my truck never does short run stuff. it is hooked to a trailer hauling ass. and i have never seen an analysis that said the oil was bad on a decent engine in 10k. but i am just following what the truck wants me to do. hell i do 10k changes on my 03 escalade. it has 240 or so on it, hell it is still on the stock plugs. but again, no short trip stuff to speak of.
