A one shot diesel additive designed to clean the diesel particulate filters (DPF) reducing the regeneration temperature required to allow the trapped soot particles to be burnt off. Ensures a cleaner more efficient DPF. Also designed to boost passive regeneration and cleaning of the catalytic converter, as well as the turbo compressor and its variable geometry vanes. Suitable for all types of diesel engines including the latest generation directly injected with CRD, TDI, JTD, HDI,EGR, Diesel Particle Filter and catalyser. This treatment requires no disassembling.
