RZ20E Engine Flush, 300 mL

RZ20E Engine Flush is a professional-grade synthetic cleaning additive engineered to dissolve and remove stubborn gum, varnish, and sludge deposits from critical engine components including valves, piston rings, oil pumps, and galleries. Its non-corrosive, elastomer-safe formula protects rubber seals, gaskets, and plastic parts while restoring compression, reducing blow-by, and lowering harmful emissions. It enhances fuel efficiency, recovers lost engine performance, and extends engine life. Compatible with all gasoline and diesel engines—including turbocharged, direct-injection, and Euro 6-compliant units. Meets European OEM standards and is applied directly into the engine before oil change at a rate of one 300 mL bottle per 5 liters of engine oil.
