YEFE Styx STOU SS 10W-40 provides:
- Synthetic, multi-grade STOU formulation based on highly refined mineral and synthetic base oils, suitable for engines, transmissions, hydraulic systems and oil-immersed wet brakes in tractors and agricultural equipment.
- High level of detergency and dispersancy to keep oil and systems clean, helping to remove and suspend impurities and prevent sludge and deposit formation.
- Excellent Extreme Pressure (EP) properties to protect heavily loaded gears and transmissions operating under high torque and severe field conditions.
- Excellent resistance against oxidation, helping maintain oil stability, viscosity and performance over the recommended drain interval.
- Very good protection against wear in engines, gear sets, hydraulic pumps and wet brakes, supporting long component life and reliable operation.
- Strong protection against corrosion and rust for internal components exposed to moisture, contaminants and variable operating environments.
- Effective control of foam-building, contributing to stable hydraulic performance and consistent lubrication film across systems.
- All-year usability with excellent cold-start behaviour, reduced friction and clean-running engines in agricultural machinery.
Typical specifications and performance levels:
- Engine applications: ACEA E3; API CG-4/CF-4/CE; API SF; MB 228.1.
