If your vehicle is certified to meet California Emission
Standards (indicated on the underhood tune-up label), it
is designed to operate on fuels that meet California
specifications.
If such fuels are not available in states
adopting California emissions standards, your vehicle
will operate satisfactorily on fuels meeting federal
specifications, but emission control system performance
may be affected. The malfunction indicator lamp on
your instrument panel may turn on andor your vehicle
may fail a smog-check test.
If this occurs, return to your
authorized Oldsmobile retailer for diagnosis to
determine the cause of failure.
In the event it is
determined that the cause of the condition is the type
of
fuels used, repairs may not be covered by your warranty.
Some gasolines that are not reformulated for low
emissions contain an octane-enhancing additive called
methylcyclopentadlenyl manganese tricarbonyl
("T);
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
Oldsmobile retailer 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.
