I use it but honestly see it doing nothing as a stabilizerThe OEMs recommend it for storage and cleaning the fuel system. We've been over this several times, so now it is officially a memory problem.
Unless you find a way to prove it to yourself, it remains part mystery and part old wive's tail lolCopied from the internet, "Seafoam, per the current MSDS, is 40-60% Pale Oil (CAS 64742-54-7), 25-35% Naphtha, and 10-20% Isopropyl Alcohol "IPA"."
I sometimes buy it when it's on sale but I assume it's mostly snake oil.
Agree it's a cleaning agent but not fuel stabilizerI did not believe in (Mechanic in a can fixes), until I was convinced to try it, it's plain and simple, it works! I have seen it smooth out rough running engines, and remove carbon from the back side of intake valves. It keeps carbs and injectors clean. Like I stated, It Works!
