Specifically Engineered for 500,000-Mile Service Life in Over-The-Road Trucks
AMSOIL SAE 50 Long-Life Synthetic Transmission Oil is specially formulated to meet the demanding requirements of manual transmissions found in high-torque, heavy-duty line-haul trucks and other commercial applications. Its synthetic base oils and premium additives help reduce wear (see images), improve shifting and extend transmission life throughout drain intervals of up to 500,000 miles/year. Compared to conventional fluids, Long-Life Transmission Oil can help operators reduce maintenance costs and increase productivity.
AMSOIL Long-Life Transmission Oil’s synthetic base oils withstand the pressures of high-load, high-torque applications. As a result, it resists viscosity loss due to mechanical shear to provide a durable lubrication fluid film for increased wear. resistance and long transmission life.
To prove its effectiveness, AMSOIL installed SAE 50 Long-Life Transmission Oil in line-haul trucks and placed them into real-world service. After more than 500,000 miles, a transmission was disassembled and inspected by a calibrated ASTM rater. Results reveal Long-Life Transmission Oil provided outstanding wear protection in all critical components (see images).
AMSOIL Long-Life Transmission Oil’s high viscosity index translates into better high- and low-temperature performance compared to conventional fluids. In cold weather, it provides easier shifts and reduced fluid drag for increased fuel economy. Its exceptional thermal stability inhibits chemical breakdown and sludge formation at high operating temperatures to help transmissions run cleaner.
SAE 50 Long-Life Synthetic Transmission Oil
Specially formulated to meet the demanding requirements of manual transmissions found in high-torque, heavy-duty line-haul trucks and other commercial applications. Its synthetic base stocks and premium additives help reduce gear and bearing wear, improve shifting and extend transmission life throughout drain intervals of up to 500,000 miles/five years.
Churning gear introduce air into the fluid, causing foam. When bubbles between gear surfaces collapse, metal-to-metal contact and increased wear can result. Long-Life Synthetic Transmission Oil contains foam inhibitors to ensure formation of a strong lubricating film and excellent wear protection.
