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 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. 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: 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.
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 may be affected. The malfunction
indicator lamp may turn on. If this occurs, return to
your dealer for service.
