I was wondering, if your kegs are carbonated but you have ran out of CO2 can you use "Beer Gas" (75% Nitrogen/25% CO2) to push your beer even though they are regular faucets and not the stout faucets? We are doing an event and I have no time to get a 5lbs. CO2 tank for the event but I do have a 5lbs. "Beer Gas" tank that is full. I am assuming this will be fine but thought I would get your thoughts. Thanks.
