MaxHeadroom, you mention the Fram Ultra, and other, filters as good - do you think they are better than the Mobil 1 Synthetic filter? It often comes with the oil in an "oil change special".
Fram Ultra is better than even the latest version of the Mobil 1 synthetic oil filter.
The reasons why: Mobil 1 Synthetic oil filter is really using only about half synthetic (glass fibers) media, and half cellulose (wood fiber) filter media.
By comparison, Fram Ultra has a full-synthetic (100% glass fiber) dual layer media with wire-backing, none of which the Mobil 1 oil filter has.
On top of all that, the 4548-12 standard performance tests show the Fram Ultra gets more tinier particles out than Mobil filters. (99% at 20 microns vs. 30 micron threshold).
Bottom line: Fram Ultra holds more potential garbage (grams) before it clogs than Mobil 1 oil filter, and the Ultra filters smaller junk out.
Not as good as Fram Ultra, but better than Mobil 1 Extended Performance oil filters:
--- Royal Purple oil filters
--- Amsoil EaO oil filters
--- MicroGreen oil filters
Mobil 1 Extended Performance oil filters are slightly better than Fram ToughGuard (TG) oil filters, BTW.... Fram's Ultra is the king though.
