A combination of agents which cleans, disperses, protects materials and boosts the cetane number. Developed for the latest operating fluids (low-sulfur diesel fuels with portions of biodiesel). The lubricity improver contained provides better lubricity for diesel low in sulfur. The increase in ignition performance improves the combustion of the fuel, whereby the exhaust emissions are reduced. The high proportion of corrosion protection additives reliably protects the entire fuel system from rust and corrosion. The outstanding cleaning properties prevent deposits, keep the components clean and the engine performance at a consistently high level.

With Cetane Plus for more engine power, less knocking, quieter run, easy starting. Cleans engine and injection system and prevents jet needles from fusing and gumming.
