Although I cannot prove it, my humble opinion is that air filtration is more of a player in many suspect UOA's I have read here, than a poor oil filter choice.
Really, how many people who are savvy enough to pay for a UOA, which your average Joe does not do, is even using a low quality oil filter? The majority of your folks here are using:
1. Napa/Wix
2. Pure One
3. Purolator Premium Plus
4. EA series
5. M1 extended perf.
6. Misc. OEM oil filters
I know we nitpick here, but aren't all the filters I listed in above all good quality filters that will ALL enable one's engine to run a long time if changed within the intervals for which they were designed?
As far as air filtration goes, how many filters are of poor quality and how many skew UOA's as a result of not being sealed correctly, vacuumed or blown out improperly, etc?
