When should I put gas in my Ford F150 after I used Sea Foam Motor Treatment? [SOLVED]

Good question.

You can add fuel whenever you’d like.

Here’s what I like to do: Add a full can of Sea Foam to a low tank of fuel (1/8 of a tank or so). Then, drive until almost empty before filling your gas tank.

The high concentration of Sea Foam works fast and very well to clean.
