It ensures that the carbon, soot and dirt accumulated in the engine, that pass through the oil filter, are removed from the engine with the old oil. It circulates everywhere where the oil circulates, such as the crankcase where the engine oil is stored, the oil pump, the oil intake chamber, the camshaft lubrication channels, the turbo lubrication channels, and cleans the oil deposits and mud. As a result of this cleaning, the new engine oil to be placed in the vehicle can easily travel through the entire system and provide maximum protection and function. It eliminates the performance losses caused by the piston rings getting stuck due to the dirt inside the engine. It is recommended for all engines, diesel, gasoline, with or without catalytic converter, with or without particulate filter, atmospheric or turbocharged. Compatible with synthetic, semi-synthetic and oils.
