Jarrid,
You are a technical guy and ought to appreciate the question about "verifiable data". I this case, that would mean credible drainback measurements comparing Fram, Wix, Purolator and Napa filters.
Not disagreeing with your observation / opinion, just asking if there is verifiable data to support the blanket statement that Fram filters have inadequate drainback valves.
