DO NOT
USE SAE 2OW-50 OR ANY
OTHER GRADE OIL NOT RECOMMENDED
As
shown in the chart, if you nave the 3800 engine,
SAE 1OW-30 is best for your vehicle. However, you
can use
SAE
5W-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
S A E
2OW-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 S A E OW-30 oil. Both will provide
easier cold starting and better protection for your engine
at extremely low temperatures.
