Can I use Sea Foam in a 2004 Kia Spectra? [SOLVED]

Thanks for the question, Mark. Yes, you can use Sea Foam in both the fuel and the oil in your Kia Spectra.

In fuel, I’d recommend waiting until the tank is low, about 1/4 tank or less. Then, add a full 16 oz can and drive at least 10–20 miles before refueling. The higher concentration works much better and faster to clean fuel gum, varnish, and other deposits.

In oil, use 1 oz of Sea Foam per quart of oil, added 100–300 miles before your next oil change.

High Mileage Motor Treatment is also a great option as it’s a great cleaner for older vehicles.

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

Best,
Conner
