Abstract:

The U.S. Army Tank Automotive Research and Development Engineering Center TARDEC desires to improve the fuel efficiency of the U.S. Army Tactical Wheeled Vehicle TWV fleet. This report covers efforts to quantify potential fuel efficiency changes in Light Tactical-Wheeled Vehicles LTV and Heavy Tactical-Wheeled Vehicles HTV with the use of improved differentialaxle lubricants. Candidate lubricants were synthetic based 75W-90 and 75W-140 products, and were compared to a baseline petroleum based 80W-90 gear oil. Fuel consumption improvements were noted for both candidate oils for the LTV, while the HTV showed general trends of improvement for the lower viscosity 75W-90 candidate, and detriment when using the heavier 75W-140 candidate. Stationary axle efficiency testing is recommended to further explore this relationship.
