Servo Gear HP oils are hypoid gear oils having long service life due to their extremely good oxidation stability. These oils meet API service classification GL-4, IS:1118-1992 ED Type GL-4, US Military MIL-L-2105 and UK Defence CS 3000A specifications. Servo Gear HP oils are recommended for hypoid, spiral bevel or worm gear transmission systems of cars, buses and trucks requiring EP type lubricants. Servo Gear HP 80W and 85W due to its very low pour point can be used for power transmission units of vehicles operating at sub-zero temperatures.
