The Million Mile Van is the exception to this rule of course, but that van is the exception of a lot of rules... he hasnt changed his trans filter yet, according to ford that should have been done about 900,000 miles ago, he's let the same oil in his engine for 55,000 miles before changing it... If one of us tried that chances are, our engines would be cooked long before we hit that mark, it's a lot of hit or miss, and with that van ford hit it right on the bullseye!
