Is it OK to add 2 cans of Sea Foam to a 15 gallon tank? My car is a 4.6L Mustang.
That’s a great question to ask David. Yes, you can add 2 cans of Sea Foam to 15 gallons of gasoline in your Mustang’s tank. At 16 ounces per can, that will create a minimum cleaning concentration of a little bit greater than 2 ounces per gallon.
