You wouldn't think gas millage is important with generators, but it is. I had 2 gens, one was a TS 5500 watt unit and the other was a Honda eu3000i 3000 watt unit.
Power went out for 14 days after a hurricane and I ran two houses. One house had the TS gen and the other had the Honda. The TS gen burned 3 times what the Honda did. Now I know they are not exactly equal, power wise but fuel efficiency can make a big difference. Not only is it cheaper to run the Honda but if fuel is hard to get, it's even more important.
