GRADE OIL NOT RECOMMENDED
As shown in the chart, SAE 5W-30 is best for your
vehicle. However, you can use SAE low-30 if it's going
to be 0°F
(- 18 "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.
NOTICE:
Use only engine oil with the American Petroleum
Institute Certified For Gasoline Engines
%tarburst" symbol. Failure to use the proper oil
can result in engine damage not covered by your
warranty.

meets all the requirements for your vehicle.
