Well, Im running a PH52 on my 5.7 OBS. I used to have the attitude that 90% of the oils and filters on the shelf were all the same but that compasion chart is starting to change my mind now.
I had the same mentality but I still think spending $10+ on an oil filter is ridiculus. He did a comparisin on which was the best bang for your buck kinda thing in a thread on his site and he said Fram was the best choice but not the regular one I think it was the extended guard or whatever theyre called but was stil almost 8$
