Engine Oil (Gasoline Engine)
If your vehicle has a diesel engine, see “Engine Oil
(Diesel Engine)” in the Diesel Engine Supplement.
It’s a good idea to check your engine oil every time
you
get fuel. In order to get an accurate reading, the oil must
be warm and
the vehicle must be on level ground.
Turn off the engine and give
the oil a few minutes to
drain back into the oil
pan.
If you don’t, the oil
dipstick might not show
the actual level.

Downloaded from www.Manualslib.com manuals search engine Checking Engine Oil
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
When to Add Oil
If the oil is at or below the ADD mark, then you’ll need
to add at least one quart
of oil. But you must use the
right kind. This part explains what kind
of oil to use. For
crankcase capacity, see “Capacities and Specifications”
in the Index.
I NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.

Downloaded from www.Manualslib.com manuals search engine What Kind of Oil to Use
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:

Downloaded from www.Manualslib.com manuals search engine I RECOMMENDED SAE VISCOSITY GRADE ENGINE OILS
FOR BEST FUEL ECONOMY AND COLD STARTING, SELECT THE LOWEST
SAE VISCOSITY
GRADE OIL FOR THE EXPECTED TEMPERATURE RANGE.
HOT
WEATHER
I- SAL 1OW-30
SAE SW-30 PREFERRED
.. -.-/
COLD
WEATHER
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.
