I called the ford techline and the kid read me the details, he never said micron just 25 "U" I said the "U" means micron, LOL!!!. I am 100% sure it is not 10 microns!!!! Ford is good but they aint that good. Even the best filter on the market IMHO RP has 20 micron at 97% and 25 at 99% single pass. I think the FL-1A is 97% at 25 micron, remember at 4 gpm at 2K rpm it takes about 35 seconds for your entire 9 quarts of
oil to go through the filter, sooo once again single pass is just more misleading advertising, Ok I will take two passes or 70 seconds to get the 100% 25 micron rating.
Heck as the filter gets dirty it gets more efficient!!!
