I'd be of the persuasion that Amsoil and Champion Labs will solve the problem, with publicity at stake, solutions usually happen.
NAPA has changed suppliers a few times, no more Wix/Mann-Hummel but now Asian made. Many "name brands" are made by XYZ these days.Always name brand though never store brands unless it’s Napa. Nothing wrong with those filters but I prefer name brand.
PurolatorNot looking to start a war on what filter is BEST. I just would like to know what brand everyone uses for their own vehicles as I am now changing oil on my brand new corvette and a 22 diesel Tahoe. What brands do you guys like consistently?
