our generator is a honda 6.5kVA unit ... when in use during blackouts, our load is around 1kW only and i observed it consumes around 2 liters of gasoline per hour ... it has around 20 liters tank capacity but we use it only from 6pm to 12mn
we don't use heavy loads such as aircons, flat iron, and water pump when genset is in use ... it seems 1kW (maybe even less) is just about the average load with 1 ref, 1 chest freezer, hot&cold water dispenser, lighting, 2 tv's, 2 efans, 1 desktop, 1 laptop, modem and router, cellphone chargers, and 1 small aquarium
i have not made real observation with aircon use, but i believe it could cost around 1/2 liter per hour (similar to the additional fuel on an idling car with aircon on) ... as a small 1 hp aircon is around 1kW, i think our genset will consume 1.5 liters/hr without load, and 0.5 liters/hr for every additional 1kW load
