What is difference between Marine PRO and regular Sea Foam? [SOLVED]

Thanks for the question Tyler. Sea Foam and Marine PRO are similar in that each are made from 100% petroleum cleaning and lubricating oils. The difference is that Marine PRO is formulated to meet all the core requirements that marine engine owners want in a fuel system treatment – it cleans fuel passageways, lubricates, stabilizes fuel, and provides corrosion protection to upper engine areas. It does not contain alcohol, which is something marine engine manufacturers can be particular about. Hope this helps!
