Synthetic Oil

You may use a synthetic motor oil if
it meets the same requirements
given for a conventional motor oil: it
displays the API certification seal,
and it is the proper weight. You must
follow the oil and filter change
intervals shown on the information
display.

Engine Oil Additives

Your vehicle does not require any oil
additives. Additives may adversely
affect the engine or transmission
performance and durability.
