Mobil Delvac Modern 15W-40 Super Defense (MX) – 20 Litre

Premium Heavy-Duty Diesel Engine Oil for Extended Engine Life & Fleet Efficiency

Product Overview

Mobil Delvac Modern 15W-40 Super Defense (MX) is a high-performance, mineral-based diesel engine oil specifically designed to meet the demanding lubrication requirements of modern turbocharged and naturally aspirated diesel engines operating in both on-road and off-road environments.

Engineered with high-quality base stocks and a proven additive system, this oil provides excellent protection against wear, deposits, corrosion, oil thickening, and high-temperature oxidation. It is particularly suited to fleets, logistics operators, agricultural users, and industrial diesel equipment owners who prioritize long engine life, superior cleanliness, and maximum uptime.

This 15W-40 multigrade engine oil delivers reliable all-season protection, including cold-start fluidity and high-load, high-temperature durability, even in harsh operating conditions typical of Australian environments.

Packaged in a 20-litre container, Mobil Delvac MX 15W-40 is ideal for users seeking value and high performance in medium- to large-scale diesel engine maintenance.

Key Benefits

✅ Proven Wear Protection

Mobil Delvac MX is fortified with anti-wear additives that form a durable lubricating film on metal surfaces. This ensures engine components like cylinder liners, pistons, valves, camshafts, and bearings are shielded from abrasive wear and metal-to-metal contact—extending engine life even under severe load conditions.

✅ Thermal and Oxidation Stability

The oil’s high oxidative stability resists thermal breakdown and sludge formation, particularly in high-temperature and stop-start urban environments. This maintains optimal engine cleanliness and promotes efficient operation throughout the oil’s service life.

✅ Soot Handling and Deposit Control

In EGR and older non-EGR engines, soot accumulation can reduce oil performance. Mobil Delvac MX’s dispersant technology helps to trap and suspend soot, preventing clogging and deposits, and ensuring smooth engine operation with minimal sludge.

✅ Extended Drain Intervals

When used in accordance with OEM guidelines and under suitable conditions, Mobil Delvac MX supports longer drain intervals than conventional diesel oils—helping reduce maintenance downtime and operating costs.

✅ Multigrade Performance for All Seasons

The 15W-40 viscosity grade provides:

• Good cold-start flow and protection during winter.

• High-temperature lubrication stability during summer or heavy-duty operations.

This makes it a versatile choice for fleets operating in varying climates and terrains.
