I'm not sure why. He said to add it to the manifold some how.
I had to cancel my appointment bc I'm going to do some mods first.

I add a little to a full tank(s) of gas when I 'store' the car in the winter.
Same with the boat and mowers/etc.
Excellent product IMHO.

My late father was a baker/pastry/candymaker and he used to make something called "Seafoam" when we were kids.
It was white, very light in weight when you picked up a piece, and very good.
Prolly not the same thing, and I never tried any in the gas tank . . .

That stuff was designed to be used in two stroke outboard engines.

I read an article awhile back about running stuff like seafoam through the Manifold with a little hose. Said stuff like that might clean the valves a little but would also burn out your Cats(and that's an expensive replacement). Seafoam was one on his list that would do that. Can use it like Staybill in the winter too.
Seamed to know what he was talking about on gas and engine additives by the chemicals they use. So I only run it through the gas. Everyone likes Textron? too, guess it does a good job.

You use a vacuum line to suck it up into the intake so it is dispersed to the cylinders. I run it in my 200k cobalt every so often in the intake, fuel, and oil. The smoke show is fun too lol

Yeah, I try to do it during the week so the neighbors don't call the fire department on me! I just did it on my 2005 Vert with 180k miles and cleaned the MAF and it smoothed out the idle. I am pulling the plugs after 10k in the morning to take a look but Seafoam has been around for some time.

That sounds like what my father used one time (Bardall) or something like that,,,that made huge clouds of blue smoke that filled the neighborhood.
I was thinking of maybe putting the seafoam into a spray bottle and spraying into the intake and see what happens. I have used the Techron in the gas tank, but I'm not sure if it really works that well.

the instructions says to pour it in the gas tank and gives the recommended mixture. If you would want to go with a heavier dose than recommended, just run the tank down to a couple of gallons and pour in the whole bottle.
I am not sure why any newer car really needs it but it can't hurt.

So it might need it. IDK

When I fished the BASS tournament trail they use to have demonstrations at the tournaments showing engines that had been run side by side, one cleaned with Seafoam and one without .. When they tore the motors apart the one with the seafoam was very clean , and the one without Seafoam had heavy carbon buildup....It's great for outboard motors , I'm not sold on it for car engines...WW

Two strokes?
I've known many 2-stroke OB boaters that have used it, and it does make a ton of smoke - but the jury is out on "what" is burning; Seafoam or carbon build up. But from what I've read and seen from limited internal inspection with a bore scope, it's not proven IMO. Most of the folks I know that used it had older 2-strokes, not the newer Erude E-Tec's...
My opinion, worth what you paid for it...
ETA; all modern fuels are required by law to have a detergent. And then there are the top tier fuels, and the best among the best. In a modern EFI 4-stroke OB, maintained properly and running properly, I doubt it helps or is necessary. If your burning Chevron or equivalent, you're running a constant dose of Techron at all times. Personally I doubt Seafoam can *clean up* anything more...UNLESS you have an older 2-stroke with an oil injection pump (or mixing your oil/gas).

I use it in stuff that I buy that's been neglected, typically these have smaller engines than a Corvette would. It's basically a detergent, like an ether or something like that. It cleans stuff up for sure, any kind of deposits it reaches it does a good job cleaning them out.
Sometimes, you don't want that. I bought an older seadoo that had fuel lines that as they aged would turn the insides to goo. It ran fine when I bought it, but after running the seafoam through it in the tank, the goop on the lines was loosened and found its way to the fuel filters in the carbs. Had to clean those out and replace the old fuel lines. Now, this wasn't the seafoam's fault, it was a relic of the days when gasoline was just gasoline, the seafoam just unintentionally cleaned it some.
I think it's good stuff. Does a good job of what it's designed to do, on higher mileage cars it's not a bad idea to add a bit to your oil before an oil change every few years. Especially cars that sit.

Used it all the time in my old 300m Chrysler. Seemed to be effective. Tried it in Jaguar XJ8 and it was followed with engine codes about lean engine mix and such. All went away when the stuff burned out and had a few tanks of pure gasoline. I no longer use additives.

Use it!
Use it in motorcycle and all the cars; gasoline additive. Usually wait for it to go on sale (e.g., $7-$8/can) and then stock up since "retail" is kind of high.
I've heard of people putting a can into the crankcase right before an oil change to help clean out oil channels, etc.. (Haven't gone that route yet...).
