Diesel, Super petrol, E10, B7: The choice at the petrol station is increasingly complex. Internationally varying legislations, highly developed motor technology and increasingly stricter emission standards are the reasons for a reduced harmony between engine and fuel.

The chemical processes in fuel systems generate contamination, deposits, coking and varnish.


New technological cleaning concepts aim less at a Formula 1 feeling but rather at preservation of the fuel system. This includes e.g. keeping the fuel injection nozzle holes, which nowadays have the same diameter as a human hair, free of coking and deposits.

TUNAP fuel and manifold system cleaning products help get you back on the road quickly at economic costs for chemicals and tools and have great potential to generate external economies.
