I often get 10, most of the time almost 10, once in a blue moon 11. The kicker is I often camp where I am using my generator. No good checking gas milage after turning the generator over. Granted it does not use that much but more than none. Now I got to the point I check more to make sure the engine is consuming as normal but no longer keep a log. When I check I base on full tank of gas filled on level ground, or better a couple tanks of gas over known miles.
