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
GM dealer for service.
To
provide cleaner ail-, 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.
I
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.
