As far as oil filters I like Wix (napa gold, Carquest are wix) Purolater filters,
For cheap filters I like Champion labs filters. (WM tech 2000)
I would rather use a roll of toilet paper than a base Extra Guard fram filter. . The higher priced frams are ok.
I have had problems with Fram filters: 1. Oil pressure started acting funny. Pulled off fram filter and found it had came completly apart inside. The filter medimun (What little there is of it) came loose and was floating around inside the can.. 2. The anti backflow valves do not work well allowing the oil in my oil cooler and the rest of the lube system to drain back into the pan giving me dry starts.
IMHO they are very low quality. The only reason they are so popular is they pay Big stores and autoparts chains to only carry their products. Then do heavy marketing.
Do a search google or whatever. There is all kinds of info on frams out there. Many people on other car forums have bad opinions about them
Search the words, Oil filter study. Interesting stuff.
