Seafoam isnt really an oil product, its a multipurpose cleaner.
To me Lucas oil stabilizer is just an oil thickener.

I run seafoam through my intake about every 10,000miles and it seems to help it idle smoother(i assume its from any carbon that was build up on the valves....). Anyways I had the intake/exhaust manifolds off my inline six that has 160,000mile on it to replace a core/freeze plug. The inside of the manifolds were incredibly clean unlike most of them i have seen off of high milage vehicles, for me this is enough proof that seafoam removes carbon buildup in engines.

Seafoam is not supposed to fix leaks or anything so i dont see how its a "fake" product such as aftermarket octane boosters.
