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
stocks and premium additives help reduce gear and bearing wear (see
photos), improve shifting and extend transmission life throughout drain
intervals of up to 500,000 miles/five years. Compared to conventional
fluids, Long-Life Synthetic Transmission Oil can help operators reduce
maintenance costs and increase productivity.
Year-Round
Performance
AMSOIL Long-Life Synthetic 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.
Resists Wear
AMSOIL Long-Life Synthetic 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 lubricating fluid film for increased wear resistance and longer
transmission life.
To prove its
effectiveness, AMSOIL installed SAE 50 Long-Life Synthetic Transmission
Oil in line-haul trucks and placed them into real-world service.
After 500,000 miles, a
transmission was disassembled and inspected by a calibrated ASTM rater.
Results reveal Long-Life Synthetic Transmission Oil provided outstanding
wear protection in all critical components. Examples include the input
shaft main drive gear and output shaft bearing, which both earned high
merit scores of 8 out of a possible 10 for wear. In addition, both
components showed no scuffing, spalling or corrosion, scoring perfect
10s in all areas.
Inhibits Foam
Churning gears introduce air into the fluid, causing foam. When bubbles
between gear surfaces collapse, metal-to-metal contact and increased
wear result. Long-Life Synthetic Transmission Oil contains foam
inhibitors to ensure formation of a strong lubricating film and
excellent wear protection.
Seal Friendly
Long-Life Synthetic Transmission Oil is compatible with seals to help
prevent leaks and extend seal life.
Applications
AMSOIL SAE 50 Long-Life Synthetic Transmission Oil is excellent for use
in manual transmissions requiring an SAE 50 lubricant found in
heavy-duty equipment. It is recommended for applications specifying any
of the following:
• Eaton PS-164 Rev. 7
• API GL-1 and MT-1
• Navistar/International TMS 6816
• Mack TO-A Plus
• Volvo I-Shift
• ZF Freedomline
• Meritor 0-81
Service Life
Follow the OEM drain interval for synthetic oil up to 500,000 miles or
five years, whichever comes first.
