A new “beyond GL-5” gear lubricant technology has been developed which combines soluble additives with a dispersed borate solid lubricant. The L-37 and L-42 axle tests as well as laboratory bench tests show a strong synergistic effect between the solid lubricant and the soluble additives. The new technology shows improvements over conventional chemistry in antiwear performance, seal compatibility, and oxidative/ thermal stability. These improvements were demonstrated in over 17 million field test miles in axles and transmissions of Class 8 trucks.
