Seafoam sucks

I used a can of Seafoam on my 01 v6 and nothing happened. No smoke, just a little water from my tailpipe. Also it murdered my gas mileage. Driving 60mph i could watch the needle move like I was driving 115mph. Any ideas why it didn't work and why my mileage dropped?

I haven't run it through the intake yet, but I've never heard it causing bad gas mileage. Try going to their website and make sure your doing it right. Keep in mind, it cant fix probs of parts that aren't functioning mechanically. Like if your IAC or EGR has failed.

Prob put it in the gas... I still don't like sea foam on the basis that it can knock big deposits into bad places.

Yeah, supposedly it will "burn up" those deposits. All of them...?

Yeah... I've seen 2 engines clog up an oil pathway and burn a cylinder. Also saw a s2000 come to an abrupt end 10 seconds into the process.

Re: Seafoam sucks

I did it the way the company says to do it. They have a video on YouTube. I put 1/3 in oil, 1/3 in gas, and 1/3 into the brake booster/intake line. I let it run for 5 minutes then let it set for 5-10. Then restarted it. When I restarted it fluid slowly dripped from the exhuast. the more i revved it, the more fluid came out. I drove it around town but still no smoke. My gas mileage has dropped by 1/2. I plan to change the oil this weekend to see how it looks.

Re: Seafoam sucks

well 2 things..

1. the way you ran it might be how the company tells you too but it is in no way the best way to run it (talking about the run for 5 mins then let it sit for 10)

2. i have always and will always run this stuff because i've only had good experiences with it

also keep in mind not every car will smoke after seafoam. this would happen alot when i use to work in a shop that did injection cleaning services...we had a drip machine that would pour cleaner into the vac line for 20 minutes on average to empty a bottle. 75% of the cars smoked

last question is how much gas did you have when you put it in there? when did you last purchase gas? maybe you picked up crap gas in the process...that sounds more likely for the mileage issue then the seafoam

Yeah I have ran it in all my cars several times and ran some thru my R6 and all benefited. And if you're worried about it breaking off "build up" and it getting into your engine, then you have bigger problems. Like, how'd this crap get past my air filter? If you have a good air filter then the only build up should be oil, which burns like it always has in your stang, unless you have bypassed your PCV's. I just stuck the brake booster hose in the bottle and just lett the motor "sip" it. No probs.

Re: Seafoam sucks

I had 1/2 a tank of gas from Wal-Mart(that's all I ever use) I bought that day.My gas mileage still sucked today. I put fresh gas in and goin 40mph you can watch the needle drop quickly. I've never had this problem in any vehicle. My 84 silverado with a 350 got better mileage than I am right now. Gonna take it to a shop and see what they say. I can't afford bad mileage.

Re: Seafoam sucks

no leaks in my fuel system. combed everly inch of it. and i know wal-marts gas sucks but i can barely afford it so why try to buy more expensive gas? Ive had 1 bad tank of gas from them and i was reimbursed for the repairs. this tank was good. it only started acting up after i used seafoam.

Re: Seafoam sucks

Well they said that the 'bad gas' is rare. But if they are willing to pay for the repairs then it's cool. I just make sure I keep my receipts just in case. I love my car but the problem isn't gas, its the seafoam. I'm calling the company when they open to see if the can help. I gotta take it to a shop and gonna see if they'll cover any work done. The motor runs rough and tries to stall in idle. The motor is choking and I Don't have time to get under the hood to see where the problem is. Got a new fuel filter, air filter, spark plugs, wires, ignition coil, and was running smooth before I used seafoam.

Check your plugs again. If you used the deadpan and didn't let it sip slowly then you may have fouled out your plugs. If they have a reddish burn coloring around the electrode replace them

Re: Seafoam sucks

the cost difference between bad gas and premium even isn't that much per tank.

Re: Seafoam sucks

Sorry to say, but you should've searched before using sea foam. Its just another gimic that does more harm than good.
You probably got your O2 sensors warm, then allowed the motor to gulp down said liquid hurt, ruining your sensors and possibly cats.
Or it could've washed sediment into your injectors (from your fuel filter) causing injector(s) to stick open.

Why, why, WHY do people keep suggesting these dumb products???

Let me set the scene for you....

Years and years of driving your engine with a working PCV system. The PCV system is throwing oily vapor down your intake manifold, which it clings to the sides. Your air filter does not catch all debris, thus letting said debris cling to your intake manifold runners. Over time and heat, these particles build up and harden to carbon-like deposits. Left there, they pose no hazards to your engine except for the performance loss of reduced air flow.

Now take all those deposits, and wash them into your engine's combustion chamber.

Your rings and pistons take a nice dosage of sediment.

You have just taken life off of your engine. For what? A 'cleaning'? A cleaning that should've involved taking off the upper intake manifold?

I have no idea why people use the intake foam. Its awful.

Re: Seafoam sucks

again mike as we have said in your seafoam thread that is your opinion...you assume sediment that gets washed will remain there...however that cleaning product that you hate so much will clean and help burn it away throughout the engine. if you and the OP wish to never use seafoam again that's perfectly fine, however the other 99% of us will.

Now user error is possible here..however it's doubtful we will ever know for sure

Re: Seafoam sucks

That wasn't "my thread", i just posted in it.

Please, please, please
tell me how FACT is my OPINION.

Washing crystallized particulate into your combustion chamber is inherently BAD for your valves, cylinder walls, rings, O2 sensors, and cats.
This is not OPINION. This is FACT. Please, just understand that.
An opinion would be "that color green SUCKS".
A fact would be "this process has been proven to cause damage".

Doing the intake manifold clean can wash huge chunks of carbon buildup off of intake valves, into the combustion chamber. There it can bang around until its turned to grit (washing down your cylinder walls, scoring the rings), or can get crushed by exhaust valves (damaging valve seats) then thrown into your catalytic grid.

Doing the fuel tank clean WITHOUT changing filter first, can wash all fuel filter particles into your injection system, then regulator, then back into your tank, for the process to repeat.

BigT03 is just another statistic of using a product that others recommend.

I myself have NEVER used sea foam or any other product like it, and my vehicles have all run flawlessly.

Then why run an air filter at all?? Incoming debris will just flow in one end and out the other right?
Now mix that incoming carbon with a liquid of your choice and see how long it stays in the combustion chamber, or how many scratches you get in your cylinder walls.

Sorry if I seem passionate about this subject.
I can usually sit back and laugh as someone destroys their engine. When the same is done because someone unknowingly got bad information off the internet, I feel bad. (damn these feelings!!!)
I can sit quietly if someone says engine restorer, Prolong, slick50, etc is the awesomes!!! Its not going to break anything by using it. But when some of these (harmful) BS products get pushed on the unknowing, isn't it our duty to step in and stop it?

If it hasn't been said already, change the oil. I promise your gas will instantly get better afterwards. I ran mine thru last year, 1 can in gas, 1/2 thru intake, 1/2 into crank case, the oil will become horribly thick afterwards, and will need to be changed within about 50 miles of running it. If your engine didn't smoke, it may not have been too bad. Mine smoked like a freight train the first time, but it hasn't really anytime since. If just using it in the gas and thru the intake, then the oil will not need changing. However, i would recommend next time taking it to a local AAA if you have one. 100 bucks for fuel system cleaning and it does a damn fine job. I removed my valve covers shortly after and could eat off of them, and my intake was clean as well. BG 44k is what they use and is hands down the best product on the market for this stuff

See with filters in place I don't see how any "sediment" gets into a motor. If your fuel filter is good and your air filter is good then nothing should be getting in there, but gas and air. If your gas doesn't "knock" any "crap" loose itself, in the fuel system, then I doubt an additive would. And if you run the stuff thru your intake and "break sediment loose" then you need a better air filter, seriously! if everything is in good working order then the stuff can't "harm" anything. The product says to get your motor(including, exhaust system, fuel system, oil) warmed up so when you run it thru it WON'T damage anything.

Re: Seafoam sucks

Ok, you're right.
Im sorry.

BigT03, you must've done something wrong when you did it.
You probably should've rev'd your engine when doing the intake cleaning.
I highly doubt the sea foam caused the damage you're describing.
These guys know what they're talking about.

actually revving isn't a good idea. when connected to a fuel treatment drop bottle you want to let it idle for the full 20-30 minutes it takes to slow drip a bottle. going faster then that you can foul out a plug, but again you said it yourself you've never used any of these products. the seafoam could of indeed caused his issues...however it may have been due to user error not the product itself. and thanks for that last part...a compliment here and there can really make our members day

Cats. If your running seafoam through the intake and have catalytic converters the deposits exited out of the engine can completely clog your cats. Personally I'd have your cats checked..

Re: Seafoam sucks

also running crappy fuel that doesn't burn right can cause cats to clog and upstream o2's to go faulty...just to add to the idea bank

Simple solution, gut the cats and the drip method is really the only safe way to pull it thru the intake. When that stuff burns, it burns red hot, ive actually seen people try to do it themselves, and you go to look under their car and the exhaust system is just red from the heat. Good way to ruin your cats/sensors. People sell the actual gravity drips to do it properly on ebay, bout 100 for a good one if i remember correctly. Same thing for the bg 44k, but alot cheaper
