When to Add Engine Oil
If the oil is below the cross-hatched
area at the tip of the dipstick, add
at least one liter/quart of the
recommended oil. This section
explains what kind of oil to use. For
engine oil crankcase capacity, see
Capacities and Specifications
on
page 11‑2
.
Notice: Do not add too much oil.
If the engine has so much oil
that the oil level gets above the
cross-hatched area 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 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. These numbers on an
oil container show its viscosity,
or thickness. Do not use other
viscosity oils such as
SAE 20W-50.
