A CAUTION:
You can be injured and your vehicle could be
damaged if you try to do service work on a
vehicle without knowing enough about it.
Be sure you have sufficient knowledge,
experience, and the proper replacement
parts and tools before you attempt any
vehicle maintenance task.
Be sure to use the proper nuts, bolts and
other fasteners. “English” and “metric”
fasteners can be easily confused. If
you use
the wrong fasteners, parts can later break
or fall off. You could be hurt.

Fuel
Use regular unleaded gasoline rated at 87 octane or
higher.
At a minimum, it should meet specifications
ASTM D4814 in the United States and CGSB 3.5-M93
in Canada. Improved gasoline specifications have been
developed by the American Automobile Manufacturers
Association
(AAMA) for better vehicle performance
and engine protection. Gasolines meeting the AAMA specification could provide improved driveability and
emission control system protection compared to other
gasolines.
Be ,sure the posted octane
is at least 87. If the octane-is
less
than 87, you may get a heavy knocking noise when
you drive. If it’s bad enough, it can damage your engine.
If you’re using fuel rated at 87 octane or higher and you
still hear heavy knocking, your’engine needs service.
But don’t worry if you hear a little pinging noise when
you’re accelerating
or driving up a hill. That’s normal,
and you don’t have to buy a higher octane fuel to get rid
of pinging. It’s the heavy, constant knock that means
you have a problem.
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
you 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
sf 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. 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.
Fuels in Foreign Countries
If you plan on driving in another country outside the
United States or Canada, the proper fuel may be hard to
find. Never use leaded gasoline
or any other fuel not
recommended in the previous text on fuel. Costly repairs
caused by use of improper fuel wouldn’t be covered by
your warranty.
To check on fuel availability, ask an auto club, or
contact a major oil company .that does business
in the
country where you’ll be driving.
