DNG (Diesel and Natural Gas Engine) Top Off, enhanced by billions of spherical Tungsten Disulphide Nanoparticles. These Energy Reducing, Anti-Wear, Anti-Friction and Extreme Pressure particles serve as submicron-sized shock absorbers, preventing exposure to hydraulic/shear pressures, and also function as tiny ball-bearings that roll on impact, exfoliate and attached to surfaces, improving anti-friction and anti-wear properties of host oil.
