Since coming here and doing more research I’ve switched to Wix brand oil filters. I know there are probably ones that are a lot better but this one works for me. However I see a couple different versions now. I will link to them but the only difference I see is the height and gallon per minute that can flow. Is the higher flow rate ok to run in a standard slant?

Also it’s a 78 d100 slant of course.

They don't list the micron rating of the second filter (racing). The flow rate is much higher, and that is probably due to decreased filtering. Also the second filter does not have antidrainback, or bypass valves. For normal everyday use I would use the 1st filter (51068)
