Thanks for the question, John. Here are the instructions for how much Sea Foam Motor Treatment to add to fuel:

  • For regular fuel system maintenance, add 1 ounce per gallon.
  • For cleaning, use 2 or more ounces per gallon – the more you add to fuel, the better it cleans! Add when the tank is low (1/4 tank or less) to maximize cleaning concentration.

What I like to do: simply add a full can of Sea Foam Motor Treatment to a low tank of fuel, and drive until almost empty before refueling. Using a high concentration like that is a great way to get the most out of a can of Sea Foam.

Hope that helps!
