When to Add Engine Oil
If the oil is below the MIN (minimum)
mark, add at least one quart/liter of
the recommended oil. This section
explains what kind of oil to use.
For engine oil crankcase capacity,
see Capacities and Specifications on
page 10-2.
Notice: Do not add too much oil.
If the engine has so much oil
that the oil level gets above the
upper mark that shows the proper
operating range, the engine
could be damaged.
See Engine Compartment Overview
on page 9-6 for the location of
the engine oil fill cap.
Add enough oil to put the level
somewhere in the proper operating
range. Push the dipstick all the
way back in when you are through.
What Kind of Engine Oil to Use
Look for three things:
• GM6094M
Use only an oil that meets
GM Standard GM6094M.
• SAE 5W-30
SAE 5W-30 is best for the
vehicle. If you are in an area
of extreme cold, where the
temperature falls below
−20°F (−29°C), 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.
These numbers on an oil
container show its viscosity, or
thickness. Do not use other
viscosity oils such as
SAE 20W-50.
