Seafoam also works well for 2 cycle engines.
When I leave fuel in my chainsaw, trimmer, blower and so forth it gums up in the carburetor and they get hard to start. I don't even measure; I just pour the stuff in and the engines respond nearly immediately. Saves rebuilding the carburetor.
Be careful using it in direct injection engines such as modern diesels. If you used it or something similar since the car was new it is ok. But if you have 150k on the engine you will probably give it a heart attack when the seafoam loosens the crap that is built up on the walls of the fuel lines and breaks free and clogs the injectors. If you have a duramax, it is a $4500 repair bill.
Happened to me when one of my mechanics decided to clean the injectors of 4 of my topkicks.... All 4 of them clogged.
I recently bought a 16 oz can of SEAFOAM...thinking about adding the whole thing into my gas tank, instead of putting some in vacuum hose that leads to the engine, adding some to the crankcase oil and a little in the gas tank like some suggest...I may just add all of it to the gas tank....would that be a bad thing?
Can seafoam hurt anything?
Nope. been Seafoaming both ways ever since 2001 or 2002, do not remember exact year. Through quite a few cars actually. Recommended to many online and had many thank yous.
Out of curiosity, I drove my then Range with Seafoam in oil for 2500 miles. No problems.
So, OP, from real life user for years, with great success, not a "I went online read this and that" opinion, go for it. Seafoam is great product. So is it's sister product, Transtune.
Prime fuel system once a year with can. I pour seafom into crankcase about a week worth of driving before oil change. My engines run like Swiss watches.
I also did use it in combustion chambers, to reduce piston rings carbon build up. THAT is an interesting experience, as then you have military grade smoke curtain coming out of tailpipe and covering entire hood. So be aware of that. But nothing adverse happened to engine.
In theory, I don't think 1 bottle is enough. It has to be used regularly to work. Older Cars that have deposits build up require regular use of seafoam and gas with detergents to make a difference. It takes time to completely remove the deposits.

Can you read what it says on the can? On the side of the can it says how much to use for maintenance and for a "clean-out" dose.
Any sort of additional detergent does compete with whatever extreme pressure additives you have in your oil (additives that the oil manufacturer put in the oil, not anything you added). If some is good, more is not necessarily better.
Various clean up products can and do work *if* your problem is a dirty or gummed up fuel system part. If the fuel system is clean, and you have say a vacuum leak, they won't do anything about that.
It's sea foam it can't hurt anything because it doesn't really do anything. That stuff along with WD40 is not allowed in my garage.
You don't allow WD40 in your garage?
What next are you going to tell us? That you don't have any Duct Tape, too?
(BTW, WD40 makes a GREAT bee/wasp/hornet killer... ) and once on the ground, you can hold them captive with the duct tape...
