Seafoam

what's everyone's opinion on the seafoam engine cleaner stuff? good? bad? waste of money?

As far as I know, it does what it says it will, but that's not always a good thing.

I wouldn't use it in my car.

yeah it seems like if the car is older, it could probably make things worse. i'm not planning on doing it, i just heard someone talking about it.

I use Seafoam in everything. Have used in older vehicles in hte crankcase to clean up sludge and varnish. Through the intake and in the fuel tank.
Also use it in the lawn mower and 2 cycle mix. Really makes them all run better.
SeaFoam is one of those products that do not rely on advertising or special pricing to sell products. they rely on personal recommendations which is the best way to sell a great product.
the stuff is for new and old engines.
