As you are all aware from my past posts about my car burning oil.
I decided a couple of weeks ago to do the seafoam thing, which I did and never really saw any great results, but I done it.
The only thing that I did see was that my oil pressure has gone from a little below the half mark to a little above the half mark. I guess it did something. I have about 300 miles on the motor since I put seafoam in the engine so an oil change is in the very near future.

Anyone see any results or comments on seafoam? Is it worth using again one day or is it just a pile of hype to sell the product.

Where did you put the seafoam. As for the oil pressure, the only way to really know is to put a mechanical guage on it.

Did you change oil afterwards? Or are you running on thinned down oil?

Although Seafoam is used as an induction cleaner and fuel system cleaner we found it works well for decarboning pistons and rings. This used to be a huge problem with Chevette engines and Suzuki 3 cylinders. The rings would get jammed with crap and make them loose compression. We have also had success with Prius hybrid engines due to their start/stop operation. GM used to sell a very good tip end cleaner, used the same way but took it off the market due to rumors of storage mishaps.
However, there is a way to make it work. This only works engines that you can get the pistons level. On Prius we raise the back of the car on a lift. Remove all the spark plugs. Then move the crank by hand to get the pistons even in the cylinders. With a funnel, add about 4oz. to each cylinder and let it set that way overnight. Then we use a small hose on a brake vacuum bleeder to remove any Seafoam left in the cylinders. Then very important. Drain the oil and change. We have a oil charger that we use about 1/2 quart of oil to flush the system. Without one I would change the oil again after running a little with a new filter. Seafoam will find it's way to the crankcase and badly strip the oil. Don't run the engine after this without changing the oil. After we change the oil we disable fuel pump, crank the engine around without the plugs with rags, weighted down, over the plug holes to remove any left after vacuuming. Reinstall the plugs and fire it up. We have did before and after pics with a bore scope and it does a great job of cleaning the pistons up.
