During the cold season, various engine components are subjected to high levels of moisture, cold and other winter environmental influences. We will show you how to ensure that the engine system runs reliably even after the winter. Get your engine ready for spring.

Clean engine system, clean performance

Highly effective cleaning of the oil circuit

After the cold season, oil sludge, condensation and other deposits may have formed in the oil. If you are planning an oil change soon, you should take the opportunity to clean the inside of the engine at the same time: Motor Clean is the perfect solution for this.

Highly effective cleaning additives dissolve sludge and dirt. They are drained off with the used oil when the oil is changed. After an oil change prepared in this way, the fresh oil can develop its full performance in the engine: It runs with less wear.

Exhaust gas performance is optimized and inadequate lubrication is prevented. If you want additional protection for the engine, add one of our three oil additives against engine wear to the engine oil. Find out here which additive is suitable for whom.

  • prevents lubrication deficiency
  • tested for turbocharger
  • rapid and effective cleaning
  • gentle cleaning
  • reduces pollutant emissions
  • ideal with particulate filters and catalytic converters
  • does not attack common sealing materials
  • highly economical
  • simple to use

Smooth diesel engine running thanks to clean injection system

Recommended for the "internal" spring cleaning of the diesel engine: Diesel engine system cleaner. It removes deposits in the injection system and combustion chamber and prevents them from forming again. Clean engines consume less fuel and reduce pollutant emissions. 

The additive maintains all components of the injection system and prevents the nozzle needles from seizing and gumming up. It also increases the cetane number and thus improves the ignitability of the diesel fuel. Engine System Cleaner Diesel ensures smooth engine running and protects the entire fuel system against corrosion and wear. This leads to the original performance of the engine and low exhaust gas values.

  • prevents build-up of deposits
  • prevents seizing and injector gumming
  • protects injection system components from wear
  • guarantees optimum combustion
  • suitable for all diesel engines, including common rail and pumped-jet
  • removes deposits from entire fuel system

Smooth engine running for petrol engines

Vitamin boost for petrol engines: Engine System Cleaner Petrol removes deposits on injection valves, intake valves, spark plugs and in the combustion chamber and prevents them from forming again. It eliminates starting difficulties and rough engine running. In addition, the fuel additive maintains all components of the fuel injection system. Engine System Cleaner Petrol protects the entire fuel system from corrosion and improves throttle response and compression. It thus improves the exhaust gas values and the performance of the engine.

  • prevents corrosion in the fuel system
  • assures an optimum mixture
  • optimizes engine performance
  • ideal with catalytic converters
  • keeps injection nozzles clean
  • guarantees low fuel consumption
  • guarantees low pollutant emissions
  • removes deposits from entire fuel system

Like new on the outside

Optimum cleaning of the engine compartment


Whether it's dust, dirt or road salt: after winter, the engine compartment can look pretty battered and there is a risk of corrosion. The engine compartment cleaner makes engine compartments sparkling clean again. It dissolves oil and grease-based dirt, tar and brake abrasion. The engine compartment cleaner impresses with its high washing and cleaning effect and short application time. It is neutral towards plastics, rubber and paintwork and is free from chlorinated hydrocarbons (CFCs).

  • removes preservatives
  • high washing and cleaning efficiency
  • fast acting
  • releases dirt, oil and grease residues
  • does not attack plastics, rubber and paints

Perfect engine sealant for protection and shine

After using the engine compartment cleaner, you should preserve your engine so that it shines and gleams like new for a long time. The engine sealant is a high-gloss, water-repellent protective coating for preserving the engine compartment.

It prevents corrosion and is dirt-repellent. The engine, ignition cables and other units are protected from dirt and moisture thanks to a water-repellent and non-sticky protective film. The engine sealant dries quickly and is compatible with metal, rubber and plastic parts.

  • water repellent, non-sticky protective film
  • compatible with metal, rubber and plastic components
  • improves appearance
  • fast-drying
  • free of chlorinated hydrocarbons
  • excellent corrosion protection
  • wide operating temperature range
