Title: Does Seafoam Actually Work? (with Proof)
Post by: Rugby_fxdwg on March 07, 2015, 07:13:27 AM
Has anybody watched this on You-Tube? I've been utilizing this product for years before each oil change i will run the appropriate amount through with a tank of gas. When the bike is HOT I will spray some threw a windex bottle into the Carb.... If im doing this wrong please let me know.... :oops:

I use Seafoam in pretty much everything.  As they say "The proof is in the pudding."  :up:

I mix it with water 1:1 and spray it in the tb.  Then go out for a 20 minute ride and change the oil.

How do you get it to mix with water.. The stuff seems to separate for me.. Just like solvent and water..

mosquito abatement?
when running boat rentals I did all the 2 smokes every few months.
it really takes out the carbon.
run them, spray into carbs till stumbles/dies.
let sit.
fire up and take for a wot run. smoke out the lake, change plugs.

Keep the water out. There are good reasons not to allow water to get into the oil, and it will. Even temporarily is not good
The ingredients of Seafoam are petroleum distillates I suspect which is why they don't mix.

what Seafoam does NOT do is clean the crud off the backs of intake valves  :emsad:
Haven't found anything to do that yet, short of taking the heads apart and beadblasting or cleaning manually.

If you use the additive in the gas regularly it helps but once baked on you're right. It helps to keep the breathing stream out of the intake.

Yes water is polar and the SeaFoam is non-polar so they will not form a solute.  Let's just say the molecules co-habitate the spray bottle while they are being transferred into the tb.

Water in the oil has shown to cause issues with the new tensioners. Some dealers that start bikes to move them in and out in moist areas have had some issues and had to replace tensioners, I am told. If the oil is milky after the treatment personally I would not go there.

I've used SF regularly for many years (a few ounces in every 5th or 6th full tank of fuel) - Christmas of 2013 when we went through Gracie's engine from the bottom to the top..........my indy's preferred machine shop dude looked at the cylinders & such and commented he had never seen the innards of a TC engine look that clean with 120,000 on it - only had to bore 10 thousandths to get them sleeves clean as a whistle - so Gracie went from 95 to 98 (ya never have to be concerned with carbon if it never has a chance to build up!)

He didn't test that brand yet, if you watch the you-tube video,look at the vidwo selection along the side. He tests other brands like techron and gumb out...he didt say positive thing about them.

I have a weed wacker that I got for free when my girlfriend and I bought our house 2 years ago. Its a 10 year old or so Ryobi. It starts hard and needs to be run on half choke most of the time. Even then I cant get it to rev up. I poured seafoam in the gas while it was running about 30 seconds later it wound right up and was screaming. The stuff really seems to work. Atleast better that anything else ive used.

I used it in my '97 Dodge 360 when I had to repair/replace the warped intake plenum plate. Smoked out darn near a city block. Neighbors were NOT amused.

I have used seafoam to fix leaky intake valves due to carbon. Chevy "iron duke" in a cavalier. It would idle just fine, but as soon as you put a load on it, it would stumble and miss. After seafoam it ran just fine.
I have also had not so good luck. I had worked on a jeep 4.0 with a slight miss once in a while. I used seafoam to clean the engine cause I thought it was carbon buildup....turns out the carbon was making the cracked valve seal.. It ended up with a dead miss after that. Then I took the head off, the pistons and inteke track were the seafoam had touched was very clean. You could see were the seafoam touched and were it didn't.
Does it work yes. Sometimes to good.

  Since first being introduced to Sea Foam here 3-4 yrs ago I use nothing else. As a straight carb cleaner, I've found nothing that comes close.
I used it on a 4000watt Honda generator that had sit for 7 yrs full of stale gas. Buildup in the carb was almost 1/16" of a shellac looking material. An overnight soak removed 95%, everything except the tiny little idle mixture jet was clean. I soaked it for another 12hrs, reassembled and it ran on the second pull.
My 124 had a little carbon, two treatments thru the gas removed 80-90%, good enough for me.
Its my go fix for any gas problems, and I've cleaned sever carbon from removed pistons just y soaking, it dissolves the carbon almost immediately. fwiw  Buffalo

Can it be sprayed into the intake on a Twin cam engine?
I have read conflicting reports on this site, so has anyone
done it to there Twin cam engines?
Title: Re: Does Seafoam Actually Work? (with Proof)
Post by: Hossamania on March 09, 2015, 08:30:33 AM
No actual proof, just anecdotal evidence of using it for more than 35 years. I always treat the fuel I buy for my small engines right when I buy the gas. Sometimes it sits in the garage for several months. Haven't had a problem. It does clean out carbs very well. It was developed for marine use, sometimes that fuel will sit in a boat for a few years. My boat will only use half a tank for 2 or 3 years in a row. It fires up every spring on old fuel.
There is always something better, but I haven't found it.

I too believe in adding to the gas tank but 
How about spraying it into the throttle body
while engine is running.

I believe many here have done it. It is petroleum based, so it should not be a problem spraying directly into the throttle body. It is advertised as safe for fi systems, including sensors and injectors. It can even be used as a cleaner on the exterior and moving parts, probably better, or safer, than carb cleaner. They sell Seafoam Deep Creep, which is Seafoam in an aerosol.

Seafoam is mostly tolulene (also octane booster to a point)
It is water-insoluble.
Many of the other similar products have a similar active ingredient. Another examples GM Top cylinder Cleaner, Berryman /Chemtool (different active ingredient I believe)

I have sprayed it into the carb on a 88tc and tb on a 96tc. Both had sat a loooooooong time (deployed friends) neither had been prepped before storage, gas was bad and made a mess. Yes it smokes badly when sprayed into a running intake but it cleans wonderfully.

I have sprayed it in high mileage chrysler 4 cylinders and a thrashed late 80's 460 ford. EVERY time it made a world of difference.

Spray it in with a spray bottle and keep the motor running, kill some bugs, enjoy it.

Another video from the same guy. I like Sea Foam, it cleans motors well enough that when there was pinging from carbon build up, that the pinging went away after cleaning.

I use it often in the bike, at least a couple of tanks a month.. 5 oz.. and fill her.. I use the same ratio in my Explorer, not as frequently though. Maybe 4 or 5 times a year.. I also ad 1 oz per gallon to my cans for every thing else like mowers, chain saws along with Stabil   fuel stabilizer.. this gas is crap and needs all the help you can give it.. Proof... 90,000 mi of crap gas on my bike and it doesn't ping as long as I don't put junk Accel wires on it... The Explorer and my Cub Cadet tractor used to hunt for idle speed until I started using it.. What ever the simple ingredients may be they seem to have the recipe right..

I had the "old fashion moth ball" to the tank of gas, so the fuel burns cleaner. The racers in the 50's did that on the drag strip.
