Over the last several months and with the advertsing on the SPEED channel our group has been talking about the additive Zmax.Has anyone used Zmax extensively in their bird and can they let us all know whether they actually see a difference in fuel mileage AND smoother running of the engine A couple of guys up here swear by it but I am unsure of the affect on these FE 352'S.
