As
shown
in
the chart, SAE low-30 is best for your
vehicle. However, you can use SAE SW-30
if
it’s going
to be colder than 60°F
(
16”
C)
before your next oil
change. When it’s very cold, you should use
SAE
5W-30. These numbers on an oil container show its
viscosity, or thickness.
Do
not use other viscosity oils,
such as
SAE
20W-SO.
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 SW-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.
