When to Add Engine Oil
If the oil is at or below the MIN mark for the 2.2L L4
ECOTEC™ engine or below the cross-hatched area at
the tip of the dipstick for the 3400 V6 engine, then
you will need to add at least one quart of oil. But you
must use the right kind. This section explains what kind
of oil to use. For engine oil crankcase capacity, see
Capacities and Specifications on page 5-95.
Notice: Do not add too much oil. If your engine has
so much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.
See Engine Compartment
Overview on page 5-12 for
the location of the
engine oil fill cap.
Be sure to 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 two things:
• GM6094M
Your vehicle’s engine requires oil meeting GM
Standard GM6094M. You should look for and use
only an oil that meets GM Standard GM6094M.
