5W30 or 10W30. If you change your oil every 3,000 miles, it doesn't matter the brand. Most people will tell you synthetic or high mileage oil but if you aren't having any problems with oil burning and your engine runs fine, stick with any brand. Pennzoil doesn't hurt. Over 80% of brand new cars come from the factory with Pennzoil in them. The oils maybe badged with the vehicle manufacturer's name but it's usually Pennzoil. However, if you go over 5,000 miles between changes and you go through severe driving conditions, I would say consider synthetic.
