Plant operating a leased fleet of 42 “5-year throwaway” lift trucks, was experiencing so many gearbox failures, downtime and repair-related issues, that they decided in the third year of operation to install 10% Prolong AFMT into each truck.  Their desire was to “get through” two more years before having to discard these trucks for a new leased fleet.  The fleet is now in its ninth year of operation and running so well that, in the eighth year, the entire fleet was purchased.
