Although it depends a little bit on where in the world you live I would suggest that a good quality 10W40 will do just fine. Some will tell you that a 5W30 is better and it might be if you live in a cold climate. Just use a broad multi viscosity oil and you'll be fine. I would stay away from single viscosity oils such as 30 weight or 50 weight. The MOST important thing is to change your oil and filter every 3000 miles or less.
