I posted a thread a couple days ago about gas cans. I'm thinking about keeping a couple 5 gallon cans on hand for the generator. Used to stock propane for my propane generator, but I gifted it to a family member after a hurricane a while back. Ian has kicked me in the butt to get on getting another. I want a gas generator for commonality with my vehicle. I'm curious how long you guys have stored regular e10 87 octane gasoline for. I'll be cycling it out in my vehicle, but I'm still interested in how long I can make it last.
I'd be leaving them filled to the brim, as I've found that helps with lessening the effects of expansion. Never had a problem with leaking when doing that. Should help keep the evaporation of lighter volatile compounds to a minimum, as well.
Internet says anywhere from a month to a year is the expected shelf life. I don't put much value in these figures as I've had a car run without issue after sitting exposed to the elements for four years with just a gallon or two in the tank. With all the temperature cycles and air space for evaporation to take place I'd say that the gas was exposed to pretty rough conditions. Even so, it still fired up and ran great.
