Seafoam vs. High Miles

[Car Nut]

I'm pretty interested in Seafoam, even though I don't really have any issues at all with how my car runs. My idle is fine, revs are good, and my mileage is about as expected. I have over 143,000 miles, so I'm sure there is some carbon build up to some degree.

Seafoam may expose worn seals that have been covered by carbon. Is this a big risk? I'd hate to ruin my current good luck, by cleaning things too much.

For those that have already used Seafoam, how many miles do you have?

I did it with 131,000 on the clock, and no negative feedback here.

Mine had about 158k on the clock when I did it. Nothing negative to report, works great for not much money.

Will seafoam clean out the intake manifold too or do you have to pull that off to clean it?

 

[revhead347]

It cleans some of the oil goo out of the manifold, but not all of it.

i did it today on a buick century with 108,000 miles and it smoked for a good 5 minutes while driving...sweet action!

My problems started with Sea Foam

please elaborate - I am thinking of trying some.



and i think there is a sea foam comparable product that is in an aerosol can that folks use for spraying out TB's, intakes, etc. it has a kind of unrelated strange name, as i recall.

 

[Car Nut]

Correct! There is a Seafoam aeresol spray, but that's not the right product. The Seafoam in question is in a '50s looking can with a lid that unscrews. I bought a can today at Discount Auto Parts for $6.00.

Rude, what was the problems man? Gotta know details: problems, install procedure, etc.

150+K no problems. Lots of smoke and an immediate imporvement in the cars performance.

 

[Blk05Retro]

I had improvements! I put 1/2 in the manifold, 1/4 in crankcase, 1/4 in the gas tank.

One in a million ....

I haven't used the product yet I just ran a bottle of lucas fuel injector cleaner B4 all this seafoam tech started. after a few more normal tanks I'll try the seafoam product.

The idle was smoother right after i used it but since then the car has been running sluggish and poor gas mileage

How much Seafoam did you use and where all did you use it? Need to know how to compare your experience with others.

Some people put varied amounts in the crankcase and intake, but I don't think it matters so much in the tank. I can see where too much in the crankcase could cause issues, especially on a well worn engine.

I used Seafoam on my Grand Cherokee last month. It has 240,000 plus miles on the clock. Runs smoother, and I picked up 2-3 MPG. It is my DD and I drive 60miles one way to work (Highway) and at about 80mph and I am getting 23mph.... I used half of the can thru the brake booster vac line and the rest in the tank.

i seafoames my stock intake (before i replaced it with the cobra) and i can say it did a decent job cleaning out the gunk. in the spots where the seafoam hit it (bottom of the runners) it was a lot cleaner and smoother then the areas where the seafoam didnt touch it (top parts). there was some serious 125K gunk buildup too

 

[Car Nut]

JUST DID IT!!!

No problems at all. I put 1/2 in the intake using the Brake Booster line and the rest in the tank. Once I put 1/2 in the BB line, I shut it off and waited about 15 minutes. Cranked it up and it idled a bit funny, but spit out a decent amount of smoke. I expected more smoke, but good to know everything is fairly clean already.

I keep my car serviced regularly with oil changes, tune-ups, annual fluid changes, annual fuel injector cleaning, etc. In other words, my car runs pretty good and has been very reliable.

I'll have to wait and see what the benefits are over the next week or so. I've got some long business trips coming up, so that means a good bit of miles.

looks like I might have to try this stuff.

 

[CArkid0101]

how much is it generally?
