What are the ingredients in Sea Foam? [SOLVED]

Sea Foam Motor Treatment is made with 100% safe organic petroleum ingredients that work to clean and lubricate. It does NOT have harsh detergents or abrasive chemicals that can harm your engine or fuel system components. In summary, it’s a blend of three petroleum cleaning and lubricating oils that work together as a cleaner, lubricant, and to stabilize fuel.

Would Sea Foam Motor Treatment in the gas tank cause a chemical reaction if added alongside gasline antifreeze?

Sea Foam is safe to use with other additives and wouldn’t cause a reaction with gasline antifreeze. Sea Foam is made with petroleum ingredients, so it doesn’t react with other additives.
