Tunap 157 Interior Engine Cleaner

The Tunap Premium interior engine cleaner (400ml) is a solvent-free engine cleaner. This ensures full dispersion and removal of dirt deposits in the engine oil system. This flush contains an additive for lubrication of components during cleaning to get more out of your engine. This reliably removes oil sludge deposits (black sludge) from your engine oil system and protects against engine damage from blocked up oil channels and holes. This is chlorine, phosphate, nitrate and heavy-metal free and is to be used if black sludge is suspected, in the case of piston ring compression loss and for hydraulic valve rattle. To use, just add to your engine at operating temperature before changing oil. Ensure oil level is at least at minimum level. Allow engine to run for at least 30 minutes with idling rpm. Perform oil and filter change immediately! After cleaning, fill up with fresh oil and allow the engine to run for some minutes. 1 can is sufficient for 3-6 litres of oil.
