"Truth" about seafoam from technical director, Jim Davis


On fuel injection if it goes through the fuel system it does not go through the upper intake. I know the guys at an auto electric place and they did everything to get the check engine light to go out on a vehicle then they sprayed out the intake with cleaner and it shut the light out. Whatever was the problem it didn't show up on the scanner. Yes vehicles can go 300,000 with regular maintenance......if you start when they are new. Most don't get anything but an oil change and that usally long overdue. And that describes most of the cars and trucks I get cause I usally can't afford anything else.

The real truth

Seafoam is not all petroleum since it contains isopropyl alcohol.

Seafoam will do nothing through the gas tank. There are only two chemistries that clean through the gas:PIB and PEA. These are found in STP, Gumout, Techron, Prestone.

The white cloud coming out the tail pipe is a combination of the mineral oil and unburnt hydrocarbons since the Seafoam flooded the intake. This is bad for the catalytic converter and the environment.

Added to the crankcase, Seafoam does thin the oil so don't drive with it in the oil. Thinning the oil is a good way to get out some extra sludge at an oil change. A less expensive way to thin the oil is to use kerosine. Add to the oil and let it idle for 5-10 minutes then drain. Thinning the oil lowers the protection, so don't rev the engine or drive the car.

Adding products like Seafoam and Lucas Upper cylinder to your gasoline treating a 4 stroke engine like a 2 stroke. You are adding oil to your gas. As we all know, burning oil make the engine dirty, not clean.
 
WOW, for your first post. You revive a 4 month old tech article. And then dazzle us with your extensive knowledge on a product that has been proven to work in all the ways you say it doesnt. Not to mention the post being written by a fellow who made this product his life. So I guess all his knowledge is a waste? Thanks for an interesting read. Go post in the newbie section, introduce yourself and let us get to know you a lil. Then either provide useful info or go post in the tailgate.
 
Well, at least he bumped this thread to the top again so other new people can read it!
 
Somebody is on the rag! LOL

I love Seafoam it works great especially on stuff that has been sitting for a long time and is gummed up; ie chainsaws push mowers, 1967 classics mustangs!

Sometimes I mix some up in my Orange Juice in the morning, It's yummy!

Robert, you can always drink it then piss in the intake!:icon_rofl::icon_rofl::D

Disclaimer" I do not suggest or condone the drinking of SEA FOAM!":icon_thumby:

Sorry Otto, Do you own stock in Seafoam? There's no way in hell I'm adding that stuff to my gas/oil/vacuum.

Good for you. The rest of that have used it and seen it work will continue to use it.
 
I was suspicious of the stuff at first. But I got a can and tried it on my choptop a couple years back. Sucked part of a can into the intake via a vac line, killed the motor and dumped some in the gas tank. Let it sit a few minutes, started it and let it idle a bit. Shut it off and an hour or so later I went to leave. Talk about a smoke show... For the first quarter of a mile down the road there was nothing but a massive thick cloud of black smoke following me. Unbelievable the amount of smoke it was throwing out. Truck seemed to start better after that and run better without stumbling.

Naturally, I still wasn't convinced. I thought maybe it was something to do with whatever stuff SeaFoam is made of to make you think it got cleaned. So I picked up another can and tried repeating things the same way with my Ranger (at the time it had around 60k miles and was very well taken care of including full synthetic oil since aroudn 45k). Very little smoke and didn't seem to change anything.

Tried it with my F-150 (not sure how well the previous owner took care of the truck, I suspect it wasn't up to par), and got a good bit of smoke, not as much as the choptop, but the F-150 is supposed to have considerably less miles. Still have a bit of a hard start, but it seems to have helped the stumble.

I still don't think it's a miracle product, but it does seem to do some good and is not all hype. I recently picked up another can and have yet to decide on what test subject to try next, lol.

Oh, yea, I haven't tried dumping it in with oil, but I do use ATF in with my oil to clean things.
 
Yeah, saying that all of the smoke that seafoam produces is a product of burning it is complete bullshit.

you seafoam a high milage engine, it'll smoke like mad for minutes, a clean low mile engine will hardly smoke at all.

that, and the same high milage engine will smoke less and less each subsequent treatment, so clearly the smoke is not a product of the seafoam itself, but a product of the cleaning action it performs.
 
Seafoam now makes an aerosol spray. I read the can a few weeks ago and went back to see how to use it and of course we're out of stock. This version I believe sprays into a service valve on the fuel rail or a port. I think they came out with it to lower the risk of over filling a vacuum hose. I can tell by the smell it's as strong as Engine Fog. Make yer eyes water! lol

If it's being sprayed into the fuel rail, then it's not cleaning the vacuum/intake system at all. Same thing I pointed out to you when you posted in this thread before. Two separate systems.
