I emailed Auto-Rx....and they said that after the two applications are complete, to continue to use it by putting 3oz of Auto-Rx into your oil in every subsequent oil change. I don't remember reading anything about this in their website. Anyone know anything about this? Is this valid, or merely a ploy to sell more of their $25/bottle product?
