Highly concentrated advanced engine cleaner. Effectively cleans engines, hydraulic systems, gearboxes and differentials. It is recommended to use before the oil drain and while the engine is warm. Add the entire content into the engine (1 bottle of 300 ml EVO Engine Flush will treat 5-6 liters of oil). Start the engine, let idle without load for 20 minutes, or drive 15 km. For manual transmissions and differentials it is adviced to add a maximum 4,5-5% of cleaner to the oil.
