How many ounces of Sea Foam to a 23 gal gas tank? [SOLVED]

Thanks for the question!

For preventative maintenance in a clean engine, our general recommendation is 1 ounce of Sea Foam per gallon of fuel, so for a 23 gallon tank that would be about 23 ounces if the tank is full.

For cleaning, I’d recommend adding more Sea Foam per gallon. Here’s what I’d do to get the most cleaning power:

• Wait until the tank is low (about 1/4–1/8 tank).

• Add a full 16 oz can of Sea Foam.

• Drive 10–20 miles (or as normal) before refueling.

The idea here is to create a high cleaning concentration, which works better and faster than adding a small amount to a full tank. It’s safe to do and very effective at cleaning fuel residues and deposits.

Hope that helps and let me know if you have any other questions!
Best,
Conner
