Do you get it dyno tested before and after using? Do you open up the engine and see what good it has done?

How so?

The success rate on two stroke outboards has been known for decades.

The bigger question is if the stuff works on modern four stokes as well.

I use it on my mower and snowblower and both run much better on it especially since they sit for long periods of time without being used.

It has been a life savor on my snowblower.

No dyno test, but I've seen the compression increase after decarbing a motor.

Gas with ethanol has wreaked havok on my small engine stuff. Just paid a $50 repair bill on my stihl weedeater because of ethanol. Awhile back my Suzuki ozark would start but not run long and it smoked bad. I got it to run long enough to get some sea foam through it and was finally able to ride it again. I personally believe the cleaning agents in the sea foam helped clean out the carb. So in that case I believe it worked. I will not buy any more gas with ethanol for my small engine equipment.

The O rings, gaskets, fuel system, and seals of most small engine stuff doesn't get along with alcohol.

Try 85%. When e85 started showing up like 20 years ago, I did a stream of fuel supply repairs; eventually bought nitrile lined hose by the roll. Nowadays, I don't really trust fuel vendors (or much less anyone lol) and stabil stored fuel, and installed in line shut off valves on all the small stuff; close and run till carb bowl is dry.

Now, I saw this video where a guy had 2 of the exact same year make and model trucks.
One truck he ran regular unleaded through.
The other truck, he ran straight corn gas through.th
Neither truck was a flex fuel vehicle.
The truck that ran the straight gas, was carboned, gunked and cruddy.
the truck that ran the corn gas, All the parts looked new.
Each truck had 200,000 miles on them.
I wish I could find the video for all the non believers.
I was shocked.
I say, "Give me a gasoline without any additives"
"Give me a fuel for my vehicle that doesn't cost 4.00/Gal." or more...

I use Seafoam in everything: cars, motorcycles, lawnmowers, trimmers, blowers. I swear by it.

Well I use seafoam in my motorcycle and I do see that the engine idling smoothens out.

From all the above discussions looks like the tj will take it. Lets see how it goes.

I forgot to mention, I have poured a can of sea foam in my gas tank too. didn't harm anything, actually cleaned out the intake a bit. some smoke blew out the back and all was fine. Didn't trip any codes, I am going to take a can and suck some right into the intake manifold via a vacuum line next.
I did that with my volvo. <make sure you do it in an area that nobody will complain about the smoke> My volvo smoked so much it was embarrasing!

I had a tick my engine before, put some seafoam in the crank, then changed the oil and put some in my gas tank

no more ticks

So you are supposed to change the oil after putting it in the crankcase? Ive gathered that from seeing where others have chamged it immediately

Seafoam is considerably thinner than motor oil. if you add it to the crank case, don't exceed the amount recommended on the bottle (1/3 can IIRC). Try to avoid high RPM driving and change the oil about 50-100 miles afterwards. This will decrease the chances of damage from too thin an oil viscosity. I've read of a couple of folks who spun bearings on another auto forum I belong to. The common denominator was they both had Seafoam in the cranks, had both exceeded the recommended amounts in the CC, and had driven for hundreds of miles. In fact, one actually had his car on a dyno when it threw a CEL and started running like poo.

I also bought an old cbr 600 one time that would not run good. It stumbled on take off and would not rev quickly like it should. I am sure it sat and the gas turned bad in it. Anyhow I mixed some seafoam with the gas and ran a tank through it. Sure enough it smoothed out the carb problems. I will add I do not think the seafoam would have helped if the carbs were to clogged up. Once it gets so bad the only thing to do is take them apart and clean them.

change after 50 to 100 miles of driving.

Yes. After a few hundred miles I believe

I haven't used Seafoam myself, but reading the stories about pulling it into the intake manifold / carbs / fuel injectors, and the subsequent amount of smoke produced upon startup sure sounded familiar.

For quite a few years I owned a first gen RX-7. With the rotary engine it was quite common for there to be gum and buildup in the apex seals, which then wouldn't seal against the rotor housing, causing poor compression and therefore rough running.

For those of you not familiar with rotary engines, the apex seal basically performs the same function as piston rings.

A VERY common fix for this was to put no more than a capful (if even that much) of ATF into each barrel of the 4 Barrel Nikki carb. Then disconnect the ignition coil, and turn it over to coat the rotors (and therefore the seals) good with the ATF.

Let that sit 24-48 hours. Then, alert the neighbors (unless you want the FD at your place), fire her up, then proceed to get completely enveloped in a sea of white smoke.

Once done I could definitely tell a difference in power and smoothness.

While I'm not attempting to turn this into a thread on rotaries, I guess my point is that if ATF is such a common fix for gum and varnish, it may be possible that Seafoam is a glorified solution that the ATF can handle just fine and much more cheaply.

I really have no idea for sure, but just thought I'd share from my perspective as a former rotary engine owner.

I have used Sea foam (not the liquid, the actual foam spray) in the past in my ZX9R that sat for a year when I hurt my back and had surgery. It cleaned everything out nice and the bike ran great.

I have some friends who are not well educated with taking care of their lawn mowers / weed eaters and let them sit for long periods of time with old gas. I have used Sea foam to fill the carbs and in the cylinder. Let them sit for a couple of hours and then they fire right up. Then the discussion about stabil and why they need to use it so they dont have to bring me their non running mowers and such.

I dont pour it in my gas tank or crank case. I have helped my dad back in the day use kerosine If there is too much sludge in the engine from lack of oil changes. These were older vehicles decades ago. The amount of sludge that would come out when we drained the oil was crazy after doing this. It never caused problems if done right.

I use it in my car and my motorcycle and its great.

Thanks in advance.
If the fuel delivery, supply, and base engine are in good condition not much is likely to change. SeaFoam, Berryman B12, Casite, acetone/xylene, nail polish remover, are solvents.

It used to be known as the "million dollar miracle" because it was priced higher than Casite. GM Top Engine cleaner is another similar product, and was used for many years to correct "depressed vacuum syndrome" on early speed density fuel injected engines.

I forgot to mention it emulsifies water in fuel. This is not necessarily a good thing, especially in a diesel. Even on small engines that have varnished, there is no substitute for draining the bad fuel out of the tank, lines, carb. Replace filters and rebuild carb or replace other fuel system components if they won't clean up.

I've used solvents as an intake enema to correct depressed vacuum. But the last time that was on a 91 Caprice 305 the old lady never got above 45. It was a coked-up mess.

Ive used it in 3 different vehicles now. Works great to me. My Jeep was running sluggish when I got it. I ran a can through the tank and 1/3 in the oil, another 1/3 through the vacuums lines and then drove the piss out of it for a half hour. No problems since then.

YES!

As others have said, it's about bad gas. If you're driving back and forth to the mall, you can save some money by not buying shitty gas in the first place. If you're running around out in the boondocks, seafoam is the stuff to have. I carry 3 or 4 cans as part of my toolkit, and use it anytime the Jeep decides it would like to idle rough/slow/fast/otherwise wonky.

(This guy actually sold me great gas, but I was glad to have my seafoam along anyway!)

SeaFoam De-coded

Hey bud,

I do this for a living. For almost forty years now. I work for an oil company that manufactures high end synthetics. In answer to your question, yes it's a good product. It's been around since the late 1940's. It was primarily used in marine applications hence the name. As I'm sure you're aware there's about a million of these fuel system additives on the market. Some work better than others. Price doesn't seem to be indicative of quality or performance.
As far as why it works I'll try to explain.
There are three basic ingredients in the stuff, IPA, Naptha, and Pale Oil.
The IPA distils at about 200-250 degrees, the Naptha at around 400, and the Pale Oil at about 800. For some reason, in combination, it distils at about 850 degrees.
It is an all petroleum based product with no added detergents therefore no added deposits from burned detergent.
It also has a "sheening" affect, meaning that it stays in suspension and on the cylinder walls and other engine components aiding in lubrication and constant prevention of any varnish build up from high temperatures and pressures, and fuel combustion. All gasoline brands despite their advertising leave a varnish behind as a result of combustion. The pale oil acts as a petroleum solvent to keep it constantly clean and lubricated.
The vast majority of similar products do little or nothing in comparison.
This is an old but very good product. It works well, it won't harm anything, it can be used as often as you like with no deleterious effects on the engine or the oil in the crank case.
I've run synthetic oil for as much as 25,000 miles between changes while using Seafoam in almost every tank fill up over the course of two years and had the oil analyzed upon draining. There were no unusual signs of oil deterioration.

I hope this helps to explain what's going on with this stuff.
Feel free to email me at vonulm@msn.com if you have any further questions.
Tim

I'm a fan of Seafoam, but there's no way in hell I'd run a 25,000 mile OCI. The best I've gotten in my cars was about 8,500 miles before the guys at Blackstone Labs were telling me to stop trying to extend the OCI. Also you'd have to wonder if the filter was doing any good or just in bypass mode at that many miles.

I haven't used it in my Jeep, but I had a chainsaw that would heat up and vapor lock. Adding a couple cap fulls of sea foam to the gas tank seemed to make a difference and it doesn't vapor lock.

[QUOTE=Jerry Bransford;
If you have a lawn more or similar engine where the gasoline regularly turns to varnish from sitting too long, use a more suitable product like Gumout or Sta-bil to clean things up.... they were specifically designed for such problems and cost 1/3 as much as Seafoam.[/QUOTE]

Don't agree that Sta-bil works at all & definitely not great like Seafoam does in small engines.

I live in a Ski Resort on over an acre. I have 3 generators, log splitter, push weed wacker, hand held weed wacker, lawn mower, snow blower, 2 chain saws. ---- I keep 20 gallons of fuel on hand and put in lots of Seafoam before filling the 4 containers at the gas pump. Since I started using Seafoam I have had NO repair bills for clogged fuel systems & carbs after fuel has set for long periods in all these tools. --- When I used Stabil years ago the exact same way, I could count on having $300 worth of repair work each year at the chain saw/small engine shop cleaning out various fuel system components.--- SEAFOAM Rocks, I love it.

I have had the exact same experience with Sea Foam at my Northern cabin. Golf carts, chain saw, weed wacker, outboard, carburated 89 YJ, log splitter, all have been terrific since winter treatments with Sea Foam. Much better that Stabil.
