Marvel Mystery Oil top cylinder lubricant gas and oil additive. A light-bodied friction reducing, wear-resistant, heat-resisting additive which produces no carbon or gum but a lubricating residue in combustion motors. Presents sticky hydraulic valve lifters and counteracts harmful combustion residues. Mystery Oil combats internal motor rust and corrosion, lubricates valves, piston rings and upper cylinder walls and eliminates valve sticking. Keeps rings free and reduces piston and cylinder wear to a minimum. Also keeps fuel pump and carburetor parts clean, eliminating need of frequent adjustments. Mystery Oil retards formation of power-dissipating motor deposits
