It protects against corrosion, wear and helps clean the fuel system.


AirTec Cetane CS1 is a multi-purpose additive. It protects against corrosion, wear and helps clean the fuel system. Combustion is also optimized as active ingredients increase the fuel’s cetane value. CS 1 also protects against most diesel related problems and increases fuel mileage and service life at the same time!

For both older and modern engines, Cetane CS1 is compatible with SCR catalytic converters, particulate filters and high-pressure fuel injection systems (common-rail, pump-injection).
