When To Add Engine Oil - Pontiac 2001 Aztek Owner's Manual

Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don't, the oil dipstick
might not show the actual level.
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.

When to Add Engine Oil

If the oil is at or below the ADD mark, then you'll need
to add at least one quart of oil. But you must use the
right kind. This part explains what kind of oil to use. For
crankcase capacity, see "Capacities and Specifications"
in the Index.
6-12
NOTICE:
Don't add too much oil. If your engine has
so much oil that the oil level gets above the
-
cross hatched area that shows the proper
operating range, your engine could be damaged.
See "Engine Compartment Overview" in the Index for
more information on location.
Be sure to fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back in when you're through.
The engine oil fill cap is
located just behind the
engine oil dipstick.
