Rzoil Oil System Cleaner - 300 ml

This oil system cleaner removes deposits and dirt, helping to restore engine performance. It remains in the engine oil for up to 400-1000 km, reducing oil contamination and supporting both petrol and diesel engines (turbocharged and non-turbocharged). To use, add the cleaner to the old oil before an oil change, drive the vehicle for 400-1000 km (or for one to two weeks), then change the oil and filter. In cases of heavy deposits, it is recommended to change the filter as well during operation.
