United Hydro 400 is formulated using a robust additive package and hydro-treated base oil to deliver real performance in today’s heavy-duty diesel engines, especially those fitted with modern features like Super-charger, Turbo-charger and multi-valves drive trains.

United Hydro 400 is a proven choice in the transportation industry in the Asian region. It minimizes high-temperature carbon deposits, which is by far the most concerning issue for today’s heavily loaded modern diesel engines. The reduced carbon build-up means fewer rings wear and cylinder bore polishing resulting in much-reduced diesel consumption, less ring breakage and piston skirt scuffing. Its high ability to neutralize acidic by-products from diesel combustion ensures minimum corrosion of the engine parts throughout the lengthy oil drain interval.
