I was thinking about putting some C-FOAM in my car but i was not sure if it was recommended. I have heard a lot of really good things about it cleaning all kinds of crap and black stuff out. It is suppose to really clean it out I have had several people tell me I should try it but I was not sure maybe someone will opine and let me know.

Re: Low Compression cyl 3- Bad Valves- Try TEC?

DO NOT dump snake oil in the engine or fuel tank. You would not be the first to come back with problems afterward. Everything you've heard is marketing hype from the manufacturer to get you to spend your money. You wouldn't expect them to say anything else, would you?

:hijacked: I started a new thread for you.

Your 1997 Northstar ??? Or the Expedition........for starters, take a good look with a strong flashlight down into the chaincase - the oil fill cap hole. Is there any "gunk" or "sludge" down in there that would make you want to pour solvents into your engine oil ?

Remember that gasolines and especially E10 are powerful solvents - yes, the PCV system in either engine will deposit oil vapor residue in the intake manifold BUT - fuel is injected downstream of that manifold, so fuel solvents don't work there, either. Black gunk and crap ?? Ummm......burning a mix of distilled petroleum solvents in addition to gasoline will add to the "gunk", not remove it.

Read Ranger's post again: 99.99% of fuel and oil additives are made for one reason and one reason only: We all want desperately to "make it better" - and the snake oil salesmen make billions on that desire. P.T. Barnum had the right advice.................and he made millions in its application.

Yes, you can use specific chemicals to clean engines - most of the time they aren't needed, and you don't burn them: they're installed, the cylinders soak, and you then vacuum out the stuff.

 

[N*Caddy]

Just don't put that crap into your engine!

 

[zek4964]

That is why it is better to ask first not later...Thanks for the advice and I will not be using it. The name of it just sounds harsh in the first place that's why I was skeptical. Glad I asked.

I have been using Seafoam for many years. Admittedly I do not put it in my oil. I run it through the Schrader valve when I clean injectors. You will find nothing better to clean injectors. You have to use a pressurized injection cleaner to do this and mostly only shops have these. I built my own and it works just like the one the shops use. If you put anything in your oil, use Motorkote. It is not a snake oil. This stuff is for real and I have been using it since 1997. I had a 3.1 Lumina that has been sold and resold so many times that it has its own pedigree (lol). Last count was near 300,000 miles and no failures. You will hear many tell you to stay away from additives and I would agree, Motorkote is not an additive, it absorbs into the metal. I did my own test in a drill press with over 200 pounds of force with metal on metal and I could not stall out the drill press. I put this in all of my engines including mowers and I have never had a failure due to components wearing out. My 2005 Durango gets 22mpg. This stuff really works.

Motorkote is not an additive, it absorbs into the metal.

Sounds a lot like Slick 50's claims for which Andy Granatelli was slapped with the largest law suit in US history by the FTC if memory serves me correctly. Metal does not absorb liquid. That is pure marketing hype.

My '02 SLS is using about 1 quart of oil every 800 miles or so. Plus I have carbon built up in my cylinders. I do not get enough opportunity to do wide open throttles so I need another solution. I went to my local dealer to get the top engine cleaner to do a piston ring soak. They told me that GM doesn't market it any longer. One of the mechanics told me to use Seafoam. I asked him what their procedure is for this if GM doesn't use the TEC anymore. He told me that they replace the pistons and rings. Screw that. So I will be using the Seafoam for the soak but not putting it into the oil or gas tank. I also bought a bottle of Lucas upper cylinder lubricant that I am going to run in the gas for in case my injectors need any cleaning. Considering the car has 123,xxx miles and no engine cleaning at all has ever been done I guess it couldn't hurt

gm replaced the top engine cleaner fluid with another fluid that is a concentrated green liquid that you pour into the cylinders (as sub mentioned above) then vacuum out

it is not supposed to be sold over the counter so that is why you were told there was no replacement ... they could have tried to sell you the service though
(that dealer might not be the most 'clued in' though)

 

[Ranger]

Dadillac, if you are going to use Seafoam, I think it might work well if you use the same procedure as you would using Techron. That is, pour it in the cylinders and let it soak as opposed to sucking it in through the intake and burning it until the engine stalls and the plugs get fouled.

That is my plan. Pour it in through the spark plug holes and let it soak for about two and a half hours and then vacuum the liquid out. I am installing new plugs and plug boots. An oil change will follow after running the car for a long drive.

+1 on top cylinder proceedure. Too harsh for the crankcase.

 

[Submariner409]

TECHRON is marketed as a fuel system cleaner, to be added to gasoline at a concentration of 20 oz. to about 20 gallons of gasoline. Frequency should not be any less than 3,000 miles between uses.

However, I also use it, mixed with gasoline, to clean small parts of grease and grime. It works - but it's expensive. I think the 20 oz, bottle is up to about $15 retail now.

Just bought a case of 12 on a special from Auto Barn (coupon SPRINGTEN) for $8.43 a bottle, shipping included.

"Upper cylinder lubricant" is just that: Light oil, blended into gasoline, with the theory that some of it will condense on the upper cylinder walls and inner valve stems, thus lubricating them. Same principle, but lesser concentration, as blending 2-cycle oils into gasoline. It is not designed as a "fuel system cleaner". Think Marvel Mystery Oil. ANY gearhead worth their salt has a quart on the shop shelf..............

 

[stsevillests]

I used Seafoam in the gas tank of my last car to clean fuel injectors a couple of times and never had any problems with it. Also I ran it in my riding mower and a little bit in my 2 stroke weed eater and seen major improvements there. I didn't put it in the motor oil, just in the gas. I know a couple guys with boats here in Florida that swear by it. I wouldn't mix it in my oil or suck it up through the brake booster like some of them guys do and smoke up the neighborhood (check out youtube LOL)

I have been trying Marvel Mystery Oil lately after reading a lot about it online. At first I just added it to the gas tank per bottle instructions 4 oz. for 10 gallons of gas. The Seville ran a little rough and I thought I messed up by putting it in there. The next time I drove it, it ran really good! Real smooth like floating down the road! A big difference. Last oil change I was skeptical about substituting a quart of Castrol High Mileage Oil for a quart of MMO but I did anyway. I know todays oils have all the cleaning agents an engine needs but I don't think it will hurt anything.

I changed my mothers oil in her explorer and put it in her gas and oil. Next day she asked "what did you do to my car?" I asked why? She said it is really running good! I may sound like a commercial for Marvel but I can tell you it is doing something, it can't be just in my head if my mother that just gets in the car and goes noticed a difference.

Also I had a little oil leak, few drops of oil on the ground. It has stopped leaking but that could be the seal conditioners in the high mileage oil. I thought that was all marketing too but after the third oil change with Castrol high mileage it has stopped leaking.

 

[wljlds2]

False my friend, metal does absorb. I have been a quality tech for near 27 years and have worked in many labs. The right fluid can penatrate into the pours of metal.

 

[RippyPartsDept]

doesn't that depend on the metal though?

 

[wljlds2]

Any metal that is cast or forged is porous. The least porous is billet materials but even that has pores. Let’s face it, engine blocks and moving parts are made on the cheap, otherwise everything would be from billet. You can place any metal in your hand and it will expand regardless of how microscopic, it will expand and it is all due to the material being porous.

 

[Sevillian273]

it is all due to the material being porous.

Dont you mean thermal expansion which occurs on a molecular level in all materials, solid, liquid, and gas? How does the porosity of a material cause it to expand?

By the way, Seafoam works on combustion chamber deposits. It was a last ditch effort to cure an incessant spark-knock that I had and it undoubtedly took care of it. As for the rest of the claims on the can, I cant confirm.

 

[ThumperPup]

i used to use seafoam in my Lincolns all the time
won't put it in anything els eveyr other car i put it in it runs ruff and just plain old fouled up
don't put that crud in your car

Where have you been Pup? We haven't heard from you in a while.
