Bridgestone Firestone Retail actually uses this oil for an option at their stores in the Seattle, Washington area. I read about it in one of our companies newsletters (I work for BFRC), and as the article was explaining, the oil is just as good a new oil. It has all been re-refined, and the correct additives added to it. Not saying I'll use it, but it is starting to become an option at some oil change places.
I've already been using recycled oil in my XJ. Until yesterday, I was having a major oil leak and continued filling my jeep with oil from old people's cars (since they are not driven near enough to use up the oil. Figured since they were no longer going to, I may as well put it to work).
