Snake oil, any way you look at it. More reading from Amway/Amsoil propaganda. ALL HAIL THE PORCELAIN GOD OF AMSOIL/AMWAY!!!!!! Show some PROOF of these claims. I don't want to read what you regurgitate from some pamphlet. How many of these so-called Amsoil/Amway experts have a P.E. behind their names or have credentials from the ASME or API? I'm going to guess ZERO. Your day with the FTC will come.
