WEATHER
DO NOT USE SAE 2OW-56 OR ANY OTHER
GRADE OIL NOT RECOMMENDED
As shown in the chart, 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 SAE 20W-50.
ITICE
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
"Starburst" symbol. Failure to use the proper oil
can result in engine damage not covered by your
warranty.
GM Goodwrench@ oil (in Canada, GM Engine Oil)
meets all the requirements for your vehicle.
