No solids or other harmful ingredients
Will NOT change lubrication viscosity or other additive packages

HMS Engine Treatment is an extreme pressure lubricant that starts where other lubricants leave off, by conditioning and penetrating the metal of your engine, not the oil. The treatment actually penetrates the metal, smoothing the microscopic irregularities, cracks and points of uneven wear on the surface of all metal surfaces. All metal parts that are lubricated are treated and conditioned.

HMS Engine Treatment is designed to counter the damaging effects of friction, significantly reducing heat buildup and wear and extending the engine service life. This lowers maintenance costs and down time. HMS Engine Treatment also cleans moving parts which are hindered by the buildup of sludge, gum and varnish due to lubricant breakdown or a lack of maintenance.

HMS Engine Treatment is exclusively formulated to blend with petroleum and synthetic oils, gear lubes, and grease. It contains no solids and will not cause any material buildup or change even the finest of machine tolerances.


  • Improves fuel mileage
  • Eliminates “dry” starts
  • Prolongs the life of the engine, gear box and differential
  • Protects the moving parts against heat and friction
  • Increases acceleration, horsepower, torque and performance
  • Penetrates the metal surface to form a polished shield that reduces friction
  • Removes accumulated contaminants


GAS & DIESEL ENGINES: Add one 8-oz. bottle every 12,000 miles. In larger applications a 1:16 ratio is recommended. Contact your dealer for further details.
