Can you add Sea Foam to less than half a tank of gas? [SOLVED]

Hi Louis,

Yes, you can add it to less than half a tank of gas. In fact, adding a full 16 oz can to a low tank is a very efficient and effective way to use Sea Foam. I like to wait until the tank is low (1/4 -1/8 tank), add the whole 16 oz can, and then drive for at least 10-20 miles before refueling. It’s safe to add a high concentration like that and it works very well for cleaning fuel residues and deposits. Add it to fuel like this every 3,000 miles or once a year.
