Downloaded from www.Manualslib.com manuals search engine Oil Pressure Gage
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 problem causing low
oil pressure. Check your oil as soon as possible.
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.
I NOTICE:
Damage to your engine from neglected oil
problems can be costly and is not covered by
your warranty.

The engine oil filler cap is located between the air
cleaner and engine oil dipstick.
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. 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
-.
I I 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 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
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.
