z-max,anyone ever try it??

I am not a fan of oil additives, most are total crap(like slick 50) but Z-Max is different than all other additives. Z max is the automotive version of an additive AVblend that is used in aircraft. It is the only additive that is FAA approved. It has been throughly tested and has shown to reduce wear, prevent rust and reduce dry start damage. I haven't used Z max but I have used AVblend in my cars and it dose work.
