When to Add Engine Oil
If the oil is at or below the cross-hatched area at the tip
of the dipstick, 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 Speci®cations on
page 5-92.
See ªRacing or Other Competitive Drivingº under
Starting Your Engine on page 2-21for additional
information on engine oil.
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.The engine oil ®ll cap is
located in the engine
compartment on top of the
valve cover on the
passenger's side of the
vehicle. See
Engine
Compartment Overview on
page 5-12
for more
information on location.
Be sure to ®ll it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back in when you're through.

Standard designation, you can cause engine
damage not covered by your warranty.
