Actually mitchell I think the 10w30 oil is probably the recommended oil for your engine although it's unlikely you'll do any harm by using a 10w40. Check the recommendation in your owners manual (check with the dealer if you don't have one) and follow that whenever possible, but a 10w30 should be fine. Good luck.

5W30 is what is recomended.
5-30 only. For city driving I'd go to synthetic oil.
