1998 PONTIAC GRAND AM oil viscosity

3100 Engine
The 3100 engine oil fill cap is on the front of the engine,
behind
the radiator.
Be sure to fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back in
when you’re through.
What Kind of Engine Oil to Use
Oils recommended for your vehicle can be identified by
looking for the “Starburst” symbol.
This symbol
indicates that the oil has been certified by the American
Petroleum Institute
(API). Do not use any oil which
does not
carry this Starburst symbol.
A
If you change your own oil,
be sure you use oil that has
the Starburst symbol on the
front of the
oil container. If
you have your oil changed
for you, be sure the oil put
into your engine is
American Petroleum
Institute certified for
gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:

GRADE OIL NOT RECOMMENDED
As shown in the chart, SAE 5W-30 is best for your
vehicle. However, you can use
SAE 1OW-30 if it’s going
to
be 0” F (- 18 O C) or above. These numbers on an oil
container show its viscosity, or thickness. Do not use
other viscosity oils, such as SAE 20W-50.
I NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst” symbol. Failure to use the
recommended oil can result in engine damage not
covered by your warranty.
GM Goodwrench@ oil meets all the requirements for
your vehicle.
If you
are in an area where the temperature falls below
-20°F (-29”C), consider using either an
SAE 5W-30
synthetic oil or an
SAE OW-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
