Full Synthetic 75W-85 Smooth Shift Manual Gearbox and Transaxle Oil (SYN75W85)

Nulon Full Synthetic 75W-85 Smooth Shift Manual Gearbox & Transaxle Oil (SYN75W85) is an extreme pressure API GL-4 fully synthetic gear oil, with superior high temperature stability when compared to conventional mineral gear oils. Ideal for use in transaxle applications with combined manual gearbox and differential.

Nulon SYN75W85 is formulated using hydrofinished base fluids with superior additive packages to enhance wear protection, corrosion protection, seal compatibility and low temperature characteristics. The optimized formulation has maximum oxidation and thermal stability to ensure fluid durability and performance during its life time.

The hydrofinished base oils used in SYN75W85 are Very High Viscosity Index (VHVI) base fluids that have advantages of low volatility for better oil consumption, low wax content for improved low temperature fluidity, high saturates level for excellent thermal and oxidation stability, and low sulphur and aromatic compounds for improved environmental outcomes.

Nulon SYN75W85 is designed mainly for manual transmission and transaxle application where API GL-4 is recommended. It is intended for use in axles with spiral bevel gears under moderate to severe speed and load conditions. It can also be used for axles with hypoid gears under moderate speeds and load conditions. Nulon SYN75W85 may be used in selected manual transmission and transaxle applications where API MT-1 lubricants are not suitable.
