Checking Engine Oil
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 L (low) mark, 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 crankcase capacity, see "Capacities and
Specifications" in the Index.

NOTICE:

I
Don't add too much oil. If your engine has so
I
much oil that the oil level gets above the upper
mark that shows the proper operating range,
your engine could be damaged.
The engine oil fill cap is located in the rear of the
engine compartment.
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.
