We have been using Prolong products for approximately two years. We have had excellent results in applying Prolong Hydraulic Treatment in preventative maintenance in gearboxes on HPM injection molding machines, Sargeant vacuum pumps, 1,000 gallon capacity hydraulic systems and countless other plantwide procedures. I rate Prolong products superior on all counts.
