How much Sea Foam per gallons of gasoline? [SOLVED]

Thanks for the question, Blaine! Here’s an overview. It depends why you’re using it:

• For preventative maintenance/fuel storage: 1 oz per gallon
• For fuel system cleaning/overcoming a fuel-related engine problem: 2 or more ounces per gallon. To maximize cleaning, add a full can (16 oz) to a low tank (2-3 gallons) and drive until almost empty before refueling.
