Hi Joana. Adding Sea Foam to a 3/4 tank of fuel depends on how many gallons. If 16 or less, you can add a whole can. If more than 16 gallons, you either need more Sea Foam or can wait until there’s less fuel in the tank. What I do: I like to wait until there’s around 1/8th of a tank of fuel, then add a can and drive a bit to take advantage of the higher cleaning concentration. You also save money that way because you’re doing more cleaning with fewer cans over time. Hope this makes sense!
