and stop it, then wait at least several min-
utes for the oil to drain back into the crank-
case.

could spurt out. Wait until the oil cools
down before removing the dipstick.
b. Screw the dipstick completely out, and
wipe the dipstick clean, then just rest the
dipstick in the hole.
c. Pull up the dipstick, and check the oil level
whether or not it is between maximum
and minimum level .
d. If the level is lower, add the oil up to the
proper level.
