What is the best ratio of Sea Foam Motor Treatment and fuel for my gas tank? [SOLVED]

That’s a great question Ryan. Here’s what I do: I always try to add a full can of Sea Foam when the tank is low, then drive at least 20 miles with a higher concentration. For example, if I add 16 ounces of Sea Foam to three gallons of gas, my ratio is 5 ounces per gallon. If I add a can to 2 gallons, it’s 8 ounces per gallon. Once I’ve driven 20 or so miles I will add more gasoline, but won’t let the ratio go less than one or two ounces per gallon. As the can instructions show, add 1 ounce per gallon for fuel maintenance…add 2 or more ounces for cleaning.

How much sea foam do I use in a Gallon of gas

Hi Mark – add 1 oz of Sea Foam per gallon of gas for routine preventative maintenance and stabilizing fuel.

If you are using it to clean out a fuel system, it’s safe and effective to add a much higher concentration. I like to use half of a can (8 oz) in a gallon for cleaning.
