REO
As shown in the chart, SAE 5W-30 is best for your
vehicle. However,
you can use SAE low-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.
