Autoschlüssel  Engine Flush is suitable for use in all diesel and gasoline engines, with and without turbochargers. The combination of active ingredients reliably dissolves operational contaminants and resin deposits throughout the entire oil circuit. Aggressive residues from the combustion process are eliminated. The dissolved contaminants are removed from the engine with the used oil during an oil change. The product contains highly effective lubricant additives that reliably protect the engine during the cleaning process.

 Advantages: Only a clean engine develops its full power! Easy application with no additional effort. Deposits and residues on piston rings, oil channels, and housing walls, as well as on hydraulic tappets and the valve train, are permanently removed. The result is significantly improved and more even compression in all cylinders. Fuel and oil consumption, as well as wear, are reduced. Reduced exhaust emissions contribute to environmental protection and increase the service life of the catalytic converter. Contamination of the fresh engine oil by residues and deposits from the used oil is reduced.
