When to Add Engine Oil
If the oil is at or below the cross-hatched area at the tip
of the dipstick, 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 Speci®cations on
page 5-93.
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 near the engine oil
dipstick. 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 in the cross-hatched
area. Push the dipstick all the way back in when you're
through.
