NOTICE:
Don’t add too much oil. If your engine has so
much oil that the oil level gets above the

The engine oil fill cap is located toward the front of the
engine near the yellow

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.

be sure you use oil that has
the starburst symbol on the

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:
