I've used Motorcraft oil filters religiously for over 28 years driving 900,000+ miles, on 4, 6, and 8 cylinder Fords with ZERO issues. And, I change those filters once every 2,000-3,500 miles with the oil. That's normal driving up here on the Tundra (-25F to +105F).
Like Me32, I'm a Motorcraft Lifer!:rockon:
like we've said above nothing at all wrong with a MC filter. they're awesome filters. but there are MUCH better filters out there.
also changing oil at 2500-3500 miles on practically any oil is a waste anymore.
