Mobilfluid 424
Mobilfluid 424 is an extra high-performance multipurpose tractor lubricant engineered to meet or exceed transmission and hydraulic fluid requirements for agricultural and off-highway equipment. The formulation combines high-quality base oils with an advanced additive package to deliver balanced performance in transmissions, hydraulic systems, drive axles and PTO units operating under severe conditions.
One of the key advantages of Mobilfluid 424 is its enhanced frictional properties. The fluid is specifically designed to optimise clutch and power take-off performance while reducing wet brake chatter. This helps provide smoother equipment operation, improved control and extended clutch life.
Mobilfluid 424 also provides strong anti-wear and extreme pressure protection. The formulation helps reduce wear in transmissions, hydraulic pumps and gears, extending component life and reducing maintenance costs. Excellent thermal and oxidation stability further helps minimise deposit formation and extend lubricant service life.
Another important benefit is its wide operating temperature capability. The high viscosity index and good low-temperature fluidity provide responsive hydraulic performance and effective lubrication in both cold and hot operating conditions. The fluid also offers excellent rust and corrosion protection, helping safeguard equipment in wet or humid environments.
Mobilfluid 424 is recommended for heavy-duty transmissions, differentials, final drives, hydraulic systems, wet brakes, PTOs and hydrostatic drives in agricultural, construction and quarrying equipment. It is suitable for applications requiring API GL-4 or SAE 80W lubricants (excluding hypoid gears) and may also be used where Type A, Dexron or Type F fluids are specified in commercial transmission applications.
Physical characteristics include kinematic viscosity of approximately 55 mm²/s at 40°C and 9.3 mm²/s at 100°C. Mobilfluid 424 has density of approximately 0.88 kg/L at 15.6°C, flash point of approximately 198°C and pour point of approximately −42°C. The fluid provides reliable multipurpose performance for modern tractor and off-highway equipment.
