Should I use one can or two cans in a 26 gallon tank in my Jeep Cherokee? [SOLVED]

Hey Bill,

Thanks for the question!

Yes, you’re on the right track! Sea Foam Motor Treatment is safe to use in your 2021 Jeep Cherokee V6. How much to add depends on whether you’re trying to clean the fuel system or simply maintain it.

For preventative maintenance, use 1 oz of Sea Foam per gallon of fuel. With your 26-gallon tank, two 16 oz cans would be a good amount. You can add them now, even though you just filled up.

For cleaning, I’d recommend waiting until the tank is low (about 1/4 tank or less), then adding a full 16 oz can of Sea Foam. Drive at least 10–20 miles before refueling. The higher concentration works much better and faster to clean fuel gum, varnish, and other deposits than adding the same amount to a full tank.

With only 29,000 miles on your Jeep, regular preventative maintenance is a great way to help keep the fuel system clean.
