Hey Paul!
Math is not my strong side but a quick google search told me that there is 128 fl oz. in a gallon so 128/8=16
36.6/16= 2.28 Kw/hr worth of gas you turned into .4 Kw/hr (1.6 Kw for 15 min=.4 kw/hr).
That would be about 18% eff? That is actually not bad for a gasser turning a DC motor. Must be a pretty decent DC motor you are using!
