If anyone's interested, I just posted the results of my first UOA on my F-150 with the by-pass filter installed. At first I was worried because of all the posts I read concerning the reduction in flow and drop in pressure that might be linked to this unit but none of this is taking place on my engine. I even went as far as to install a real oil pressure gauge and I'm getting 75 psi at start up and about 40 psi on a hot idle. I bought the truck new and changed the oil at 1k then again at 2.5k and thats when I made the switch to Mobil 1 5w-30 and the by-pass filter. I ended up running that oil for 7300 miles and judging from the report, I changed it too early. I'll now the TBN tomorrow since Blackstone forgot to include it. Well anyway, here's the link:
