SeaFoam, 1. Gas and diesel stablizer, de-icer, anti-jell, varnish cleaner, carbon cleaner, lubricant, cleans all internal parts by being added to fuel.
Too many claims. Too good to be true and it is supposed to do that by adding it to every 4th to 10th tank fill of your car gas.
When used directly on varnish it does nothing as in the carbon test.

I would expect it do so something however mild in the carbon test.
Mkd55 - took the carb apart and cleaned it all up.i'm sure the biggest problem all these engines have is they are only used seasonal.the carb cleanout helped to restore some of the running characteristics and thats all
That should be enough to run right so no need of additives.
Mkd55 - i put injector cleaner in the chevy and it cleared up within 10 miles of driving.point being i believe cleaners can be harmful if used the wrong way as well as helpfull to some extent in a lot of instances.this year
Was that SeaFoam or a dedicated injector product? I ran an 84 VW Rabbit for 280K and occasionally put in an injector cleaner or Mystery Oil occasionally. Never noticed anything.
Mkd55 - started surging and running erratic.i tore the carb off and cleaned and blew everything out with compressed air.it started and ran somewhat better but still had the surging going on.
The cure for surging is cleaning the carb, occasionally a gov tweak..
Mkd55 - i took the plug out and brought the piston up to top dead center and poured about 1/2 oz of seafoam right down the spark plug hole.i put the used plug back in and let
Seems like a weird way to clean a plug and I also don’t believe it.
Mkd55 - after about 8 or 10 squirts in the carb throat the engine smoothed out and started to run at increased rpm without stumble.ran like it did when first bought!
8-10 squirts of SeaFoam through the throat to cure a surge. I don’t buy that it was due to SeaFrom.
Mkd55 - using seafoam in all my power equipment gas and believe that the benefit far outways the cost
Rebuilding a carb and taking care of seasonal maintenance like taking out the gas during the off seasons keeps my stuff going without the cost of additives.
.Mkd55 & - one claim of seafoam that i find beneficial is that it has lubrication qualities
sscotsman - causing the float to stick
SeaFoam does seem oily and may have a lub benefit but if a carb is acting up I want to nail it for sure so remove it and clean it. In a moment of weakness I did try SeaFrom on what I thought was a sticking needle problem. It did not help. I took the carb off twice to refit the seat but the problem did not cure. The third time I changed the needle and seat and it cured.
For carbon buildup the only reliable thing I’ve found is to remove the head and go at it. I’ve gone through three cans of SeaFoam and I can’t say it does anything useful. That’s discounting whatever claims for being a stabilizer as I always use fresh gas, use gas shutoffs and drain equipment when not in use. That seems to work reliably.
