MARVEL MYSTERY OIL

Marvel Mystery Oil can be added to gas or diesel engines and lubricated all the fuel system-fuel pumps, fuel injectors, carburetors and cylinder tops. It reaches areas in an engine that motor oil does not and extends the life of these areas. It prevents varnish and gum build-up and reduces accumulated varnish and gum residues. It also prevents oil from congealing in low temperatures and creates a clean burning cylinder environment which reduces carbon build-up of spark plugs. Not for use on diesel engines 2007-date. Available in pint or gallon containers.
