GM Goodwrench oil meets all the requirements
for your vehicle.
If you are in an area of extreme cold, where the
temperature falls below −20°F (−29°C), it is
recommended that you use either an SAE 5W-30
synthetic oil or an SAE 0W-30 oil. Both provide
easier cold starting and better protection for
the engine at extremely low temperatures.

Look for two things:
•
GM4718M
Your vehicle's engine requires a special oil
meeting GM Standard GM4718M, such
®
as Mobil 1 or equivalent. Oils meeting this
standard may be identified as synthetic.
However, not all synthetic oils will meet this
GM standard. Look for and use only an oil that
meets GM Standard GM4718M.
