Just reading the newest Popular Mechanics magazine, and see a 2 page ad, Mind you, this is an ad, not an article, for an additive called revitalizant EX120. They make several different things, and all of them claim to treat the metal and do all sorts of miraculous things to extend the life of the engine etc. Has anybody even heard of it, or better yet, had any experience with it. My thought is it is just another expensive snake oil. I am not a big fan of any additives, but if something new would happen to come along that would slow the oil consumption in my old 1980 GMC with 160000 miles, I would give it a try. Supposedly it lasts 60000 miles You can find the company at [XADO sales link removed]
