In reference to the 92 GT in signature. Engine builder recommended Fram HP1 back in 2001. The engine has a high flow oil pump. 10W-40 Royal Purple. I change the oil every 3000 miles(I don't get a chance to drive it very often). Would a "better" filter be an option I should explore? My concern is the high volume oil pump with a different filter(possibly more restriction?) I have an M1 filter should I use it or something else or just stick with the HP1? Thanks for any advice.
