As for aftermarket oil filters, I've been running the Mobil1 M1-104 with good results.
I'm not especially loyal to M1. I just got an oil+filter deal at a good price. Factory fill sample is in the mail and I plan to get the M1 0W20 analyzed as well. I believe many are seeing high Fe counts (across many engines) with M1, and there's endless debate about this on various forums. Nobody seems to know why. Plan A was a PureOne filter and Pennzoil Platinum, but I had to make do with what was on the shelf.
