Highly effective engine cleaning treatment designed to remove harmful sludge, varnish, carbon deposits, and other contaminants from the engine's internal components. Its advanced formula dissolves both oil-soluble and oil-insoluble residues, suspending them in the engine oil so they can be completely drained away during the next oil change. Once the old deposits are removed, fresh engine oil can circulate freely, helping restore optimal lubrication, improve engine efficiency, reduce internal wear, and extend overall engine life.
