I know that there are many contributors to gas mileage and is hard to check it precisely, but I was wondering if the major brands of gas (Shell, Exon, Mobile etc.) produce better mileage than the non-major (convenience store) types?

So let me ask this:
If you could buy name brand gas at the same price as a non-named brand,
which would you choose?
