I If your vehicle is certified to meet California Emission
j Standards (indicated on the underhood emission control
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
1 vehicle will operate satisfactorily on fuels meeting
federal specifications, but emission control system
1 performance may be affected. The malfunction indicator
lamp on your instrument panel may turn on and/or 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
1 determined that the cause of the condition is the type of
1 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
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 i may turn on. If this occurs, return to your authorized
i 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 forrning
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.
