I know some people swear by certain gas brands.

However, unless you're driving exactly the same route in the same conditions day after day after day (and putting a lot of miles on), it's next to impossible to compare one fuel brand to another in any sort of controlled fashion.

Comparing fuel/fuel additives is something that can really only be done in a lab, IMO.
