Adding Equipment to the Outside of
Your Vehicle
Things you might add to th'e outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your Pontiac dealer before adding equipment to the
outside of your vehicle.
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
cou1.d 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 o'r higher and you
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 your instrument panel
may
t u r n
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 fadure. 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
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
may turn on. If this occurs, return to your authorized
Pontiac dealer for service.
