Mobil Delvac Legend 15W-40 Heavy Duty
Mobil Delvac Legend 15W-40 Heavy Duty is a high-performance multigrade synthetic blend diesel engine oil engineered to provide dependable protection for engines operating under severe service conditions. Designed for both on-highway and off-highway applications, it is suitable for use in a wide range of industries including trucking, construction, mining, quarrying and agriculture. The formulation combines quality base oils with an advanced additive system to deliver consistent performance across varying operating environments.
One of the key advantages of Mobil Delvac Legend 15W-40 Heavy Duty is its excellent thermal and oxidation stability. The lubricant resists breakdown at high operating temperatures, helping to control sludge build-up and deposit formation. This ensures cleaner engine operation and supports longer engine life, even in demanding heavy-duty applications.
Mobil Delvac Legend 15W-40 Heavy Duty also provides strong wear protection and shear stability. The formulation maintains its viscosity under high stress conditions, helping reduce oil consumption while protecting critical engine components such as pistons, rings and cylinder liners. This contributes to improved durability and reduced maintenance requirements.
Another important benefit of Mobil Delvac Legend 15W-40 Heavy Duty is its effective detergency and dispersancy performance. The advanced additive system helps keep engines clean by preventing the build-up of deposits and contaminants. This supports efficient engine operation and helps extend service intervals where appropriate.
Mobil Delvac Legend 15W-40 Heavy Duty also offers good corrosion protection and component compatibility. The lubricant helps protect internal engine surfaces from rust and corrosion while ensuring compatibility with seals and gaskets, contributing to longer component life and reduced risk of leaks.
Mobil Delvac Legend 15W-40 Heavy Duty is recommended for use in naturally aspirated and turbocharged diesel engines from European, Japanese and American manufacturers. It meets or exceeds a wide range of specifications including ACEA E3, API CF and MTU Oil Category 2, and is suitable for applications requiring API CF-4, CG-4, CH-4, Mack EO-M, Volvo VDS-2 and MAN M 3275-1, making it a versatile choice for mixed fleets.
Physical characteristics include a kinematic viscosity of approximately 116 mm²/s at 40°C and 15.2 mm²/s at 100°C, with a viscosity index of around 137. Mobil Delvac Legend 15W-40 Heavy Duty has a density of approximately 0.869 kg/l at 15°C, a flash point of approximately 233°C and a pour point of approximately −33°C. The oil also provides a Total Base Number of approximately 8 mgKOH/g and a sulfated ash content of approximately 1.1%, supporting reliable engine protection and performance across a wide range of operating conditions.
