Because they want to make money.

Ford Motor Company will naturally say "no additives."

Companies who make and sell these additives, like Seafoam, BG, Wynns, Motorvac, etc. will say their product is good to go. He said/she said, and all.

Ultimately, Ford says no additives to protect their personal interests (to keep from having to buy an engine or something in the instance that any of these systems or chemicals cause damage), the companies who make these additives say to use them to protect their personal interests (making money), and the folks at the dealership will tell you to use these chemicals to protect their personal interests (making money).

I don't like or believe in Seafoam because of what's in it. I haven't seen any personal, first hand instances of damage or destruction from it; likewise, I haven't jumped off any buildings, wrestled any alligators or brought a knife to a gun fight to know that those would all be bad ideas.

Looking at what is in Seafoam, I fail to see how any of the ingredients will do what they say it does, but I can see how it would cause other problems, like hot spots from the naphtha burning in the combustion chamber, or damage to O2 sensors and/or catalysts.

 

I have used seafoam on my boat and it made my boat run faster and cleaner just smoked up my street but was well worth it! Need to try it on my 06 with 51,600 miles before I change my plugs.

 

The thing is we have not seen proof either way.

I seem to recall someone somewhere who was dropping pieces of carbon into different fluids to see if there was any indication that they did as they claimed. I would like to find that. I don't think carbon will dissolve in Seafoam, but it will soften.

If spark plugs come out easier with soft carbon on the bottom of the plug, then we got something.

 

I'll have to agree. No matter what you've read from manufacturer's claims that they can reduce or eliminate carbon build up in your engine, it's wrong. carbon is insoluble. it's akin to trying to disolve a diamond, just not as pure.

so what are the makers of seafoam doing by using naphtha and pale oil in their product? well the naphtha may well be an attempt to remove the carbon, since the only thing that seems to get rid of carbon is heat (carbon dissolves in molten iron). Naphtha burns very hot but it's not quite up to the job. then the pale oil, which as i'm sure anyone knows, smokes like crazy when you burn it.

so you pour the stuff in, the naphtha tries to clean what it can't and the pale oil burns until it comes snorting out your tailpipe. your neighbors got a show and you wasted $5.

 

So what you and Quinten are saying is that since carbon is this ultra hard diamond like substance, all the fuel injector cleaners on the market, both consumer grade and done by professionals, are just one big ripoff? And those of us who have had results from said products are all just nutjobs?

Yeah, whatever.

 

pretty much.

carbon is one of the most stable elements on earth. you would need something that chemically reacts with carbon to dissolve it, of which, a fossil fuel based detergent isn't going to do anything. you can believe what you want, but you can't argue with science.

 

Explain it to me otherwise.

You see what's in Seafoam; explain to me how it does what they say it does with the ingredients in it.

 

but...but...but...

everyone says it works! look at the smoke! it has to be doing something!

why would a professional shop charge me lots of money to run the treatment if it did nothing?

 

I dont need to explain it, to you, to me or anyone else. I dont care how or why it works. It worked for me. Truck ran better, idled smoother and got better gas mileage. Why over analyze it?

This isnt like the "cold air" intake threads where people claim the truck is faster and they can "feel" the extra horsepower. The numbers are there to prove it on this one.

It all comes down to preference. I have used it with good results, so I will continue to do so.

 

At one time that was true. For most products on the market that is still true today. I don't think Seafoam dissolves carbon, or claims to dissolve carbon.

 

So, I explained my reasoning as you requested, logically, by what Seafoam really is, and you're more or less saying I'm a stupee-head and you're taking your ball and your towel home with you.

ETA - You're not even worth the effort. Nevermind.

 

hehehehe......

ya gotta love these threads....lots of time for me......

I let the vacuum hose suck up 1/2 a bottle SEAFOAM and poured the remaining 1/2 in the tank in my 2004 5.4 with 100,000, let it sit for 15 minutes, went for a "screamin eagle" ride (Harley term! ) and got minimal smoke out the pipe, but what it did do was smooth my idle big-time and I think it slightly improved my mpg.

Did the same to my NISSAN Pathfinder, tons of SMOKE and much smoother engine performance.

Just a personal observation for all of you......
I will be doing it again in 6,000 miles!

 

so you're saying there's products out there that will dissolve carbon? i'd LOVE to see this list.

 

I always heard that seafoam fouled spark plugs easily and was best used just before you replaced them.

 

i was under the same impression and that what i did to my trusty crown vic first time she was ever seafoamed she was sitting at 310,000 miles and i did the seafoam treatment on it and it really helped the car. I did it then two days later changed the plugs in it and she runs like a brand new one now. I think the stuff works great. I just did it to my f150 and it is running alot smoother and has better throttle response.
