Description
Mobil Delvac Modern™ 20W-50 Super Defense is a premium high-performance diesel engine oil engineered to deliver excellent lubrication and reliable protection for today’s diesel engines. It helps extend engine life and maintain performance across a wide range of operating conditions. ExxonMobil recommends this lubricant for use in various industries, applications, and mixed fleets.
This advanced diesel engine oil provides exceptional performance in both modern low-emission diesel engines and older engines operating on low- or high-sulphur fuels. Formulated with high-quality base oils and an advanced additive package, Mobil Delvac Modern 20W-50 Super Defense offers superior control of oil thickening caused by soot accumulation and elevated operating temperatures. It also delivers excellent resistance to oxidation, corrosion, and high-temperature deposit formation.
Mobil Delvac Modern™ 20W-50 Super Defense is fully compatible with Mobil Delvac MX 20W-50 and can be used as a direct replacement without compromising performance or protection.
Features and Benefits:
1.Superior Thermal and Oxidation Stability: The formulation resists thermal breakdown and oxidation, helping reduce sludge formation, deposits, and excessive viscosity increase. This supports cleaner engine operation and longer lubricant life.
2. Strong TBN Reserve for Enhanced Protection: A robust Total Base Number (TBN) reserve helps neutralize harmful acids formed during combustion while effectively controlling deposits, contributing to improved engine durability.
3. Excellent Shear Stability: The oil maintains its viscosity under severe operating conditions, ensuring reliable wear protection and consistent lubrication performance throughout the service interval.
4. Advanced Detergency and Dispersancy: Powerful detergent and dispersant additives keep engine components clean by preventing sludge and deposit formation, helping extend component life and reduce maintenance requirements.
5. Improved Soot Handling Capability: Enhanced soot control helps maintain proper oil viscosity and improves used-oil pumpability, even in engines operating under demanding conditions.
6. Reliable Low-Temperature Performance: Good low-temperature properties support easier engine start-up and help reduce wear during cold starts.
7. Seal and Gasket Compatibility: The formulation is compatible with engine seals and gaskets, helping prevent leaks and supporting longer service life of engine components.
