Is Sea Foam safe for aftertreatment systems on Cummins Diesel engines? [SOLVED]

Thanks for the question, Bob. Sea Foam Motor Treatment is NOT for use in a diesel aftertreatment system.

Additionally, Sea Foam Spray is NOT safe for diesel engines. Sea Foam Spray will run a diesel engine without diesel fuel present. The chances of a diesel runaway is too great. We do not recommend using Sea Foam Spray on diesel engines or equipment.
