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.

True! I was mostly commenting on the guarantee part of it. I worked for Ashland and know for a fact that the 3000 mile oil change was nothing more than a marketing tool to get people into instant oil change places. I'm not sure but I don't think a single oem still reccomends lofs every 3000 miles. Even if they did,I'd still suspect it was at least partially a ploy to get people into their service bays for lofs!
