 I put a $10 bottle of SeaFoam in my gas tank. Is it supposed to do anything?

Have a Toyota with 65k that I've never put any kind of gas additives in. I know SeaFoam has been mentioned on here a time or two so I picked up a pint.

Is it supposed to do anything or is it just expensive fuel injector cleaner? Speaking of which, does it even make sense to buy fuel injector cleaner? Seems expensive for a little bottle.

I dumped a bottle in a Chevy once with about that many miles.

Ran rough for a short while, seems I saw a little smoke. Then things smoothed out.

Did it again later and there was no reaction at all.

At worst, I don't think it'll screw anything up.

You're supposed to suck it in the vacuum tube and shut the motor off. Let it sit for 15 minutes and then fire it up ad burn all the smoke out.

In the tank = expensive bottle of "injector cleaner."

The problem you have is that you paid $10 for a bottle of Sea Foam.

"Dumping it in the gas tank" doesnt do much.

Pour about 1/5 of the bottle into the vaccuum line from your Brake Booster. That will really clean some shit out of your system.

The proximal effect is that it makes your wallet $10 lighter.

I'm asking about the distal effect.

I don't understand why you put quotes around injector cleaner.

I know guys do it, but I have never felt any desire to clean my engine by pushing contaminants through the combustion chambers.

I threw it in my GS750 that ran OK, but was a little rough on startup. After two treatments (two tanks with half a bottle) it was a major improvement. I threw it in the VW I'm working on in hopes it will clean up/clear out things before I have time to tear apart the carb and other things.

The bottle had directions on it. It said to pour it in the tank, which I did.

I'm just wondering if it's supposed to do anything.

I'm guessing it will be a non-event.

It's more effective if used in the vacuum lines, as stated above - putting it in the gas tank won't really clean much.

SeaFoam is used to solve a known, specific problems. Using it just for laughs has the potential of causing unintended degradation of non-metal seals, gaskets, hoses etc.

First of all at 10 usd a bottle you got white boy'd on the seafoam. Our last seafoam thread went 9 pages. Not much new from seafoam r & d.

I drive a 2000 Mustang. The 2000 model has a design flaw that allows small traces of oil to be sucked up into the engine by way of the PCV system. The oil burns and collects over time and causes premature detonation of fuel. Seafoam cleans it out. I'm overdue for a run through. I'm gonna do it tonight I think. Ford has "prescribed" a similar product of their own to fix the problem IIRC.

Guys on one of the Land Rover forums use it to clean out the injectors and such.........they swear by it. Could be that it does something for that particular motor (only look at the stuff on Disco 2's) or it could be that they are just a bunch of ninnies. I've never tried it, but they have been spot on with every other problem I ever needed help with..........

My '04 accord threw a code 2 days ago, something about a catalytic converter. The advanced auto guy said to give a pint of seafoam a shot, run through the whole tank and he'll reset the code and see if it pops again. Hell, it's worth a shot over a trip to the dealership!
And to tell you the truth I don't care about the cat as we have no emission testing in my county so as long as its just that I don't care.
I just don't like seeing the check engine light on

My old pathfinder was throwing a code for a "leaky injector" i put a can of seafoam in the tank and the check engine light went out by its self.

Meh. Do it right and have a shop do a BG fuel system treatment (fuel and fuel pump are disconnected, engine runs on the solvent itself, fuel pressure is provided by shop air). You'll never do better than that, short of disassembling the engine.

To echo a poster above, SeaFoam is best used for problems caused by carbon and oil build-up and is most effective when sucked through a vacuum line. I've put some on a rag before and used it as a cleaning solvent on dirty engine parts like intake manifolds and it seems to work as well as any other good solvent. If you're cleaning individual parts, SeaFoam is certainly not the most cost-effective solvent in that regard, but on an assembled and running engine, you have the peace of mind knowing it won't harm sensors, seals and gaskets. Where I've had the most success with it, is clearing out idle issues where carbon and gunk make idle air controllers sticky. I've never added it to engine oil, but I've heard others claim it helped with sticking lifters.

the seafoam would have worked if you hadn't dumped it all in the gas tank. Go buy another bottle and suck it down a vacuum line

I've put additives/boosters in two different high mileage vehicles over the years. In each instance, shit got fucked up within one oil change worth of mileage.

I don't put shit in my gas tank anymore.

I like Turtles Techron, it has lots of fans on the Honda V4 mailing list.

How a four-carb, high RPM motorcycle engine compares to a Toy Oater, well, I'm not sure.

I would agree that it did what it was marketed to do: Seperate you from your money.

OP, you're fine. There are 3 ways to use seafoam. One is to put it in your gas tank to help clean the fuel system/injectors. This can help clean out injectors and gunk but isn't that ovious when it works unless there is a problem. Decent preventive maintance though and maybe it will clear up something you hadn't noticed before.

Second way, and the one that most people hear about, is to slowly put it into your intake manifold by letting it be slowly sucked up by the vacume line while the engine is running. Then you turn off the engine and let things sit for a bit(15-60 minutes depending on who you talk to). After that you start up the car and rev it a bit and your exaust will likely be really smokey as it burns out all the carbon and gunk that the seafoam loosened up.

A third way is to put a little bit into your oil right before an oil change and drive with it in there for a certain time period before you change your oil to help clean out more stuff.

You didn't hurt anything, and you might have cleaned the injectors a little, but other than that, not much.

When I worked in the auto biz we used GM top engine cleaner, and we'd do it at night to help hide all the smoke pouring out the exhaust. Doing it in the daytime was a guaranteed ticket if a cop saw it.

I have always used Diesel fuel for oil additive.. Just never leave the shop with it that way

It will clear out some crap left by EGR and PCV shit. I run it through the brake booster.

I ran two treatments thru the brake booster/PCV and one in the fuel tank of a 2001 Toyota Tundra with 176k miles.
Smoothed out the idle, cured hesitation, runs noticably better. Worked like a charm for me.

Might help clean injectors a bit, which is not a bad thing. It's also a very good gas stabilizer and can be used as such.

No, not really.

With regards to injector cleaners in general, IMO, fuels nowadays really have all the cleaners and such in them you really need. There are a handful of additives that do work, such as Chevron Techron or TEC 2000, if you wanted something to dump in your gas tank.

Works well as an injector cleaner, It really fixes the wife's truck's poor starting issues.

Where it really shines for me is in 2-stroke motors. It's brought more than a few chainsaws and outboards back from the dead.

You must use a crazy ratio of foam/fuel.

I buy busted equipment and fix them. I then sell them on Craigslist.

9 times out of 10 it's as simple as replacing the spark plug and running straight Seafoam thru it to soak for a bit.

No, I don't think so. It may give you the placebo effect that it's doing something, but no, I don't think it's really doing anything.

ETA - Point being, you've got some kind of deeper root problem that needs to be fixed. Address your base concern, and you won't need any cures in a can.

What this guy said...

Disagree. I have a 4 banger that is supposed to get decent mileage but has had 18-24 mpg consistently since the day I bought it. I put in seafoam a couple of weeks ago (into the tank because I couldn't figure out which vacuum line to yank) and my mileage went up to 33/29 mpg on the last two tanks, with AC, driving both highway and city.

I haven't seen that in 2 years.

Next to go is the fuel filter. When I bought the car I had two tanks of 40+ mpg. Don't know what happened there.

A pallet of seafoam no longer in your trunk?
