You know, that's something that I've "YET" to try, heard about it, but haven't been brave enough . I don't think that I really want to , don't think it'll be maybe so good for seals. But at the amount that you're supposed to use , probably wouldn't hurt. Either way , I won't bother what I do works, I've been using one item since '97, have been though atleast 8, gave one to my brother-in-law who gained 5mpg on his Toyota p/up. Another gaget been using since '05, it broke in '09 bought another seen much better results, Much better, now I'm getting them installed on my other 2 vehicles. Plugs, bought them back in '08, when they came out, a couple of years ago the price came way down on them , I own 18 of those plugs, just sold one geo , so now I own 15 of those plugs.
