A favorite filter here has been the Fram Ultra. It was similar in construction to the XP, but had/has fantastic filtering efficiency -- filtering out very fine particles. Recent construction changes have made it "less stout", but it will cetainly last your typical oil change interval cycle.
What changes has the Fram Ultra undergone recently?
