Does it matter which gas brand you buy or are they all the same?

My last tank I only got 31.5 MPG where I filled it up at a non-branded gas station. Before that I filled up at Exxon and I got my highest ever at 36 MPG.

My initial thought was that maybe the Exxon gas was better quality or had less ethanol? Maybe I just didn't drive as well on my last tank.

Has anyone else noticed if the gas brand yields better FE?
