The owner's manual says 6 months and no more than 6,000 miles. If you were to have a warranty claim on your engine, you would have to provide proof of timely oil changes. That is my fear since I went 7700 miles in a few months. I'll stick to 6,000 with Mobil 1. That will be 3-4 oil changes a year for me.
IMHO a regular filter is OK, PureOne, K&N or Mobil 1 oil filters might be better but there are plenty of opinions on that subject. It is really about the dirt and combustion by-products, whether or not they get trapped and how well the oil disperses or suspends it. I have already had a regular Purolator and a couple of PureOnes. Currently PureOne. Between $5-6 if I remember right.
