SAE CW-30 PREFERRED
DO NOT USE SAE 2OW-50 OR ANY OTHER
GRAOE OIL NOT RECOMMENDED
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 (- 1 8 O 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.
I 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.
Engine Oil Additives
Don’t add anything to your oil. Your Oldsmobile retailer is
ready to advise
if you think something should be added.
