CO2 vs CO2/Nitrogen mix

Ok so i've had to do a bit of digging to find a place near me that does CO2 fills for my new kegging system. I found a place near by that sells what they call "Beer Gas" which they say is a CO2/Nitrogen mix. I was wondering what are the pro's and con's of a CO2/Nitrogen mix and is there anything special I need to know when using it to force carb? If I choose to go with just straight CO2 I was told by a buddy that I need to make sure I get "food grade" CO2? That sounded like BS to me as i've never heard of "food grade" CO2, anyone know? Thank you all.

Beer gas is ment for nitro stouts with creamer faucets or long running lines to push at a higher psi so you don't over carbonate..

So if I'm understanding you correctly I'll just need straight CO2. Anyone know if "food grade" CO2 is a real thing?

I get mine from a standard cylinder filler.. nowhere does it say food grade.. my buddy gets his from a welding shop.. I think the food grade is prolly B.S.

Thank you, much appreciated!

They keep the food grade CO2 in the back room with the rotor wash and elbow grease.....
