SeaFoam doesn't improve your mileage, it cleans stuff. The result may have been improved mileage, but it wasn't the SeaFoam that did it.
Most additives are only there to cover stuff up. The only things that I'm still slightly intrigued by are Zmax products, basically because of the marketing demonstrations that I've seen where they run a load meter on an electric motor with thermal protection, and with standard lubes, it clicks off, and when they put ZMax lubes on it, it runs up to high load, backs down a bit, and steadies at middle load, never clicks off, they remove the lube and it stays running for longer than the show went on.
Their claim is that ZMax provides a "dry film lubricant" to bearing surfaces. I have yet to test it.
