Turn off the engine and give the oil several minutes to
drain back into the oil pan. If you don’t, the oil
dipstick might not show the actual level.
Pull out the dipstick and clean it with a paper towel or
cloth, then push it back in all the way. Remove it again,
keeping the tip down, and check the level.
When to Add Engine Oil
If the oil is at or below the 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, seeCapacities and Specifications
on page 5-92.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 oilfill cap is
located toward the front of
the engine near the
yellow-looped engine oil
dipstick handle. See
Engine Compartment
Overview on page 5-10for
more information on
location.
Be sure tofill 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.
