MATHY-C is a newly developed and highly effective engine cleaner which is used for flushing and cleaning petrol (gasoline) and diesel engines. MATHY-C can also be used with catalytic converters and turbochargers.

This engine cleaner is particularly effective in removing sludge deposits (black sludge) in the engine. Special cleaning additives dissolve deposits and dirt, which can then be drained with the engine oil during an oil change. Your solution if you missed an oil change.

The engine cleaner ensures a gentle and fast cleaning. MATHY-C does not affect the seals and shows full effect after just 10 minutes.

The contents of one can (400 ml) is designed to clean an engine using up to 5 liters of motor oil.


Add MATHY-C to the warm motor oil right before the oil change. The oil level must not fall below minimum. Then the engine should run for a few minutes, the maximum cleaning effect is achieved already after 10 minutes. After using MATHY-C immediately change oil and oil filter. After using MATHY-C engine cleaner, we recommend using our motor oil additive MATHY-M. It prevents the formation of deposits and increases the reliability of the engine by reducing wear and abrasion.
