The engine oil fill cap is located just behind the engine
oil dipstick.
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. Oils
recommended for your vehicle can be identified by
looking for the “Starburst” symbol. This symbol
indicates that the oil has been certified by the American
Petroleum Institute (API).
Do not use any oil which
does not carry this Starburst symbol.
What Kind of Oil to Use
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:

DO NOT
USE SAE 2OW-50 OR ANY OTHER

As shown in the chart, SAE 5W-30 is best for your
vehicle. However, you can use
SAE 1OW-30 if it’s going
to be
0” F (- 18 O C) or above. These numbers on an oil
container show its viscosity, or thickness. Do not use
other viscosity oils, such as
SAE 2OW-50.

recommended oil can result in engine damage not covered by your warranty.
