i was in an advanced auto yesterday, and bought some purolator fitlers. i saw they had valvoline maxlife oil fitlers, advertising on the box, it can remove up to 50% more sludge. wondering if their filters are nay good, and what their oil flow rate would be? ive found, using bobistheoilguys chart infomation, purolator flowed the best, mobile 1 was in the middle, and fram was poor. where would the maxlife fitler flow be with those 3 examples?
