Adding Equipment to the Outside of
Your Vehicle
Things you might add to the outside of your vehicle can
affect the airflow around it. This may cause wind noise
and affect windshield washer performance. Check with
your Oldsmobile retailer 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 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
your instrument panel may turn on and/or your vehicle
may fail
a smog-check test. If this occurs, return to
your authorized Oldsmobile retailer 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
methylcyclopentadlenyl 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
Oldsmobile retailer for service.

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. Ths 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 retailer can get one for you.
If you get
the wrong type,
it may not fit 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.
Checking Things Under the Hood
An electric fan under the hood can start up and
injure you even when the engine is not running.
Keep hands, clothing and tools away from any
underhood electric fan.
1
Things that burn can get on hot engine parts and
start a fire. These include liquids like gasoline,
oil, coolant, brake fluid, windshield washer and
other fluids, and plastic or rubber.
You or others
could be burned. Be careful not to drop or spill
things that will burn onto a hot engine.

Inflation -- Tire Pressure
the driver’s door, shows the correct inflation pressures
me
Certificatioflire label, which is on the rear edge
of
for your tires when they’re cold. “Cold” means your
vehicle has been sitting for at least three hours or driven
no more than 1 mile (1.6 lun).
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:
Too much flexing
Too much heat
0 Tire overloading
0 Bad wear
0 Bad handling
0 Bad fuel economy.
NOTICE: (Continued NOTICE:
(Continued)
If your tires have too much air (overinflation),
you can get the following:
0 Unusual wear
Bad handling
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 kPa).
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.
