How much Sea Foam in a 1965 VW Beetle [SOLVED]

Thanks for the question, David.

For cleaning, add at least 2 ounces of Sea Foam per gallon of fuel. A higher concentration is safe and very effective – I like to add a full can to a low tank (1/4 to 1/8) and drive until almost empty before refueling to give the Sea Foam time to work. Works very well to clean at that concentration.

For storage, add 1 oz of Sea Foam per gallon of fuel and drive a few miles to let the treated fuel work through the whole system.

Hope that helps!
