Mobil Delvac Modern 10W-40 Super Defense V1
Mobil Delvac Modern 10W-40 Super Defense V1 is a semi-synthetic, extra high-performance diesel engine oil engineered to provide reliable lubrication and protection for modern high-output diesel engines operating under severe conditions. Formulated using high-quality base oils and an advanced additive system, it delivers excellent low-temperature fluidity, strong high-temperature viscosity retention and effective control of oil volatility. The formulation is designed to support extended oil drain intervals while maintaining engine performance and durability.
One of the key advantages of Mobil Delvac Modern 10W-40 Super Defense V1 is its excellent resistance to oil thickening, degradation and deposit formation. The lubricant is engineered to control sludge build-up and high-temperature deposits, helping maintain engine cleanliness and ensuring efficient operation over extended service periods. This contributes to improved reliability and reduced maintenance costs.
Mobil Delvac Modern 10W-40 Super Defense V1 also provides outstanding wear protection. The advanced additive system delivers strong protection against scuffing, bore polishing and ring sticking, helping extend the life of critical engine components such as pistons, rings and cylinder liners. This ensures reliable engine performance even under heavy-duty operating conditions.
Another important benefit of Mobil Delvac Modern 10W-40 Super Defense V1 is its extended Total Base Number (TBN) reserve. This helps neutralise acids formed during combustion, providing effective corrosion protection and supporting long-term durability. The lubricant also offers strong shear stability and low volatility, helping maintain viscosity and reduce oil consumption under high temperature and heavy load conditions.
Mobil Delvac Modern 10W-40 Super Defense V1 also demonstrates excellent low-temperature performance. The oil flows quickly during cold starts, ensuring rapid lubrication and reducing wear on engine components during initial operation. This supports reliable performance across a wide range of climates and operating environments.
Mobil Delvac Modern 10W-40 Super Defense V1 is recommended for use in naturally aspirated and turbocharged diesel engines from European and Japanese manufacturers. It is suitable for on-highway trucks and off-highway equipment used in construction, mining, quarrying and agriculture. The product meets or exceeds a wide range of specifications including API CF, CH-4, CI-4 and ACEA E4/E7, along with approvals from manufacturers such as MAN, Volvo, Renault and MTU.
Physical characteristics include a kinematic viscosity of approximately 98 mm²/s at 40°C and 14.6 mm²/s at 100°C, with a viscosity index of around 154. Mobil Delvac Modern 10W-40 Super Defense V1 has a density of approximately 0.868 kg/l at 15.6°C, a flash point of approximately 244°C and a pour point of approximately −42°C. The oil also provides a Total Base Number of approximately 15.3 mgKOH/g and a sulfated ash content of approximately 1.6%, supporting reliable engine protection and performance across a wide range of operating conditions.
