Common Rail Additive

Maintains and protects the entire fuel system from wear, deposits and corrosion. Improves engine running and prevents performance decrease. Increases the lubricity of diesel fuels. Clean engines need less fuel and reduce emissions.

Available pack sizes

250 ml Can sheet metal (Part No. 8372)

Technical Data Sheet


Diesel System Treatment is a combination of agents with a high proportion of lubrication improvers and cleaners. This product is therefore specially formulated to meet the demands of diesel engines with Common Rail and Pump-Injection high pressure injection using low sulphur diesel fuels and to give protection against wear. Other agents which have cleaning, dispersion and material protection properties maintain the operation of high-precision injectors. Due to the increased ignition performance, the fuel shows better combustion behaviour when the engine is cold and the pollution from odours in the exhaust is reduced

Intended use

For all diesel engines with and without diesel particulate filters – especially suitable for preventative use for common rail and pump-jet technology. Preventative. Tested for turbochargers. For adding directly to the fuel tank. Can contents are sufficient for up to 75 l fuel. Effect lasts up to 2,000 km.


  • optimizes engine performance
  • tested for catalytic converters
  • good corrosion protection
  • stable to oxidation prevents seizing and the injector needles from gumming up
  • excellent cleanliness
  • boosts the cetane number
  • guarantees low fuel consumption
  • minimizes wear – increases the lubricating effect
  • removes deposits from entire fuel system
  • guarantees optimum combustion

Areas of application

Added to diesel fuel for all diesel engines with Common Rail and Pump-Injection-Systems. Ideally suitable for preserving engines when decommissioned for long periods under extreme conditions.


  • The ignition performance is increased and the lubrication action and lubricity performance are improved only by adding the product to low-sulphur diesel fuels on a continual basis. One 250 ml can of the product is sufficient for 75 litres of fuel. Dosage 1:300
  • To keep the injectors clean and for corrosion protection, add Diesel System Treatment to the passenger vehicle diesel fuel tank every 2,000 km.
  • When decommissioning and preserving engines, add Diesel System Treatment to diesel fuel at the rate of 1 %. Follow the instructions on preservation.
  • Diesel System Treatment can be mixed with the fuel at any time since mixing takes place automatically.
