With only one or two minor power outages this past year, our WEN 2kW inverter generator has sat mostly unused for over a year, with the same gas + regular Stabil (I kept 100% topped off for storage). Wanted to run the gas out (1 gal in generator + 1 treated gal in container), so I ran the generator for over 8.5 hrs using a 1.5kW ceramic heater. Started on 2nd pull, ran perfectly; no smoke; no consumption, etc. I've got about a quarter tank left and I'm planning on running it out, then filling the tank to the brim with treated fuel, just like I did over the past year. I'll probably burn the gallon of fuel every 6 months, instead of waiting a year. What do you guys think?
