Mobil Delvac Modern 15W-40 Super Defense V4 is a high-performance synthetic technology diesel engine oil engineered to provide reliable lubrication and protection for modern and older diesel engines operating under demanding conditions. Formulated using high-quality base oils and a balanced additive system, it delivers excellent control of oil thickening caused by soot build-up and high temperatures, while also providing strong resistance to oxidation, corrosion and deposit formation. This ensures dependable engine performance and long service life across a wide range of applications.
One of the key advantages of Mobil Delvac Modern 15W-40 Super Defense V4 is its excellent thermal and oxidation stability. The lubricant resists degradation at high temperatures, helping reduce sludge formation and high-temperature deposits. This contributes to cleaner engines, improved durability and extended service intervals in both on-highway and off-highway applications.
Mobil Delvac Modern 15W-40 Super Defense V4 also provides strong wear protection. The advanced additive system delivers effective protection against wear, helping extend the life of critical engine components such as pistons, rings and cylinder liners. It also offers protection against scuffing and corrosion, ensuring reliable engine operation under heavy loads and severe conditions.
Another important benefit of Mobil Delvac Modern 15W-40 Super Defense V4 is its excellent soot handling and viscosity control. The formulation helps manage soot-related oil thickening, maintaining viscosity and ensuring consistent lubrication performance. This supports efficient engine operation and helps extend oil life.
Mobil Delvac Modern 15W-40 Super Defense V4 also delivers effective detergency and dispersancy performance. The lubricant helps keep engines clean by preventing deposit build-up, supporting long-term reliability and reduced maintenance requirements. In addition, it provides strong Total Base Number (TBN) reserves, helping neutralise acids formed during combustion and protecting against corrosion.
Mobil Delvac Modern 15W-40 Super Defense V4 is recommended for use in naturally aspirated and turbocharged diesel engines from leading European, American and Japanese manufacturers. It is suitable for on-highway trucks as well as off-highway equipment used in construction, mining, quarrying and agriculture, and is ideal for mixed fleet operations. The product meets a wide range of specifications including API CF, CF-4, CG-4 and ACEA E7, along with approvals from manufacturers such as Volvo, Renault, Cummins and MAN.
Physical characteristics include a kinematic viscosity of approximately 110 mm²/s at 40°C and 14.6 mm²/s at 100°C, with a viscosity index of around 136. Mobil Delvac Modern 15W-40 Super Defense V4 has a density of approximately 0.869 kg/l at 15°C, a flash point of approximately 225°C and a pour point of approximately −36°C. The oil also provides a Total Base Number of approximately 9.2 mgKOH/g and a sulfated ash content of approximately 1.1%, supporting reliable engine protection and performance across a wide range of operating conditions.
