1998 PONTIAC GRAND AM fuel type

If your vehicle is certified to meet California Emission
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
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.
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 aEected. The
malfunction indicator lamp on your instrument panel
may turn on.
If this occurs, return to your authorized
Pontiac dealer
for service.
To provide cleaner air, all gasolines in the United States
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.
I 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.

’ A CAUTION:
If you get gasoline on yourself and then
something ignites it, you could be badly burned.
Gasoline
can spray out on you if you open the
fuel filler cap too quickly.
This spray can happen
if your tank is nearly full, and is more likely in
hot weather. Open the fuel filler cap slowly and
wait for any “hiss” noise to stop. Then unscrew
the cap
all the way.
Be careful not to spill gasoline. Clean gasoline from
painted surfaces as soon as possible. See “Cleaning the
Outside of Your Vehicle” in the Index. When you put the
cap back
on, turn it to the right
(clockwise)
until you hear a clicking sound. Make sure
you
fully install the cap. The diagnostic system can
determine
if the fuel cap has been left off 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 €it properly. This may
cause your malfunction indicator lamp to
light
and your fuel tank and emissions system may be
damaged.
See “Malfunction Indicator Lamp” in
the Index.

NOTICE:
Don’t let anyone tell you that underinflation or
overinflation is all right. It’s not. If your tires
don’t have enough
air (underinflation), you can
get the following:
0 Too much flexing
0 Too much heat
Tire overloading
Bad wear
0 Bad handling
Bad fuel economy.
If your tires have too much air (overinflation),
you can get the following:
Unusual wear
Bad handling
0 Rough ride
0 Needless damage from road hazards.
When
to Check
Check your tires once a month or more.
Don’t forget your compact spare
tire. It should be at
60 psi (420 Wa).
How to Check
Use a good quality pocket-type gage to check tire
pressure. You can’t tell if your tires
are properly inflated
simply by looking at them. Radial tires
may look
properly inflated even when they’re underinflated.
Be sure to put
the valve caps back on the valve
stems. They help prevent leaks by keeping out dirt
and moisture.
Tire Inspection and Rotation
Tires should be rotated every 6,000 to 8,000 miles
(10 000 to 13 000 km). Any time you notice unusual
wear, rotate your tires as soon as possible and check
wheel alignment. Also check for damaged tires or
wheels. See “When It’s Time for New Tires” and
“Wheel Replacement” later
in this section for
more information.
The purpose of regular rotation is to achieve more
uniform wear for all tires on the vehicle. The first
rotation is the most important. See “Scheduled
Maintenance Services” in the Index for scheduled
rotation intervals.
