Everyone seems to be confusing the 93 octane "rating" used on the certification. If I read it correctly myself the 93oct is the RON measure. Fuel at the pump is (RON+MON)/2. MON typically ends up about 8 or 9 pts below RON. So, the fuel used to certify the numbers for the 2015 Mustang is most likely 88 or 89 and not 93.
