Engine Flush Plus is a specially formulated combination of additives and carrier fluid. In combination with the carrier fluid, the highly effective detergent and dispersant additives dissolve sludge and lacquer formers. All types of oil-soluble and oilinsoluble residues are brought into suspension and removed during the next oil change. An engine which has been cleaned of deposits and contamination and which is then filled with fresh oil not contaminated with old impurities can develop its full performance characteristics.
