Purpose and Specifications

Mobil Delvac MX Extra 10W-40 is a premium heavy-duty engine oil with synthetic technology, perfect for diesel and gasoline engines in trucks, construction equipment, mining machines, and agricultural vehicles. This 20L drum delivers excellent wear protection to extend engine and component life, superior corrosion resistance to cut bearing wear, and advanced soot handling that prevents sludge buildup and filter clogging.

It flows smoothly at low temperatures down to -25°C for quick startups in cold weather, while staying thick and stable up to 150°C under heavy loads and turbo stress. Approved for major specs like Volvo VDS-3, Mack EO-N, Cummins CES-20078, Renault RLD-2, API CI-4, and ACEA E7, it suits European, Japanese, and American engines in severe on- and off-highway use.

When to Use / Replace?

Use this oil in high-output, low-emission engines with turbochargers or intercoolers facing extreme heat, dust, or long hauls. Ideal for mixed fleets including heavy-duty trucks and off-road machinery. Replace every 40,000-60,000 km or 12-18 months under normal conditions, or sooner at 25,000-40,000 km in severe dusty/hot environments to maintain peak protection. Shelf life is 5 years unopened in cool, dry storage.
