spark plugs BUICK ENCLAVE 2009 Owner's Manual

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 specications 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 nd. 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.
