OldDog and others have hit on some of the things that may be cumulative to the total WHY, but the mileage is improving. One strong possible is the advanced timing as many of the newer cars computers start with full advance and then each sensor retards the total. Browns gas has a small 02 content plus it carries moisture and the 130 octane level all makes the fuel charge more dense while NOT retarding the timing.

I did not stay at a Motel 6 last night so just winging it here but all the things above should be some help. I do not know why some feel that separating browns gas from water is so difficult or takes so much amperage because it is damn easy. I can produce more HHO than the smaller cubic 4 banger engine can use, more accurately I can not remove enough gasoline from the fuel map so engine becomes very rich. The engine is running on enough of the browns gas that if you turn off the HHO the engine will die and you can not restart until turning browns gas back on or returning gasoline delivery to the stock amount. Either way I am talking about a 25% increase in gas mileage as an average believe it or not. The engines power is up a little bit too, about the same turning the AC on and then off on this 4 cylinder engine (Saturn Vue).
