Some gasolines that are not reformulated for low
emissions may contain an octane

-

enhancing additive

called methylcyclopentadienyl manganese tricarbonyl
(MMT); ask your service station operator whether or 
not the fuel contains MMT. General Motors does not
recommend the use of such gasolines. If fuels containing
MMT are used, spark plug life may be reduced and your
emission control system performance may be affected.
The malfunction indicator lamp on your instrument
panel may turn on. If this occurs, return to your
authorized Buick dealer for service.

To provide cleaner air, all gasolines in the United States
are now required to contain additives that will help
prevent deposits from forming in your engine and fuel
system, allowing your emission control system to
function properly. Therefore, you should not have to 
add anything to the fuel. In addition, gasolines
containing oxygenates, such as ethers and ethanol, and
reformulated gasolines may be available in your area to
contribute to clean air. General Motors recommends 
that you use these gasolines, particularly if they comply
with the specifications described earlier.

NOTICE:

Your vehicle was not designed for fuel that
contains methanol. Don’t use it. It can corrode
metal parts in your fuel system and also damage
plastic and rubber parts. That damage wouldn’t
be covered under your warranty.

Fuels in Foreign Countries

If you plan on driving in another country outside the
United States or Canada, the proper fuel may 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 wouldn’t be covered by
your warranty.

To check on fuel availability, ask an auto club, or
contact a major oil company that does business in 
the country where you’ll be driving.
