What Kind of Engine Oil to Use
Recommended SAE viscosity grade

1506679
Look for two things:
GM6094M
Your vehicle’s engine requires oil meet-
ing standard GM6094M. Look for and
use only an oil that meets standard
GM6094M.
SAE 5W-30
As shown in the viscosity chart, SAE
5W-30 is best for your vehicle.
These numbers on an oil container show
its viscosity, or thickness. Do not use
other viscosity oils such as SAE 20W-
50.
808500
Oils meeting these requirements should
also have the starburst symbol on the con-
tainer. This symbol indicates that the oil
has been certified by the American Petro-
leum Institute (API).
Look for this information on the oil con-
tainer, and use only those oils that are
identified as meeting standard GM6094M
and have the starburst symbol on the front
of the oil container.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.
Engine Oil Additives
Do not add anything to the oil. The recom-
mended oils with the starburst symbol that
meet standard GM6094M are all you need
for good performance and engine protec-
tion.
Engine Oil Life SystemWhen to Change Engine Oil
Your vehicle has a computer system that
lets you know when to change the engine
oil and filter. This is based on engine revo-
lutions and engine temperature, and not on
mileage. Based on driving conditions, the
mileage at which an oil change will be indi-
cated can vary considerably. For the oil life
