New guy here, been reading for a looooong time and very impressed with the knowledge base here. My question: last oil change I switched to Fram Ultra oil filter and it changed the oil pressure reading on my gauge. I was running about 30psi at hot idle, now it shows 40psi at hot idle. This is not a high tech engine, Jeep 4.0 in wrangler (02 Sport) and it seems to run fine with whatever oil I have put in it (10w-30). My UOA showed a good report with a recommendation of longer OCI's. The only thing different is the oil filter. Previously I used what I could find on the shelf at wallyworld, usually a FL-A1 or purolater. Thanks for any insight.
