A combination of agents which cleans, disperses, protects materials and boosts the cetane number. Developed for state-of-the-art operating fluids (lowsulfur diesel fuels with portions of biodiesel). The lubrication enhancer contained provides sufficient lubricity for diesel fuels 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 protects the entire fuel system from rust and corrosion. The outstanding cleaning effect keeps the components clean, prevents deposits and maintains the engine performance at a consistently high level.

With Cetane Plus for enhanced engine performance, less knocking, smoother running and easier starting. Cleans engine and injection systems and reduces seizing up and resinification of the injector needles. Guarantees optimal operation and energy-saving fuel-burning. Prevents corrosion and wear. Suitable for low-sulfur diesel fuels.


Suitable for all diesel engines with and without a diesel particulate filter. To be added directly into the fuel tank. Fully compatible with all conventional diesel and biodiesel fuels. 1 l is sufficient for 500 l of fuel (dosage 1:500). Mixing takes place automatically. Tested for compatibility with turbochargers.
