DO NOT USE SAE 2OW.50 OR ANY OTHER
As shown in the chart, if you have the 3800 engine, SAE
low-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
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.
