Hi Keon. Sea Foam is always safe to use in fuel no matter how often you add it to your tank. One tip is to add Sea Foam when the tank is low in order to create a higher cleaning concentration. What I like to do is add Sea Foam when I have around 1/8th of a tank, then drive at least 20 miles before filling up.
