I accidentally added Sea Foam Marine Pro to my diesel tank. What should I do? [SOLVED]

Thanks for the question, Kris. First off, there is nothing to worry about. Marine PRO is completely safe for a diesel engine. It’s not labeled for diesel engine use because the product was formulated for gas engines and the claims haven’t been tested in a diesel. That said, Marine PRO will still work to clean critical engine areas in your diesel. Go ahead and run it as normal.

In the future, you might be interested in Sea Foam Motor Treatment in the gallon container. You can find that at most auto parts stores.
