Oil Pressure Gage
SERVICE
ENGINE
SOON
The oil pressure gage shows the engine oil pressure in
psi (pounds per square inch) when the engine is running.
Canadian vehicles indicate pressure in kPa. Oil pressure
may vary with engine speed, outside temperature and oil
viscosity, but readings above the red warning zone
indicate the normal operating range.
A reading in the red zone may be caused by a
dangerously low oil level or other problem causing low
oil pressure. Have your vehicle serviced immediately.
NOTICE:
Damage to your engine from neglected oil
problems Can be costly and is' nat covered by your
warranty.

What Kind of Oil to Use
Oils of the proper quality for your vehicle can be
identified by looking for the “Starburst” symbol. The
“Starburst” symbol indicates that the oil has been
certified by the American Petroleum Institute
(API), and
is preferred for use in your gasoline engine.
Beginning midyear 1993, oils of the proper quality for
your vehicle will be identified with this
new “starburst”
symbol. The “starburst” symbol indicates that the oil has
been certified by the American Petroleum Institute
(MI), and is preferred for use in your gasoline engine.
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:

DO NOT USE SAE ZOW-50 OR ANY OTHER 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°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.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
“Starburst” symbol. Failure to use the proper oil
can result in engine damage not covered by your
warranty.
GM Goodwrench’ oil (in Canada, GM Engine Oil)
meets all the requirements for your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your Pontiac dealer is
ready to advise if you think something should be added.
