Some gasolines that are not reformulated for low
emissions contain
an
octane-enhancing additive called
methylcyclopentadienyl manganese tricarbonyl (MMT);
ask
your service station operator whether or
not
his
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
help clean
the
air. General Motors recommends that you
use these gasolines 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.
