Stabil for the win. Seafoam performed awful (see 3:40 -4:15)
Sounds like good advice but there is no non-ethanol fuel within 40 minutes of me. I've been using Stabil products for 20+ years and in my experience ethanol gas sitting in multiple tanks for nearly a year has caused zero problems. Heck I just started my Snowblower with one pull on gas sitting since March and now it's October.None of the products extended the life span of gasoline with ethanol. All the products failed there. Sta-bil did great however with preventing corrosion.
You need to use non-ethanol fuel or use up all the fuel (w/ethanol) within 1-3 months so you are always working with fresh fuel.
BTW, Project Farms testing took years for this video also.
