Purpose and Specifications

Mobil Delvac Modern 10W-40 Super Defense V1 4L is a premium heavy-duty diesel engine oil designed for modern trucks, buses, and off-road equipment. It delivers outstanding protection against wear, sludge, and high-temperature deposits, helping your engine last longer with fewer repairs. This 10W-40 oil flows easily at cold starts down to -42°C for quick protection, while staying thick and stable up to extreme operating temps over 100°C in heavy loads.

Meets top specs like MACK EO-M Plus, Volvo VDS-3, MAN M 3277, and API CF for reliable performance in Euro IV/V/VI engines and older models. The advanced formula handles soot and acids to support extended drain intervals up to 100,000 km or 12 months under normal fleet use, cutting downtime and costs.

• Long engine life: Cuts wear on bearings, pistons, and rings
• Cold weather ready: Pumps fast at low temps for safe startups
• Hot duty tough: Resists breakdown in turbocharged, high-output diesels
• Clean running: Reduces sludge and deposits for smoother operation

When to Use / Replace?

Use in severe on/off-highway diesel applications like construction, mining, or long-haul trucking where engines face high heat, soot, and loads. Ideal for vehicles needing Volvo VDS-3 or Mack EO-N approval. Replace every 60,000-100,000 km or 12 months based on oil analysis, or sooner in dusty/extreme conditions. Shelf life is 5 years unopened in cool, dry storage.
