Mobil 1 filters are a microglass/cellulose blend filter which is vastly superior to cellulose only but as in the chain with the weakest link, we are still stuck with the deficiencies of paper. Mobil, as with Amsoil, do not actually manufacture the filters they market, so are beholding to the manufacturer's filter medium capabilities and use. Since Champion is not currently manufacturing any full synthetic automotive/truck medium filters, neither will Mobil. But if a market for very high quality synthetic medium develops, then I am sure Mobil/Champion will move forward to begin marketing them.
This nano-fiber (these names!) *Looks* good but the "rest of the story" will be in its performance numbers... Which I am most anxious to see; I should have my 1,500 miles on by early next week. And yes, I will share all of my results.
Again, I am NOT an Amsoil distributor nor have any affiliation with Amsoil. But if there is a better oil filter, it makes no difference to me who makes it... I will use it...
