In order to net the same energy output (assuming mechanical and thermal losses are the same or changes are negligible) you have to increase the amount of fuel to equivalent gasoline energy levels with the additional appropriate oxygen. The mechanical function of an engine is essentially an air pump. Your not changing the pump by changing the fuel type. Your going to move essentially the same amount of air volume (oxygen). A forced induction engine can make additional use of the fuel by increasing positive pressure and making use of the greater knock resistance. So additional appropriate oxygen.
