Now that I've got my little generator working, I want to make sure it's always ready to go in case of a power failure. How often should I run this thing--once a week, twice a month, once every 3 months? And for how long--5 minutes, 15 minutes? Should I run it under load, and if so, how much load? I've got a 5 gallon can of gas at the ready, and it's stabilized with the blue marine grade Sta-Bil, so I shouldn't have a problem with stale fuel. We have a big diesel standby generator at work, and it's programmed to automatically fire up and run for 30 minutes every Saturday morning. But that would seem excessive for this little home genny. What do y'all think?
