Engine Oil
It's a good idea to check your engine oil
every time you get fuel. In order to get
an accurate reading, the oil must be
warm and the vehicle must be on level
ground. 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.
To Check 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 lower.

When to Add Oil:
If the oil is at or below the
ADD
line,
then you'll need to add some oil. But
you must use the right kind. This
section explains what kind of oil to use.
