Product Description
SINOPEC STOU Tractor Oil is a super tractor oil universal (STOU) formulated with high-quality mineral base oils and a multifunctional additive system to meet the requirements of a wide range of agricultural equipment manufacturers. This multifunctional oil can be used in many different agricultural applications and is particularly useful in equipment where there is a common lubrication system supplying oil for different applications. It is available in two SAE grades, 10W-30 and 15W-40.
Technical Features
· 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 compo- nents.
· Good antifoaming properties ensure optimum oil film thickness is maintained and re- duce oil leakage from the system.
· Good compatibility with most common seals and elastomer materials used in agricul- tural equipment prolongs seal life and reduces leakage.
· Available in two SAE Viscosity grades to suit the particular service conditions and am- bient temperatures.
· Excellent shear stability ensures good viscosity retention even in conditions of high temperature and heavy load, and prolongs the service life of hydraulic transmission systems.
Applications
· Suitable for 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.
