LA Syn-Gear M 75W-90

Product description

LA SYN-GEAR M 75W-90 is a full synthetic base oil coupled with a robust additive system and an improved viscosity modifier to provide a high viscosity index, low pour-point, fully synthetic gear oil providing reduced friction, fuel savings, better low temperature start-up protection and longer life than most conventional gear oils.

LA SYN-GEAR M 75W-90 is a proven heavy duty automotive multi-purpose, sophisticated extreme pressure gear lubricant and meets the requirements of the API Service Classification GL-5 and Military Specification MIL-PRF-2105E.

LA SYN-GEAR M 75W-90 is fully inhibited against foaming, oxidation and corrosion, and contains sulphur/phosphorous extreme pressure additives which ensure that the oil meets all the requirements of modern automotive differentials, manual transmissions and final drives to operate at high load-carrying capacity at sustained high speed under high torque loading conditions, where such gear oils are required.

Applications and Benefits

LA SYN-GEAR M 75W-90 can be used in manual transmissions and differentials using hypoid and spiral bevel gears which specify this grade of gear oil.

LA SYN-GEAR M 75W-90 meets or exceeds the requirements of:

  • API GL-5, MT-1
  • MIL-L-2105D
  • MIL-PRF-2105E
  • GM HN-1561, HN-2040
