Engine decoking agent ML202 is a classic liquid formula for decoking the cylinder-piston group. The composition is suitable for cleaning all types of gasoline and diesel engines that have been diagnosed with coking symptoms for the first time or recently. It has a high penetrating ability and a gentle effect: after using this decoking agent, the engine can be operated at higher speeds. Effectively eliminates such problems as average excessive oil consumption, reduced power, deterioration in dynamics and throttle response, increased fuel consumption, and differences in compression in the cylinders. The product is recommended for use in regular operation in urban traffic conditions. The exposure time varies depending on the degree of engine contamination up to 12 hours without the risk of damaging rubber seals, oil pan paint, and antifriction coatings of the cylinders.
