Interesting... yeah, mine's still 60-65psi on hot idle. It does fluctuate a little bit when you push the gas initially, but it doesn't go up any higher than approx. 70psi. Once you push the gas a little bit to start moving, it goes right up to 70 and stays there all the way up to 4,000+ rpms. I know Mobil 1 HM 10W-30 is on the thicker end of the 30-grade spectrum, so I figured the oil pressure would be a little high, but I'm still not sure if the oversized oil filter I put on it would affect it in any way. I really wish I would've paid attention to it when the previous fill from the dealership was in there (AC Delco 5W-30/PF47). One thing I've noticed that may or may not be related is that when you first start the engine cold, I get a bit of what sounds like piston slap for the first 10-15 seconds then it goes away. It lasts longer than the typical rattle one would get from a car building up oil pressure from the filter for a second or two for the oil light to go off, IMO... the oil light isn't on that whole time, either.
