DO NOT USE SAE 2OW-50 OR ANY OTHER GRADE OIL NOT RECOMMENDED
As shown in the chat, SAE 5W-30 is b.est for your
vehicle. However, you can use
SAE low-30 if it’s going
to be
0°F (- 18 “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.

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)’ considerusing 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.
