolines that are not reformulated for low

emissions may contain an octane-enhancing additive

called methylcyclopentadienyl manganese tricarbonyl

(MMT); ask the attendant where you buy gasoline

whether the fuel contains MMT. General Motors

recommends against the use of such gasolines. Fuels

containing MMT can reduce the life of spark plugs

and the performance of the emission control system may

be affected. The malfunction indicator lamp may turn

on. If this occurs, return to your authorized GM dealer

for service.

Fuel E85 (85% Ethanol)

The 8th digit of your vehicle identiﬁcation number (VIN)

shows the code letter or number that identiﬁes your

engine. You will ﬁnd the VIN at the top left of the

instrument panel. See Vehicle Identiﬁcation

Number (VIN) on page 5-91.

If your vehicle has the 3.5L V6 engine (VIN Code K

only), you may use either regular unleaded gasoline or

ethanol fuel containing up to 85% ethanol (E85);

also see Fuel on page 5-4. In all other engines, including

the 3.5L V6 (VIN Code N), use only regular unleaded

gasoline.
