OIL 0-
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 (kilopascals).
Oil pressure may vary with engine speed, outside
temperature
and oil viscosity, but readings above the
low pressure zone indicate the normal operating range.
A reading in the low pressure zone may be caused by a
dangerously
low oil level or other problems causing low
oil pressure.
CAUTION:
Don't keep driving if the oil pressure is low. If
you do, your engine can become so hot that it
catches fire. You or others could be burned.
Check your oil as soon as possible and have your
vehicle serviced.
NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

NOTICE:
. Don’t-add too much oil. If your engine has so
much oil that the oil level gets above the
cross-hatched area that shows the proper
operating range, your engine could be damaged.
Just fill i.t 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 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.
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 2OW-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 IOW-30 if it’s going
to be
0°F (- 1 SOC) 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 recommended oil can result in engine damage not
covered by your warranty.
GM Goodwrench@ oil meets all the requirements for
your vehicle.
Engine Oil Additives
Don’t add anything to your oil. Your GM dealer is ready
to advise if you think something should be added.
