This DIESEL Service KIT is a great solution and maintenance between oil changes. It includes 5 products as shown:

  • Start by adding engine clean to engine oil, let engine idle for 10-15 min. than change oil and oil filter. After adding new oil + new oil filter add Nano Engine Protect.  
  • Next add (in tank) Diesel  Common-Rail Diesel System Clean + Protect 
  • AFTER approx. 3-4000 miles add Diesel System Clean,
  • AFTER approx. 3-4000 miles add Diesel DPF Clean
  • Repead when next oil change is due
  • Please read instructions on the label and below. DO NOT MIX products



Product properties:

• removes all sludge, dirt and contamination from internal engine surfaces

• boosts power and reduces oil and fuel consumption by removing harmful varnish deposits from the piston ring and upper cylinder area

• cleans and quietens hydraulic valve lifters

• neutralizes engine acids

• extended life span of the engine

  • Area of application: For all petrol and diesel engines, gearboxes and differentials.
  • Consumption: Add to old oil, run engine at idle for 10-15 minutes. Drain as normal, fit new filter and fill up with new oil.
  • Application Consumption: 250 ml for 5 ltr. oil
  • Reaction time: Approx. 15 minutes

Recomendation: after oil change add 43218 AUTOPROFI Nano Engine Protect 250ml




  • Product properties: Nano Engine Protect creates a highly active nano barrier in the oil which protects all the internal surfaces of engines and equipment such as oil system, manual gearboxes and differentials. Seals, o-rings and shaft seals are kept supple. Improved oil flow during cold start, smoother and quieter engine running, improved performance, extended life of equipment, and excellent “run dry” emergency properties
  • Area of application: Service product for use in the oil system of 4-stroke petrol and diesel engines. Applicable for common rail as well as pump injector fuel systems and recommended for engines with turbo charger, catalytic converter and DPF filters. Compatible with all engine oils.
  • Application: Add to oil system after each oil change. We recommend cleaning the oil system with AUTOPROFI Engine Clean (43210) before use. Observe the maximum oil quantity! In power-steering systems, manual transmissions and differentials use at ratio 1:10.
  • Note: When using in vehicles with wet clutch, observe the manufacturer's instructions!
  • Application Consumption: 250 ml sufficient for 5 liters of oil. Mixing ratio: 1:20
  • Reaction time: while engine is running

• prevents wax formation and isolates moisture in the fuel 

• lubricates all moving parts of the diesel system

Area of application: For all diesel engines, particularly recommended for direct fuel injection and common-rail systems

Application: Add to the fuel tank. Add every 6 months to the diesel system before filling up with diesel. 

Application Consumption: 250 ml for up to 60 ltr. diesel. 

Reaction time Works: during operation.


DPF Clean

High Power Cleaner for Diesel Particle Filters

Product properties:

• permanent and complete filter cleaning while driving

• no assembling, no disassembling, no standing times, no troubles

• reduces ignition temperature of the soot collected in the diesel particle filter

• no formation of secondary emissions

Product properties: Suitable for all diesel engines with particle filter, can be mixed with all diesel fuels.

Area of application: Add to the diesel fuel tank before filling up. Regular use every 3 months is recommended.

Application Consumption: 250 ml for 60 ltr. diesel

Reaction time: Works during operation


Vehicle chemical products as a solution suited to the current market value

 Regenerating the diesel particulate filter: avoid clogging and total failure

 If you only use your diesel on short journeys, you risk damaging the diesel particulate filter, which could lead to poor performance and costly repairs. Only preventive measures or a thorough cleaning can prevent the accumulation of ash and soot. Vehicle chemical products offer a good solution for the purpose that suits to the current market value.

 Every day city traffic. Always just from one red traffic light to the next one. Many diesel drivers know this scenario and probably its consequences: eventually it will be there, the yellow light, indicating that the diesel particulate filter (DPF) is full. Occasionally, a few hundred miles are sufficient on short urban journeys, so that the soot particle filter is clogged. Because during the short drive time, the engine does not reach the optimum operating temperature that is needed for the filter to regenerate. The consequences are clearly noticeable: The car accelerates worse, the fuel consumption increases and the engine runs more frequently in the emergency program. In the long term, serious damage and costly repairs may occur. At the same time, the clogging of the diesel particulate filter can be prevented for a car lifelong.

 Avoid soot accumulations, the processes that take place in a diesel particulate filter: In every DPF, there are two substances that accumulate over time. One is soot, the other ashes. To remove the soot, every diesel vehicle – depending on the model and manufacturer – initiates a filter regeneration every few hundred kilometers. However, 500-550 °C (932-1022 °F) are needed in the exhaust gas flow and these temperatures are not reached on short distances. Thus, it does not come to self-cleaning. "So that the failure of the particulate filter can still be avoided. The recommended vehicle chemical solutions: With the help of certain formulations, it is possible to reduce the ignition temperature of the collected soot, so that it is burned on short distances. Anyone who regularly adds such products to the diesel fuel can prevent the DPF from clogging in short-distance operation.

 Remove ash accumulations

 While soot problems are easily avoided, ash accumulations are much more difficult to remove. This substance, which accumulates in the DPF over time, can only be removed by dismantling the particulate filter. The filter must be thoroughly rinsed so that the ash is eliminated in all corners. Here, too, there are vehicle chemical solutions that work thoroughly, but still gently." In addition, these applications are significantly cheaper and suit to the current market value than changing the soot particle filter. The installation of a new DPF is very expensive, the vehicle chemical cleaning is much more reasonably priced.
