1996 PONTIAC FIREBIRD engine

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 Pontiac 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 you use such fuels, your
emission control system performance may deteriorate and the malfunction indicator lamp on your instrument
panel may
turn on. If this happens, return to your
authorized Pontiac 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. Therefme,
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: I
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.

Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible! See “Cleaning the
Outside
of Your Pontiac” in the Index.
When
you plat the cap back on, turn it to the right until
you hear at least three clicks. Make sure you fully install
the cap. The diagnostic system can determine if the fuel
cap
has been left of or improperly installed. This would
allow fuel to evaporate into
the atmosphere. See
“Malfunction Indicator
Lamp” in the Index.
NOTICE:
If you need a new cap, be sure to get the right
type. Your dealer can get one for you, If you get
the
wrong type, it may not fit and your fuel tank
and emissions system might
be damaged.
