My point in sharing the comment made by someone was - Champion Laboratories makes filters for K & N, Mobil 1, AC Delco, Super Tech, STP & probably several more or less known names.
If you just search "who makes K & N oil filters", Champion Laboratories name comes up. Likewise, the warranty for Mobll 1 is handled by Champion Laboratories (like you just shared).
These various oil filters are not created the same, however. I'm sure Mobil 1 is one of the better ones! I like the fact that Mobil 1 pretty much offers one filter. The M1-110A has sort of replaced the M1-110, which makes sense. It would be silly to offer a 20,000 mile Mobil 1 synthetic oil without an oil filter to go with it.
Personally, none of these high mileage claims means anything to me. Recommended oil change intervals are 3,750 or 7,500 miles depending on your driving circumstances, & no oil or filter claim supersedes that.
If you like doing your shopping @ Walmart, the Mobil 1 and Fram Ultra Synthetic oil filters are probably the best two picks.
