When to Add Engine Oil
If the oil is below the cross-hatched area at the tip of the
dipstick, add at least one quart/liter of the recommended
oil. This section explains what kind of oil to use. For
engine oil crankcase capacity, seeCapacities and
Specifications on page 5-126.
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.SeeEngine Compartment
Overview on page 5-16
for the location of the
engine oil ll cap.
Be sure to add enough oil to put the level somewhere in
the proper operating range. Push the dipstick all the
way back in when you are through.
