Gear Oil 140 is a premium, heavy duty, mineral automotive gear oil manufactured with modern extreme pressure additives and friction modifiers meeting the requirements of API GL-5/6 and MT-1 as well as many other manufacturer specifications. It contains the correct dosage of limslip additive eliminating the need for a additional product when used in limited slip differentials. Product is coloured "Blue".
Gear Oil 140 is designed for use in differentials, both hypoid and limited slip, in passenger cars, light commercials, 4WDs, trucks, construction, earth moving and agricultural equipment where such a viscosity grade is required. Many Nissan 4WDs are recommended to use an SAE 140 oil in the rear differentials (check Penrite Recommendation Guide).
Gear Oil 140 is particularly recommended in higher ambient conditions, or for quietening noisy differentials where the noise is due to wear, thus prolonging the life of the unit before rebuild is required.
Gear Oil 140 provides a superior level of protection in heavy duty applications, where shock load conditions can be extreme. The multi-purpose formulation allows greater flexibility while minimising inventory levels, especially for differential applications.
For competition, consistent high temperature or extreme high load operation, fully synthetic Pro Gear 80W-140 should be used.
