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. 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.

Fuels in Foreign

Countries

If you plan on driving in another

country outside the United States or

Canada, the proper fuel might be

hard to ﬁnd. Never use leaded

gasoline or any other fuel not

recommended in the previous text

on fuel. Costly repairs caused

by use of improper fuel would not

be covered by the vehicle warranty.

To check the fuel availability, ask

an auto club, or contact a major

oil company that does business

in the country where you will

be driving.
