I've been reading some info most this, agglomeration of people maxim information technology'south good to apply to clean upwards carbon, fuel injectors, creepo case, etc. You're basically supposed to put it in everything except the radiator.

I was wondering what the Garage idea about this stuff. I'm doing a tuneup on my Freecar Altima, and it has 171+ yard miles on information technology. Can Seafoam damage an engine, especially a high-mileage one?

• #2

Putting it in the crankcase isn't worth much unless you've gone manner too long wihtout oil changes. Running it through the vacuum lines to the intake does wonders for some motors. On my sometime Jeep, it smoothed out the idle beautifully.

Seafoam won't damaage your engine. Will requite yous a sweet smoke show though.

• #3

It'southward snake oil, for the most part. You can observe some anecdotal prove of it helping this problem or that problem, but that'south it.

I'd never cascade it in my crank case. I'll concede it'south possible it could make some divergence by using it in a carburetor or fuel arrangement, only I wouldn't put it in my gas tank, either.

Basically, for whatever they tell y'all it can be used for, it's either an outright snake oil merits and non necessary, or at that place are better products for the different areas of the machine.

• #4

I subscribe to the notion that things similar this are exaggerated, placebo, harmful, or a combination of the three.

There are rare circumstances where pour in additives are great, and I have experienced them outset hand although i was told otherwise. Both involved an oil handling that helped stop oil consumption on my '84 Cressida with worn valve seals, and a '92 Jeep that was leaking from the rear main seal.

Neither had much longevity proof, because I junked the Cressida a few yard miles after treatment, and sold the Jeep shortly after. Both worked in the immediate. I'm bold the Jeep is still going because that direct six engine has rightfully earned a reputation of existence indestructible. The Cressida had a good straight 6 equally well, but lacked the torque of the Jeep.

i've used it... skilful smoke show...

people merits that white smoke is carbon burning... i accept a feeling it might merely exist seafoam called-for.

Dealerships exercise similiar stuff with BG 44k and BG intake clean, either at the fuel rail or throttle trunk.

The stuff is out there. Plenty of information technology but who knows really what works on what. Not many independent places/people take washed before and afters.

I've seen iii-4 guys post upward about http://www.auto-rx.com/ on forums that i visit, pictures weren't as clean every bit the photos at that place but at that place was diffrences. Just look at it this manner, people who do this stuff accept full general know-how and well most likely their engines are cleaner then others.

I still call up all are serpent oil but i practise purchase them from time to time when they are on sale. Lucas mainly for the buy one get 1 free bottles.

It will clean the carbon off of pistons/valves if feed through a vacuum line but so and so volition h2o

back in ~06, I had a 93 Honda Accord and an 03 Pontiac Montana.

The accord was a beater with 175k, the Montana had ~40k.

I ran seafoam in the vacuum lines of both vehicles. The accord definitely benefited, smoother idle and acceleration. It as well had one hell of a smoke show.

The Montana had no noticeable difference, and besides didn't really put out much smoke.

I always wrote it off every bit a much more than efficient Catalytic Converter on the Pontiac....

Now the Pontiac has 105k miles. Thinking I might endeavour it again this weekend to come across how much smoke I get

I remember it's a large waste of money and would never put it in whatever vehicle I own.

• #nine

I dont trust additives in my vehicle. Knowing my luck my engine would blow up.

• #10

It's basically a solvent, so if something is gummed up or sticking, it will loosen it upwardly. The thing is, on mod engines, using modern oil, and that are in daily apply, that's really not a problem. If you've had a '64 Chevy sitting in a garage for 15 years, Seafoam might work wonders. On a '98 Honda with 200,000 miles, information technology'll make fume, but that'south well-nigh it. If you lot want to knock off carbon, do some full throttle runs, preferably up a long hill. You'll knock the carbon loose.

• #eleven

Does seafoam work, Yeah. will it work for you, Mayhap.

Its main function is getting the carbon out of an engine and it works great on 2 strokes and onetime 4 strokes that take been around for years or driveling. It needs to be put in the intake AND crankcase. In the Intake it volition clean up the combustion chambers and valves forth with the top piston ring. It NEEDS to go in the crankcase to clean off the oiling rings if you lot are having an oil consumption problem. Don't run it as well long in the crankcase, just long enough to warm the engine upwards to become it circulated, allow is sit for 1/2hour and then alter the oil immediately. Ive had great luck with using it on old 2 stroke outboards fir restoring compression and on lawnmower engines that used oil. Even my old Explorer saw a meaning drop in oil usage as it went from 1qt every 500 miles to 1qt every 1500 miles. That said, water mist in the intake will practise just every bit practiced on that end but seafoam does wonders in a crank case. NEVER employ the water method on a 2 stroke though, it will wipe the oil off the bearings.

I've seen 3-4 guys post up nearly http://www.auto-rx.com/ on forums that i visit, pictures weren't as clean as the photos there just there was diffrences. Only look at it this manner, people who do this stuff accept general know-how and well most likely their engines are cleaner then others.

I still call back all are snake oil but i practise purchase them from time to fourth dimension when they are on sale. Lucas mainly for the buy one get one free bottles.

I did an Car-Rx treatment on my 98 Passat when I first bought it (2004). The 1.8T in the Passat is known for oil sludging issues due to a small crank case (iii.8Qt with the OEM small filter) and an oil return line nigh ii.5" abroad from the turbo.

After the first 2k mile stage, I had my oil changed at a jiffy lube type place, and the guy commented on how much sludge was dripping out of the crank.

I changed it again at 3k like you're supposed to, and noticed some gunk but zippo crazy.

Mainly I did it for peace of mind, since I didn't accept many service records from the previous owner, and he likely wasn't using the recommended synthetic.

As for Seafoam, I've done it a few times to the aforementioned car, half a can in the tank the other half sucked in through a vacuum line. The car felt smoother, though it could accept been a placebo affect. The smoke show all the same, was worth it. I covered my entire block in a thick blanket of white fume.

• #13

I've used it several times in a couple vehicles. The first time I used it I did notice an comeback, afterward that I tin can't say as much. My saturn has been plagued with a surging dispatch since I bought it 120k miles ago and I've tried several remedies suggested by saturnfans.com nonetheless the problem persists. The first tin can of seafoam was the only remedy that actually did brand the problem go away for a few weeks.

I think it'south a big waste of money and would never put it in any vehicle I own.

$v.
yeah, real big waste matter of money.

I've considered using it on my 87 Caprice for a while now. Having never washed it before I am a niggling hesitant to but unplug a vacuum line and put it in through there. Information technology would probably work wonders though from what I've heard.

Information technology works well on older vehicles. I have used information technology on over 10 cars for friends and family and information technology does assistance, most told me they noticed a differnce and most of them had no idea i used it. Helped smooth out the idle and acceleration on my 88 CRX, couldnt believe the smoke that created.

I wouldnt bother on anything with nether 100,000 miles on it though you lot probably wont need it.

ive used it on lawnmowers, jetskis, cord trimmers, cars, trucks, etc. Never had a problem with it, but have noticed good results on mostly the 2 strokes with the hesitation going away, potent acceleration coming back, overall better idle, etc.

Its not serpent oil and actually does work.

I need some help plz .. my local avant-garde auto, suggested me try sea cream..I don't like using additives, I put it in my gas tank. I have 2001 Dodge M Caravan been having crude idle northward misfires, they said they use information technology in their auto and never had issues.. I have 17600 miles..So it didn't assist but it smoking and asked them why .....the automobile associate said don't know why... the thing is information technology comes n go on smoking depends on my van and weather condition . How long before it stops smoking? bcz it been a skilful 3-4 months it worrying me. I called sea cream they don't accept clue and said become with mechanic.....I just desire make sure my engine not mess upwards..I should've passed on it.. I trusting the staff..normally, I've only use fuel injectors or gas treatments that it.. I capeesh any help thank yous!

Seafoam client service is right, you demand to have your machine looked at by a mechanic. Your automobile should not be smoking later on iii-iv months. Something is definitely wrong.

I was seeking a means of eliminating the hesitation and RPM drop beneath the idle spec on my old Trooper. The symptom seemed indicative of a muddied EGR valve.

You can have the EGR valve off the auto, replacing the gasket when restoring it, and clean it with carb cleaner, (peradventure) Seafoam, or a specialized cleaner. Bardahl makes a product that supposedly cleans the EGR "in place" without removal, and other YouTube "How To" videos and forums suggested using Seafoam in exactly the same way every bit the Bardahl production. Wynn'due south makes a like product. I deferred the attempt, since the symptom was occasional and minor.

Instead, I started buying the pocket-size $5 bottles of Lucas Fuel-Injector cleaner to add with a fresh tank of gasoline. Of course, the manufacturer wants y'all to buy more than and utilise more, simply I followed their communication to add a bottle of the stuff to each successive tank of fuel, and connected to use it by the half-canteen.

Whether it was the EGR valve or the fuel injectors or something else, the symptoms disappeared. I'1000 looking forward to my next smog-examination in January to see if there's improvement in the HC and NOx ratings, since I've been using Premium gasoline with the Lucas for the final year. Some sources say that using Premium gas volition renew a catalytic converter -- which is supposed to keep HC and NOx emissions low.

That sucker sure runs well now, subsequently a twelvemonth of Premium plus Lucas.

I am still sparing and cautious well-nigh additives in general. I have a pocket-sized oil leak at the rear chief seal of the engine, and the Blue Devil production "Main Sealer" works. They insist the use of their product is permanent, and you shouldn't demand to add it once more with an oil change.

My transmission besides leaks a picayune from the main seal in the bell housing. We torqued the tranny-attachment bolts to factory spec, and the leak attenuated, merely didn't become away altogether. I tin can't lose enough Dexron to justify adding an unabridged 9 oz bottle of Blue Devil tranny sealer. I might find nearly a thimble-full of tranny fluid in the drop pan later a month's time. So I'chiliad not going to practice more with information technology for the time beingness.

I feel like its a holdover from carburated cars or early on EFI. I don't feel like it has much place in a mod engine. I'd be more than worried about damaging a seal etc with it than whatever expert it would mayhap do.

I feel like its a holdover from carburated cars or early EFI. I don't feel similar information technology has much place in a modern engine. I'd be more worried most dissentious a seal etc with it than any good information technology would possibly do.

Like I said, I've been cautious. Blueish Devil products have decent ratings amidst customer reviews, but here and there you'll detect cases where the user overfilled the tranny, or the seals were swollen and so badly that the tranny started leaking like a sieve -- reverse the intended issue.

The engine Main Sealer and a similar conception -- both Blueish Devil products -- seem to perform more than reliably. I personally adjure to it. But I avoid products which remove "varnish" from the engine. It could be asking for problem.

The Trooper and its engine are 188,000 miles and 25 years former. I'll go iii,000 miles, and never accept to pinnacle up the oil. At 1 point, I'd go three,000 miles and the oil would be a half quart (of five) depression -- but this was apparently due to the leaky rear primary seal. For the additives mentioned here, I've never used the full bottle.

I figure if you accept a 25 year old vehicle with smog test results better than it had at 6 years former, it's probably worth it to alter the oil every 2,500 miles fifty-fifty if using Total Constructed. Baby that Sucker, I say! If an engine is going bad, "getting tired", etc. -- you would notice things gradually, like worsening smog-tests, burning oil, compression tests falling short. If none of that is happening at 188,000 miles, getting to 230,000 or beyond seems like a good bet.

I even so wonder about my head gaskets. In 2009, the water pump froze, timing belt broke, radiator was damaged. Nosotros idea there might exist damage to the engine, but "Nope." I was told that if impairment was done to the head gaskets, information technology might show in a month's fourth dimension, but "Nope." That was at least 30,000 miles ago. So like I said, it seems like a proficient bet for keeping the Trooper, paying for the peripherals and maintenance, and saving my money.

I might "endeavour" additives, as I have with the Main Sealer or fuel-injector cleaner. The Lucas cleaner is harmless. Only otherwise, why screw upwards a skilful affair?

Information technology can help clean the intake out merely at the same time y'all should never add it before a MAF sensor as information technology can cause it to go fouled.

It has no purpose in fuel compared to meliorate treatments similar Techron or similar. It has no purpose in oil, even if you are a believer in doing oil flushes (there are passionate arguments on both sides for and against it) compared to a purpose specific production or just using diesel fuel. Generally, yous're better off simply changing oil more oftentimes with a full synthetic and letting that gradually clean out sludge.

Keep in heed that the white fume coming out the exhaust if put in the intake or fuel, inevitably causes deposits on your true cat and o2 sensors. Any goop it cleans out upstream may also deposit there. Information technology should be used minimally if at all as preventative maintenance, instead is more than of a concluding ditch cleaning effort earlier replacing parts.
