When to Add Engine Oil
If the oil is at or below the ADD line, 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.
The engine oil fill cap is
located behind the radiator
on the passenger’s side of
the vehicle. For more
information on location, see
“Engine Compartment
Overview” in the Index.
Turn the cap counterclockwise to remove it.
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.
