You'll always find Marvel and Seafoam on the shelf in my garage.
Never used sea foam
What would it do for my car ?
tox, I've no idea, and really, no proof.
I ran it thru the brake booster, and boy, did that thing buck and kick and fart black filth.
My guess is that the exhaust funk gets gummed up in the cat.
I'm not daunted, I swear by the stuff.
To me, this translates to "only attempt this with a well warmed engine, and don't introduce the magic juice too fast"I had that thought, although once at operating temp with some air it should burn off that stuff, that's what it's supposed to do. Unless the filth had a bunch of metals content, that would be bad. Or mechanical damage if it backfired? It's a ceramic honeycomb, somewhat delicate.
I asked my mechanic about SeaFoam; he said it was overrated and overpriced. He recommended a bottle of Techron once a year in the fuel tank. He also used Techron to clear out a plugged-from-lack-of-use fuel injector in my mom's Crown Vic.

So, what does Marvel Mystery Oil do? I have only used it as a lubricant so far.
I have heard that it could be damaging to higher millage engines that never had sea foam treatment before. Apparently sometimes carbon buildup can help with compression on a worn engine.
