Purpose and Specifications

It delivers top protection in modern low-emission engines with DPF filters and EGR systems, while working perfectly in older engines too.

This oil flows smoothly at cold starts down to -25°C to cut wear, stays thick up to 150°C for high-heat hauling, and handles soot buildup to keep your engine efficient. It cuts oil top-ups, fights rust and sludge, and supports drain intervals up to 100,000 km or 12 months in severe use, following your truck maker's guidelines.
