How to use Sea Foam for engine storage and stabilizing fuel


  • Stabilizes stored fuel up to 2 years
  • Helps fuel resist evaporation
  • Preserves ignition vapors
  • Adds protective lubricity
  • Prevents gum & varnish formation


  • Add at least 1 ounce of Sea Foam for each gallon of tank fuel.
  • Run the engine long enough for the treatment to work through the entire fuel system.
  • When possible, adding more Sea Foam when the tank is low will increase the cleaning and lubricating ratio when working the treatment into the engine. You can always fill the tank with fuel after preparing the upper engine areas for storage.


Sea Foam Motor Treatment works to stabilize stored fuel up to 2 years. Adding Sea Foam to stored tanks helps fuel resist evaporation, preserves ignition vapors, adds protective lubricity, and prevents the formation of gum and varnish in fuel systems. Gum and varnish residues are the most common cause of poor engine function. Using Sea Foam in stored fuel will help your engines start easier and last longer.
