Key Highlights
Mineral STOU · 10W-30 Viscosity · Engine, Transmission, Hydraulic & Wet Brake Use · High Detergency & Dispersancy · Rust & Corrosion Protection · Excellent EP & Anti-Wear Properties · All-Season Agricultural Performance
YEFE Styx STOU 10W-30 is a mineral Super Tractor Oil Universal (STOU) designed for use in the engine, transmission, wet brakes and hydraulic systems of tractors, harvesters, combines and other agricultural and off-road machinery with or without turbocharged engines. Its universal formulation simplifies maintenance by allowing one product to lubricate multiple systems, helping reduce the risk of misapplication and lowering inventory complexity for farmers, fleets and workshops.
The robust additive package provides strong detergency and dispersancy to keep engines and transmissions clean, while offering excellent protection against rust, corrosion, oxidation and wear under heavy-duty field conditions. The oil supports reliable cold starts and stable lubrication throughout the operating cycle, helping to maintain smooth operation of hydraulic components and oil-immersed wet brakes in all-season use.
YEFE Styx STOU 10W-30 is suitable for a wide range of OEM specifications for agricultural equipment and is available in multiple viscosity grades across the Styx STOU family, giving flexibility for different climates and machinery requirements. This product is not recommended for modern diesel engines equipped with Diesel Particulate Filters (DPF), where low-SAPS engine oils are required.
Packaging & Branding Support
YEFE offers affordable and adaptable customization solutions based on the package solutions and branding presentation that distributors and brand owners can introduce lubricant products easily and in a professional manner.
We plan to offer our customization services as a way of minimizing time-to-market with no compromise in the quality of the products and supply reliability.
