Great question, Joe. You can add Sea Foam Motor Treatment to your gas tank at any time.
However, adding it to low tank of fuel creates a greater cleaning concentration. I like to add an entire can or two of Sea Foam when there’s less than 1/8th a tank. Then, drive at least 10 to 20 miles to take advantage of the higher concentration before refueling. That’s one of the best ways to use it! Hope that helps!
