To Check Engine Oil
Turn off the engine
and give the oil a few
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 lower.
When to Add Oil
If the oil is at or below the ADD mark, then you’ll need to add some oil. But
you must use the right kind. This section explains what kind of oil
to use.
For crankcase capacity, see “Capacities and Specifications”
in the Index.
NOTICE:
Don’t add too much oil. If your engine has so much oil that the
oil level gets above the upper mark that shows the proper
operating range, your engine could be damaged.
