personally i like oil filters that have good flow i like the classics or even the ones we have here in the shop group 7 also made by purolater i think the p1 is a little restrictive and my oil guage agrees
reason i chose mid grade is because im doing 3k oci for severe duty use. It will be used with formula shell synthetic 5w30. I ruled out rp m1 bdp k&n amsoil fram xg due to price and there meant for long oci i figured mid grade would be best for me. I guess i should be asking which flows the best.

What kind of vehicle you got? Can you elaborate on the oil gauge readings? You talking about reduced max seen oil pressure at high RPM? At idle and low RPM (any time the pump is not in relief), the oil pressure should be the same with any of those filters. That's how my car behaves ... never see any oil pressure difference while using WIX/NAPA Gold, Amsoil, ACDelco, Purolator.

I would call those mid-grade filters, based on price. Around here, they're about 5 to 7 bucks or so.

Wouldnt most filters fall into that category? Seems like the low end would be ecores and OCOD's.
I think any of the OP's mentioned choices are fine options for the high-end of 'mid-grade' options. I'd personally try the P1/BP or NG/Wix. If the P1 is 'restrictive', it's more of a wives tale IMO. Any filter that filters insanely good will have 'restriction' compared to a less efficient filter, in general. Not always the case. Enough to matter? Depends on the application, but I say for street and sane driving no. IMO, the P1 thing could easily apply to any heavy/thick media oil filter. It's more of a concern with racing, but if you're still OCD get the NapaGold/Wix.
I'm trying a P1 on my VX next after using the NG/Wix for a while. I use either interchangeably, FWIW.

ALL will flow just fine the in block by pass will insure that so oil starvation worries should be nil , pick any you mentioned in your opening post and go!
