  • Diesel engines, transmission and hydraulic systems, wet brakes and final drives of tractors and other agricultural or forestry equipment with common lubrication systems, where a STOU type lubricant is required.



This multifunctional oil, suitable for many agricultural and forestry applications, avoids the problems of accidental
misapplication, which could cause equipment failure, and also saves on oil inventory costs.

Low pour point and high viscosity index ensure excellent low-temperature fluidity and good start-up and hydraulic
performance, even under cold conditions, preventing start-up wear and ensuring smooth hydraulic operation.

A special friction modifier ensures smooth action in wet brakes and power take-off clutches, minimising vibration,
chatter, stick–slip and squawk, and prolongs service life.

Good antiwear performance protects moving parts from wear and metal fatigue, extending equipment life; excellent
protection against gear scuffing, pitting and wear in applications where an API GL-4 product is required.

Excellent thermal and oxidation stability minimise the formation of deposits that could lead to component wear, and
also ensure longer oil life.

Excellent protection against rusting and corrosion, extends the life of system components.
Good antifoaming properties ensure optimum oil film thickness is maintained and reduce oil leakage from the system.

Good compatibility with most common seals and elastomer materials used in agricultural equipment prolongs seal life and reduces leakage.

Available in two SAE viscosity grades to suit the particular service conditions and ambient temperatures.
