As motor oil degrades between changes due to heat, pressure and contamination, internal engine parts can become coated with sludge and varnish. These deposits can reduce fuel economy, restrict oil flow and cause premature wear in an engine.

MOC®’s unique cleaning solution and oil supplements gently dissolve sludge and varnish deposits and fortify new oil against oxidation and enhance its protective qualities.
