Mgelchamiescalder, I just checked your owners manual and found some helpful oil information for you! Page 6-14 states the following details regarding the recommended engine oil for your model year.
"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. 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
You should also use the proper viscosity oil for your vehicle, as shown in the chart [on page 6-14 of your owners manual].
As in the chart shown previously, SAE 5W-30 is best for your vehicle. However, you can use SAE 10W-30 if it’s going to be 0F (-18C) or above. These numbers on an
oil container show its viscosity, or thickness. Do not use other viscosity oils, such as SAE 20W-50."
