Brand of Gasoline

I get a good 3-4 MPG better in my car (either that, or more power should I
choose to drive it that way) by using premium in my 2012 Sonic 1.8 that
calls for regular.

Premium vs normal gas would only matter if you were at WOT such that it
would have to retard spark to avoid detonation on normal gas. Otherwise,
they would be identical within the accuracy we can measure at th pump.
