How many actual users do you know? I mean really know as in face to face conversations? It is very easy to be a dozen people on the WWW, and hype a product to the naïve less educated. Remember a fool and his money? To trick the software on these sites use a different computer from a different location. Best I can tell maybe there's about 3 people using Synlube, using many different handles, all with an agenda. I don't know any of them, and from what I can tell I'd rather not.
Now as far as Amsoil. RL, Pennzoil, Castrol, etc. I think most of the testimony is valid, although sales people with agendas tend to embellish. Still the products have a real following, and I'd use any one of them before I try Synlube. Hey but each his own!!!!!!!!!!!
Things like non existant addresses are three strikes in my book, and there are several other strikes if you read thru these threads again.
