Engine Oil MOBIL 15W40 DELVAC MX SUPER DEFENSE V4 20L

Purpose and Specifications

Keep your diesel truck or heavy equipment running strong with Mobil Delvac MX Super Defense V4 15W-40, a premium 20-liter engine oil built for modern low-emission engines and older models alike. This high-performance oil handles extreme heat from turbochargers and intercoolers while flowing smoothly in cold starts down to -36°C pour point, protecting against wear during startup.

It excels in high-stress conditions, offering long oil life through superior thermal stability that fights sludge and deposits, keeping engines cleaner for thousands of kilometers. TBN reserves neutralize acids from combustion, preventing corrosion, while advanced soot handling maintains pumpability even after heavy use. Stay-in-grade shear stability ensures consistent protection up to operating temps over 225°C flash point.

• Ideal for on-highway trucks, construction gear, and mixed fleets from Mack, Volvo, Cummins, MAN, and more
• Meets tough specs like Volvo VDS-3, Mack EO-M PLUS, Cummins CES 20081, MB 228.3, ACEA E7, API CI-4
• 20L pail perfect for professional services, saving time on refills

When to Use / Replace?

Use this oil in naturally aspirated or turbocharged diesel engines running low or high sulfur fuel, especially in demanding fleets logging 100,000+ km yearly. Perfect for engines facing high soot loads from retarded timing or high-pressure injection.

Replace every 20,000-40,000 km or 12 months under normal heavy-duty use, or sooner at 15,000 km/6 months in severe conditions like dusty roads or constant idling. Check oil level monthly; change if it darkens excessively or loses viscosity. Shelf life is 5 years unopened in cool, dry storage.
