The Carbon Guard additive is a gasoline additive formulated to minimize carbon deposit build-up in 2-Stroke and 4-Stroke marine engines. Add Carbon Guard to the fuel tank each time you add gasoline.

For 2-Stroke and DI Engines - add 1 oz. of Carbon Guard for every 8 gallons of gasoline (this 12oz bottle will treat 96 gallons of fuel).

For 4-Stroke Engines - add 1 oz. of Carbon Guard for every 16 gallons of gasoline (this 12oz bottle will treat 192 gallons of fuel).

It is recommended that oil be changed on 4-Stroke engines after an application of Carbon Guard. 2-Stroke engines with an excess of 100 hours of operation and not previously treated with Carbon Guard should be treated with Engine Tuner (click link) before beginning use of Carbon Guard.

  • Reduced possibility of piston ring sticking
  • Reduced carbon build-up in 4-Stroke intake valves
  • Better overall engine performance
  • Increased engine life
