When to Add Engine Oil
If the oil is below the cross-hatched area at the tip of
the dipstick, you will need to add at least one quart/liter
of oil. But you must use the right kind. This section
explains what kind of oil to use. For engine oil crankcase
capacity, see
Capacities and Specifications on
page 5-90
.
Notice:
Do not add too much oil. If the engine has
so much oil that the oil level gets above the
cross-hatched area that shows the proper operating
range, the engine could be damaged.
See
Engine Compartment
Overview on page 5-12
for
the location of the
engine oil fill cap.
Be sure to add enough oil 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
are through.
