Granted the damn thing holds 6.9 quarts, but that's still amazing. Kind of debunks the 3k mile oil change myth, huh? There are numerous tests on taxi fleets, etc. that say there is no advantage to changing oil at 3k miles as opposed to say 7.5k.

My father-in-law runs Amsoil 20,000 miles between changes...he also sends it out to get tested and every time it's come back they say it's good for more miles.
