Öl-Schlamm-Spülung Engine oil additive for internal engine cleaning before oil changes. Cleans black sludge from engine surfaces and binds it. During oil change, the sludge is removed from the system, reducing deposit formation in piston ring grooves, ensuring the permeability of the oil filter and oil supply holes. Prevents lubrication failure and protects the engine from damage. Suitable for all gasoline and diesel engines, with or without turbocharging and catalytic converters. Compatible with all types of engine oils. Application: 300 ml is enough for up to 5 l of oil. After adding, drive for approx. 100-300 km without engine overload. During this time, start the engine approx. 1-3 times. After 100-300 km, be sure to change the oil and filter. It is recommended to use the preparation every time before changing engine oil. Caution!
