oil viscosity OLDSMOBILE SILHOUETTE 1997 Owners Manual

The engine oil fill cap is
located just behind the
engine oil dipstick.
Just
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 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 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.
