Thanks for the question!
A 65-liter tank is about 17 gallons. How much Sea Foam to add depends on what you’re trying to accomplish:
- For regular maintenance: Add about 1 oz per gallon, so roughly 17 oz (500 mL) for a full tank.
- For cleaning: Rather than treating all 65 liters, I’d wait until the tank is 1/4 full or less, then add a full 16 oz (473 mL) can of Sea Foam Motor Treatment. Drive at least 10–20 miles before refueling.
The higher concentration on a low tank works much better and faster to clean fuel gum, varnish, and other deposits.
Hope that helps and let me know if you have any other questions!
