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.
