I use a 30 gallon drum to buy my gas and store it at my property. I go thru about 3 drums a year. It is always pre-treated with a stabilizer product so I never actually put any in the lawn mower, gator, portable generator, etc for storage. And since most of my stuff gets started occasionally and used during the winter months, I don't drain them, fog the motor, etc. Haven't had a fuel related issue with any of them for years.
