Bob is The Oil Guy is a WEALTH of info on this subject.
Carquest Blue Brand Filters (Wix) on my VX and any other vehicles I happen to procure, as the guys at BITOG have said time and time again Wix makes the best cheap filter, Purolator being the best at more $$ but much cheaper than an AMSOIL filter.
Another piece of the puzzle to consider is the Bypass valve which on some filters is complete junk and can cause the filter to bypass oil before it is even close to being clogged.
