Fuel octane is governed by the U.S. Government. 93 octane is the same 93 octane if you get it at Chevron/Shell or Kroger/Walmart. My father works for Kroger at Cincinnati Head quarters and has informed me that they outsource their fuel from Shell. The only difference between fuels from i.e.: Chevron, Shell, Texaco, Mobil, Kroger, WalMart/Sams Club etc... are the additives that are added. But the octane is the same.

There are too many variables in dynoing a car, running it's fuel nearly dry and adding a different brand and redynoing.

Edit... And a 15-20whp lost is, honestly, just not believable.
