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.
