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
part 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.
Just 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.
What Kind of Oil to Use
Oils of the proper quality for your vehicle can be
identified by looking for the "Starburst" symbol. The
"Starburst" symbol indicates that the oil has been
certified by the American Petroleum Institute (API), and
is preferred for use in your gasoline engine.
If you change your own oil, be sure you use oil that has
the "Starburst" symbol on the front of the oil container.
If you have your oil changed for you, be sure the oil put
into your engine is American Petroleum Institute
certified for gasoline engines.
You should also use the proper viscosity oil for your
vehicle, as shown in the following chart:
6-11
