Anyone use Sea Foam motor treatment? If so, what were the results? Also any unexpected issues?

Seafoam is outdated. I switched to Royal Purple years ago.

I use Sea Foam in my T-Bird and my boat every time I fill up. I have never had any adverse reactions. Both vehicles continue to run great. Don’t know about it being outdated….

Don’t know about it being outdated….

Like they say, you learn something new everyday! Royal Purple is better for maintenance.

Sea Foam is a petroleum-based blend (pale oil, naphtha, and isopropyl alcohol) rather than a pure detergent.

Royal Purple: Is a detergent-based additive that
Contains high concentrations of Polyether Amine (PEA), which survives high combustion temperatures to scrub away carbon.

On a side note, Seafoam is preferred for engines that are gummed up or have been sitting for a while vs maintenance.

You learn something new everyday. I have Royal Purple in my Amazon Shopping cart to give it a try.

I asked GROK AI to review things looking at both "reviews" and at the MSDS info. Below is what it came up with. For the PEA ones, they work best under "city" driving where you get cycles of warm up and cool down. It gets into the deposits and works on them while the car is not running. If you put it in just before driving cross country you don't get nearly as much benefit because there is no "sit" time for it to work before you have burned thru all the treated fuel.

GROK: After reviewing available data on popular fuel additives, Chevron Techron Concentrate Plus stands out as the top performer for cleaning fuel injectors, intake valves, and combustion chambers. It uses PEA, a highly effective detergent, and has strong backing from independent tests and real-world user results. Red Line SI-1 follows closely with one of the highest PEA concentrations among additives. Royal Purple Max-Clean also shows good carbon removal in soak tests and earns solid user feedback for smoother engine performance. Seafoam is a versatile option, excelling at moisture control and general cleaning, though it's more solvent-based than a heavy PEA formula.

Royal Purple Max Clean also has a fuel stabilizer, which is not included in the Chevron product. Royal Purple is a great company across the board. I use the synthetic rear differential gear oil in my Mustang. Both are detergents and a better option than petroleum-based Seafoam for routine maintenance.

Also worth nothing, they both help clean the carburator as well.

I just asked Grok too and it suggested to alternate between Royal Purple and Chevron which is a great idea!
