Sea Foam in a Detroit tractor [SOLVED]

Thanks for the question, Arthur!

Here’s what I’d do if you’ve never used Sea Foam in the tractor before:

Start by adding a high concentration of Sea Foam to a low amount of fuel (4+oz of Sea Foam per gallon of fuel). Run it at least 20 minutes before refueling so the Sea Foam has a chance to work through the system.

After that, add 1 oz of Sea Foam per gallon of fuel every time you fill up for routine maintenance.

You can also add Sea Foam to oil (works great to clean stubborn deposits). Add 1 oz of Sea Foam per quart of oil when you’re close to your next oil change.
