6-13When 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 ªCapacities and
Specificationsº 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 that shows the proper
operating range, your engine could be damaged. Your vehicle may have an engine oil fill cap with text
and a graphic or just a graphic as shown.
The engine oil fill cap is located on the valve cover on
the passenger's side of the vehicle. See ªEngine
Compartment Overviewº in the Index for further
location information.
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.
