stabil gas treatment vs seafoam for storage

I never had any trouble at all with Stabil, but after having to use Seafoam on a "newly aquired (neighbor gave me a self propelled) lawn mower", I didn't see the need for two different additives sitting around, so I just started using Seafoam with excellent results.

With Stabil, you shouldn't use more than is recommended, with Seafoam it doesn't really matter.
