When to Add Engine Oil
If the oil is at or below the cross-hatched area at the dip
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 Specifications on page 5- 104.
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.
