Mobilfluid 428 – Universal Tractor Transmission & Hydraulic Oil (UTTO)

Advanced Multi-Functional Lubricant for Modern Agriculture and Off-Highway Equipment

Mobilfluid 428 is an extra-high-performance, multipurpose tractor oil designed to meet and often exceed the lubrication requirements of a wide range of equipment builders for hydraulic, transmission, clutch, PTO, and wet brake systems. Engineered to optimize performance under diverse and demanding conditions, it brings enhanced operational reliability to agricultural, construction, and quarrying machinery.

Key Features and Benefits

Universal Compatibility

Mobilfluid 428 serves as a true UTTO (Universal Tractor Transmission Oil), providing efficient lubrication across multiple systems—hydraulics, transmissions, wet brakes, and PTOs. This simplifies maintenance routines and reduces the risk of misapplication by covering a wide array of lubrication needs with a single product.

Enhanced Friction Control

Specially designed friction characteristics help reduce chatter in wet brakes and PTO drivetrains. This ensures quieter operation, improved operator comfort, and extended component life under harsh load conditions.

High Shear and Thermal Stability

Formulated with high-quality base oils and advanced additives, Mobilfluid 428 resists viscosity breakdown under extreme operating loads. It maintains viscosity under mechanical shear and offers outstanding resilience against thermal degradation, ensuring consistent performance and protection.

Superior Wear and Rust Protection

Integrated anti-wear and extreme-pressure additives reduce metal-to-metal contact and protect vital drivetrain components from premature wear. Corrosion inhibitors guard both ferrous and non-ferrous metals from rust and yellow-metal etching, enhancing longevity in humid or wet environments.

All-Temperature Performance

Mobilfluid 428 retains excellent flow and pumpability even in low temperatures, with a pour point near –48°C. Its high viscosity index ensures stable performance across a wide temperature range, offering reliable lubrication whether starting cold or operating in heat.

Clean Performance

This oil features strong thermal and oxidation stability, minimizing sludge and deposit formation. Good filterability supports clean hydraulic systems and reduced maintenance downtime.

Applications

Mobilfluid 428 is ideal for a wide array of off-highway machinery, including:

• Agricultural tractors and implements

• Construction equipment (loaders, graders, excavators)

• Quarry and earthmoving machinery

• Utility vehicles and municipal equipment

• Hybrid systems that combine hydraulics with mechanical drive systems

• Conventional CVTs featuring hydraulic pumps with planetary gear assemblies
