Mobil Delvac 1 Gear Oil 75W-90
Mobil Delvac 1 Gear Oil 75W-90 is a fully synthetic drivetrain lubricant engineered to meet the rigorous performance requirements of modern heavy-duty equipment. Designed for use in axles, final drives and non-synchronised manual transmissions requiring API GL-5 and MT-1 performance, this advanced lubricant combines high-quality synthetic base oils with a state-of-the-art additive system. It delivers exceptional protection and performance in applications subjected to extreme pressure, heavy loads and wide temperature variations.
One of the key advantages of Mobil Delvac 1 Gear Oil 75W-90 is its outstanding thermal and oxidation stability. The lubricant resists breakdown at elevated temperatures, helping prevent deposit formation and maintain clean gear components. This contributes to longer lubricant life and supports extended drain intervals, making it ideal for modern fleets operating under demanding conditions.
Mobil Delvac 1 Gear Oil 75W-90 also provides exceptional wear protection. The advanced additive system offers strong extreme pressure performance, helping protect gears and bearings from wear under both low-speed/high-torque and high-speed conditions. This reduces the risk of scuffing and scoring, extending the life of drivetrain components and improving reliability.
Another important benefit of Mobil Delvac 1 Gear Oil 75W-90 is its excellent shear stability. The lubricant maintains its viscosity and film strength even under severe operating conditions, ensuring consistent lubrication performance throughout its service life. This stability helps maintain effective protection across extended service intervals and demanding duty cycles.
Mobil Delvac 1 Gear Oil 75W-90 also delivers excellent low-temperature fluidity. The synthetic formulation ensures easy start-up and rapid lubrication of components in cold conditions, reducing wear during start-up. At the same time, it provides strong oil film thickness at high temperatures, ensuring reliable protection across a wide operating range. The formulation also offers friction reduction benefits, which may contribute to improved fuel economy and reduced operating costs.
Mobil Delvac 1 Gear Oil 75W-90 is recommended for use in heavy-duty manual transmissions, axles, differentials and final drives in both on-highway and off-highway equipment, including trucks, buses and machinery used in construction, mining and agriculture. It meets or exceeds a wide range of industry and OEM specifications including API GL-5, API MT-1, SAE J2360, MB 235.9 and various approvals from ZF, MAN, Volvo and Dana, making it suitable for a broad range of applications.
Physical characteristics include a kinematic viscosity of approximately 120 mm²/s at 40°C and 15.0 mm²/s at 100°C, with a viscosity index of around 140. Mobil Delvac 1 Gear Oil 75W-90 has a density of approximately 0.86 kg/l at 15.6°C, a flash point of approximately 205°C and a pour point of approximately −48°C, supporting reliable lubrication performance across a wide range of operating conditions.
