Perhaps that was a factor in the conflict between the initial leaked fuel economy and the officially released number. It could be that the initial 27mpg was based on using premium and the revised 25mpg is based on regular.
I have a Mazda CX-30 Turbo that gets one set of power and fuel economy numbers on regular, and a better set of power numbers on premium. My personal experience has also been a slight increase in mileage when I give it the full 94. The engine adapts to what you feed it.
