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.

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)’ 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.

NOTICE:
When adding. coolant, It is important that you use
