Great find on that article, I'm going to post that on the CLC forum.
I remember when that whole "3000 miles or every three months" thing was cooked up as oil change shacks started popping up all over the U.S.. I think that was a marketing ploy for them, sad what it has done for the environment. I follow my vehicle's manual, typically 7,500 mile intervals. With all the vehicles I have around here, I'd kill myself trying to keep up with all of them at 3,000 mile oil changes.
