We have a couple gas generators that are stored away 99% percent of the time. When we do use them we need them to work right now with out issues. One of the biggest problems with long term storage is fuel problems related to the ethanol. The best thing that we found to alleviate this issue is to not run fuel with ethanol. We run aviation fuel in our generators. Aviation fuel is ethanol free, and has a little higher octane rating than auto fuel and there for will store much longer than fuel with eethanol with. We started using aviation fuel several years ago and have great success. Our generators start and run great on this fuel even after being stored for 26 months with the av gas in them. Fuel costs are only slightly higher using av fuel considering the amount used to power a generator. We buy our fuel at the local airport and when we fuel dads plane we might take a 5 gallon fuel can to fill just for generators so their ready for the next time.
