Can I put Sea Foam in my truck’s gas tank after I filled it? [SOLVED]

If I forgot to put Sea Foam Motor Treatment in before I filled my truck’s gas tank. Is it ok to put it in after I’ve filled the tank?

No worries, Tonie. You can add Sea Foam at any time.

That said, here’s what I’d recommend: wait until you have a low tank of fuel (1/8 tank or less). Then, add a full 16 or 20 oz can of Sea Foam to your truck’s gas tank. Drive until almost empty before refueling with fresh fuel.

The high concentration of Sea Foam does a great job cleaning. It’s the best way to get the most out of a can.

Hope that helps!
