Im looking for the oil additive they call free?
Oil additives are junk and can actually ruin your engine. If they were so great, then the racing teams would use them. I have a degree in chemistry, and can tell you that Slick 50 (teflon) and all the rest are a waste of money. Keep your oil changed on a regular basis (3000-5000 miles depending on your driving) and your motor will run smoothly for a long time.
