It worked so good in my Corvette, I put a can in my Tacoma's fuel tank this morning. Doesn't taste good with cranberry juice. Mix it with Red Bull for a real rush.

I've been reading about seafoam for a while here and just bought a couple cans. I filled the tank on the vette and added about 3/4 of a can. Jumped on the highway and took it up to a 100. I didn't see any smoke as others have described, but I haven't run any through the vacuum line yet. I'll put the other can in my truck. I'm curious to see if it has any effect.

The best way to introduce Sea Foam directly into your intake, is through the power brake vacum line. DO NOT pour it directly into the vacum line, as you are taking a chance of liquid locking your engine. Use a very small hose, and let the vacum suck the Sea Foam out of the can. Make sure your engine is warm when you do it. Once the can is empty, and your engine smooths out, go out and drive the crap out of it. Be advised....your exhaust is going to smoke like a forest fire until you get the crud blown out of your engine, but it'll clear right up in just a few minutes. Your neighbors are going to swear that your house is on fire...it smokes that bad, so be prepared.

I'm assuming that putting it in the gas tank will offer similar results as opposed to putting it in through the brake booster line, but the effects won't come to a head until the tank is empty right? So no matter where I put it, I'm doing the same kind of clean?

You shouldnt get smoke running it thru the gas tank... thats to clean the fuel system (pump, lines, injectors).
If you want to clean the carbon from the pistons, it needs to be more concentrated, ie - thru the brake booster line. THEN it'll smoke like crazy!
Also, some of you guys just need to read the freakin can.. it tells you all sorts of ways to use it.

This stuff is amazing!! I started out using it on my 94 Rodeo (179K miles), then my fiance's 94 Corolla (190K miles)...what a smoke show!!!! The neighbor came over and asked if I needed to borrow his water hose and fire extinguisher! 
Then after not blowing either of thosde two up I went ahead a put 1/2 a can through the brake vacuum line and the other 1/2 in the fuel tank. Did not smoke near as bad as the first two but WOW..what a difference in the throttle response and pick-up! Best $5.79 I ever spent on my 92!

Well I added the Sea Foam and got better than expected results. The car didn't smoke that much but the idle and the way the car runs is incredible!! The car used to have a rough idle and would act like it was stalling a little bit. Well after the Sea Foam it runs so damn quiet that unless you are pretty close to the car you can't even hear it running. Needless to say, the C5 is getting it done next week. The easiest way to use it is to poor it in the brake booster vaccuum line as mentioned. I pulled the hose off going into the intake manifold and then used a hose with a funnel attached. I suppose you could pull it off at the brake booster but then again that hose is a pain to pull off there. Using the Sea Foam actually made me feel like I did something worthwhile to the car without breaking something first.

you are effectively cleaning out the carbon from the engine. I use it every time before I change my oil (Land Rover). I buy 3 cans, one for the oil, one for the tank and one for the intake. You DO NOT want to run it in the oil more then 500 miles.
wonder if there is any association between people who only use 93 octane gas and use seafoam and notice huge results, as using higher than needed octane gas can cause really bad carbon deposits...

You'll only see smoke if you put it in the engine. Running it through the fuel probably wont show much smoke if any. A 20 year old V8 will have a ton of carbon built up in the engine and thats why so much crap is being blown out.

Have 149K miles.
Today I very slowly added 1/2 can into the intake via the brake booster line with RPM's at 1,500 and engine hot. The rest went into the gas tank. I shut it off and let it sit for 30 minutes. Started it up and saw a moderate cloud of smoke that quickly went away. No smoke after that. Took it for a good drive and felt no difference.

I put about a third of a can through the brake booster and a full can in the gas tank. I still have about 3/4 of the tank of gas but have been getting unexpected results so far. I seem to have lost about 3 or 4 miles per gallon, it idles very slightly rough when it was smooth before, and there have been about 3 times that it would not idle at all after restarting warm. It would start and run if I kept the RPM's up but die as soon as I took my foot of the gas then run fine once I got it going down the road a bit. I am not too concerned until I at least finish this tank of gas, just wandering what everyone out there has to say about this unexpected happening.

I put about 12 oz. in the tank and filled it up, then ran about 4 oz through the brake booster vacuum line. Most of the smoke you see when running through a vacuum line is the the seafoam itself burning off. It's petroleum based and you can tell by the color & smell. If your blowing dark smoke out your exhaust, then I'd attribute that to carbon build up burning off. If not, it's just the addititive that's smoking.
My gas mileage is also down on this tank, though I do a lot of city driving. I haven't noticed any miraculous performance increases, but that doesn't mean it's not working either. I'm still waiting to throw a can in my truck, where I think I might be able to notice a difference.
To the guy expecting seafoam to straighten out a car that's been collecting dust for a year, I think you're expecting way too much from a mechaninc in a can. And you guys need to read the directions. I believe the directions say 1/3 of a pint through the intake and about 1oz per gallon of gas. An entire pint treating up to 25 gallons, if I'm not mistaken. Recommended use is every 2-5K miles.

Uh, the directions are in English on the back of the can. At idle I put 1/3 through the brake booster line (it sucks it out of the can) and let it sit for 5 minutes. Restart.
I had a little white smoke. That is the carbon indicator in the top of the engine. The rest goes in the tank with a dab behind each ear lobe. The results are apparent in the quality of the idle.
Travis93: check the booster line for cracks or the little plastic deal it fits onto. It sounds like that has failed. It's not the Seafoam because I brushed my teeth with it and man are they white.

I've read this thread about and have some questions. First off I have a 84 with 57K on the clock.
Some people have mentioned about adding the Sea Foam through the brake booster. If I do that, what size hose can be used to pour it into the engine? It seems, to me anyway, that taking off the hose at the manifold and putting on one just for this purpose would be ideal.
Then adding the rest of the can to the tank. Do you have to be exact with this? The can says 1 oz to each gallon. What happens if I'm getting 1 oz to every 3/4 gallon of gas. Will that harm the engine?
Thanks,
Wayne
