Castrol CRB Turbomax 10W-40 is an advanced, heavy-duty diesel engine oil specially engineered with DuraShield™ Boosters to deliver up to double the engine life in demanding commercial transport and heavy equipment applications. Formulated to handle high thermal stress and soot loading, it protects modern diesel powerplants against severe wear, deposits, and oil degradation across long service intervals.

Featuring dual-action technology, Castrol's DuraShield™ formulation prevents soot agglomeration into large abrasive particles while creating a durable protective layer on critical moving surfaces. The bulk 208-litre drum provides a cost-effective, continuous fluid supply tailored for commercial transport depots, agricultural contractors, construction equipment fleets, and high-volume workshop service bays.

Key Performance Benefits

• DuraShield™ Booster Technology: Active technology prevents soot aggregation and forms a tough protective film to significantly extend engine component life.
• Abrasive Soot Control: Disperses fine soot particles to prevent valve train wear, liner polishing, and oil thickening during high-load operations.
• Thermal & Oxidation Defense: Fights high-temperature oxidation and varnish accumulation, maintaining fluid integrity and system cleanliness.
• Rapid Low-Temperature Flow: 10W-40 synthetic-blend flow characteristics ensure swift oil pressure buildup on start-up, reducing wear during cold ignition.
• Extensive Commercial Fleet Coverage: Formulated to meet rigorous OEM requirements, including Mercedes-Benz, Volvo, MAN, Renault, and Cummins heavy-duty engine standards.
• High-Volume Workshop Economy: 208-litre barrel offers maximum cost efficiency and uninterrupted supply for commercial fleet operations and main dealer workshops.
