This stuff works great - go to YouTube and check out ChrisFix's video about it. This quantity is more than the average consumer needs, but it really helps reduce carbon buildup in your engine.
Or put decent gas in your car and don't waste money on something that is chemically impossible.
There are two ways to remove carbon: heat it up until it combines with something else (usually oxygen) or physical removal.
Sea Foam will remove glazing caused by poor oil maintenance and inefficient combustion. But then again, that's how the carbon got there which circles around to proper gasoline and engine maintenance. And in the mean time, you're burning the oils in the product which is what causes the smoking from using this stuff.
Or get an additive that has something in it that actually does something.

Really? I didn't find the results of any of his product tests at all impressive. We keep our cars for decades, use the correct fuels and oils per owner's manuals, change oil and filters at the prescribed intervals and have never had any carbon-related issues...ever. None of us ever use any extra "additives". In life, one should try to separate the psychological desire for control from reality. It's the same thing that fuels the "supplement" market...hope and placebo effect.

Take your engine apart & look for carbon deposits.
Ummm, correct oil and/or gas does nothing for direct injected engines. With that said, neither does sea foam. Don't go see a Doctor, just ask Ben for advice. It's legit, trust me.
It's not a miracle cure but can help. How does that carbon get upstream of the cylinder, before the intake valve(s) are gunked up enough to leak? The PCV system, pulling oil vapors back through the engine.
Those vapors are not YET carbon, more of a tar until they bake on at valves, or oxidize further upstream. Seafoam dissolves that, which is a primary cause for smoke out the exhaust using it.
No amount of vehicle maintenance changes this. You could call taking the entire intake apart and cleaning it plus the back sides of valves "proper maintenance" and it'd be more thorough if done correctly, but it's also a lot more work, and/or expense if you're paying someone to do it.
You may say "I've owned vehicle x for many years and never needed to do it". If you've owned it that long, odds are it isn't direct injection, and odds are it gradually reduced in performance and fuel economy and you just chalked it up to what happens to a vehicle as it ages.
Certainly other factors contribute to reduced engine performance over time and there's no magic in a bottle that will restore an engine to new condition, but many people have demonstrated that it reduced buildup, especially nearer the PCV entry point. Here's a pic of a PCV line nipple before and after Seafoam was fed through that hose:
If you prefer to manually clean, go for it, but know that many engines now need the upper intake taken off as well as many things around it just to get to the PCV line, though that also makes it a PITA to put seafoam in there.
In a modern direct injection engine it's much more effective to add a good quality oil catch can, and in many cases instead of seafoam you could just spray kerosene and gas into the intake, but whatever you add, don't do it before the air metering sensor.
