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 and/or your vehicle
may fail a smog-check test. If this occurs, return to your
authorized Buick dealer 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.
In Canada, some gasolines contain an octane enhancing
additive called MMT. If such fuels are used, your
emission control system performance may be affected.
The malfunction indicator lamp on your instrument
panel may also
turn on. If this occurs, return
to
your
authorized Buick dealer for service.
To provide cleaner air, all gasolines 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.
