Except for automobiles, every drop of gas I buy is ethanol free and gets Seafoam.
I had several pieces of lawn equipment almost die from the carburetors gumming up. I started using Seafoam at double concentration and by the end of the summer, they were all running like sewing machines. (I then cut back to the recommended concentration.) When I found a station that sells ethanol free (labeled "recreational gasoline" and sells for 150% of the price of 91 octane) I went to that exclusively for my small engines.
