There are also other oils that meet the spec from Motul, Total, and Amsoil.
Good answer. However your manual should state 0W-30 or 0W-40. The last year or two 5W-30 and 5W-40 have been added.

Mobile 1 0W-40 is your best bet all around--reasonably priced, easy to get, and probably the best oil out of all of them.
