When to Add Engine Oil
If the oil is at or below the ADD line, 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 Specification
Charts on page 5-38.
Notice: Do not add too much oil. If your engine has
so much oil that the oil level gets above the F
mark that shows the proper operating range, your
engine could be damaged.
The engine oil fill cap is
located near the center of
the engine compartment.
See Engine Compartment
Overview on page 5-14
for more information on its
location.
Be sure to fill it enough to put the level somewhere in
the proper operating range. Push the dipstick all the way
back in when you’re through.
