Quote: WIX, Fram, NAPA, etc... All of them utilize paper filter media. The manufacturing of paper filter media is not exact. As much as 40% of the filtering area of paper oil filters filter nothing at all, as in the filter is 40% blocked right out of the box.
Plus, how does paper respond to moisture? Right, it absorbs it. What does paper filter media do when it absorbs moisture from engine condensation and then it gets really cold outside. Yep! It freezes. Now your paper filter that was 40% blocked when new is now frozen and is really blocked. Now you have a completely worthless oil filter that's in bypass mode at cold engine start-up until it thaws out.
Do yourself a favor, do your engine a favor and throw out the paper oil filter. Then look for a micro-glass or better yet, a nano-glass oil filter. Previously only available in commercial and industrial applications, glass filter media technology has made it's way to the car and light truck market.
