I figured I would take complete advantage with all the experience here regarding generators and I could get a good answer to my question. I have two generators, one that is used often for camping and around the yard, and another larger unit that I purchased recently for home use during a power outage. The larger generator has been properly broken in and had the initial oil change. I have been running it quarterly with stabilized full for about 20 mins or so with a 500 watt load. On my last exercise run, I ran it completely dry...out of fuel. So now my question... Is it a better practice to leave it empty and not do any more quarterly runs and just fuel it up when I need it? OR Refuel it with stabilized fuel and continue to run it quarterly? I know a little about a lot, but can never make an adult decisions like this on my own. Thanks in advance.
