The dealer changed my oil, and I asked to get the filter back to open it up. The hole in the end near the lot number is where the mechanic put a hole to drain the filter. It looked good up to a certain point, then I discovered a tear in the media near the cap. The oil was Valv Syn Power. I didn't think 4k was a lot of miles, but having heard so much about the P1 I wanted to take it off and take a look inside. I didn't like what I found. Also, I cut the base plate in half and found some sort of thick gunky stuff around it. Didn't care for that either. This is a new truck practically. Not happy with the Syn Power or the P1.
