I would not use Seafoam as a fuel stabilizer, and I do not believe claims written on labels. It is proven they will put anything on a label until somebody sues them for misrepresentation, and the only ones who profit from that are the lawyers. So there seems to be some collective understanding between competitors to just let sleeping dogs lie and milk the consumer with clever marketing and outlandish claims with no substance to back them up.

In fact with the content of Seafoam being a good percentage alcohol, I will no longer put any into my tankIn fact with the content of Seafoam being a good percentage alcohol, I will no longer put any into my tank, though I have in the past without issue. Running it through the intake did seem to clean up the Idle a bit, but subjective seat of the pants "butt Dyno"s are hardly Scientific, especially with the human mindset of expecting results from effort or money expended.

Of all the Automotive forums I peruse, there are more fanboys of Seafoam here than anywhere else. On Other forums it is almost a despised product, so I find it amusing to come here and see it praised by some as the holy grail to engine maintenance.

I hate it when people who are not qualified start spouting.
I have been an ASE master tech for 1/4 century.....it works.
Now to prove your inaccuracy, the MSDS for seafoam shows 10-20% IPA which btw stands for Isopropyl alcohol. So it is REALLY made up of mostly other stuff. Seafoam MSDS

Would this be a better choice for my 454 tbi engine?

I have used Seafoam in everything I own at one time or another. Not once has it ever caused a problem. I've seen it clean out carburetors in lawn equipment, ATVs and outboards to the point where they run much better. It's one of the only "Tune up in a can" products I would ever recommend.

B.O.

I am of the opinion that an urea based additive TECHRON in particular or Shell's "Nitrogen Based" gasoline additive is the only consumer chemical that actually does anything at all inside the combustion chamber. Other additives are mouse-milk they remove something all right.

Money from my wallet for nothing...

I have run it in my boat the last few year (seafoam), had to replace a fuel pump and a bunch of other stuff. The dealer had a notice on the wall with pictures to stop using it!

This always cracks me up. So what is going on the Seafoam is breaking off "chunks" and sending them down the fuel line. Or is it taking hard "stuff" and turning it into molasses then sending that down the fuel line plugging up things.

Urban Myth is all they are pandering. Last thing they want is a $9 can of Seafoam fixing their $300 plus repair job.

The Seafoam didn't create your problems, age and bad fuel did. No way a cleaner can take out a fuel pump. That's just silly.

I dont run ethanol in my boats. I guess you are a seafoam rep or something. Why Would the dealer put a service bulletin on the wall warning people to not use seafoam?and the mechanics warn me about it. I did not have any problems till a year or so after using it! You do what you want, When you have problems you will know why

. Dont be a A$$ unless you are an engineer keep your pie hole shut I will ask if I want your opinion. Just like the OP did, he wanted to know our experiences.

yep, the use of fuel containing alcohol does a lot more damage.

Back when they switched to ethanol everybody had clogged fuel filters -- if your gas tank or fuel lines were gummed up they have likely been already cleaned by the ethanol so Seafoam isn't going to create that issue.

if you run it through the intake it will clean the valves a top of piston of carbon fouling which in turn will get rid of hot spots in the cylinders an you will get better combustion (ie) better mileage plus it cleans the intake manifold
