Additives

To provide cleaner air, all gasolines in the United States

are now required to contain additives that help prevent

engine and fuel system deposits from forming, allowing

the emission control system to work properly. In most

cases, you should not have to add anything to the 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 the vehicle experiences

problems due to dirty injectors or valves, look for gasoline

that is advertised as TOP TIER Detergent Gasoline.

For customers who do not use TOP TIER Detergent

Gasoline regularly, one bottle of GM Fuel System

Treatment PLUS, added to the fuel tank at every engine

oil change, can help clean deposits from fuel injectors

and intake valves. GM Fuel System Treatment PLUS

is the only gasoline additive recommended by General

Motors.

Also, your dealer/retailer has additives that will help

correct and prevent most deposit-related problems.

Gasolines containing oxygenates, such as ethers and

ethanol, and reformulated gasolines might be available in

your area. We recommend 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: This vehicle was not designed for fuel

that contains methanol. Do not use fuel containing

methanol. It can corrode metal parts in the fuel

system and also damage plastic and rubber parts.

That damage would not be covered under the vehicle

warranty.

Some gasolines that are not reformulated for low

emissions can contain an octane-enhancing additive

called methylcyclopentadienyl manganese tricarbonyl

(MMT); ask the attendant where you buy gasoline

whether the fuel contains MMT. We recommend against

the use of such gasolines. Fuels containing MMT can

reduce the life of spark plugs and the performance

of the emission control system could be affected. The

malfunction indicator lamp might turn on. If this occurs,

return to your dealer/retailer for service.
