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:

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 (- 1 8 O C) or above. These numbers on an oil
container show its viscosity, or thickness.
Do not use
other viscosity oils, such as SAE 20W-50.
