When To Add Engine Oil - GMC SIERRA DENALI 2002 Manual

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 engine oil crankcase capacity, see "Capacities and
Specifications" in the Index.
NOTICE:
Don't add too much oil. If your engine has so
much oil that the oil level gets above the
-
cross hatched area upper mark 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 on the passenger's
side valve cover.
