If you find out that "boost is fun" while driving Blue you'll lose the competition then and there.
But, boost IS fun! Man, Blue can be FAST! And it can TOW! It made the 200 mile trip on Saturday so easy. Going over pulling the empty trailer at 70 MPH on the turnpike it only downshifted out of 6th for a hill once, and there are many big hills. And it got mid-14's doing it.
Coming back I locked it out of 6th and it handled the car and trailer so easily, and still got about 11 MPG running 70.
But, I filled it up with 91 octane for that trip, and it was almost dry when I filled up. It probably still has 20 gallons of that mix in the 34 gallon tank, so when we fill up with 87 octane Blue is still going to be sipping high test. And that gives it a bit of a boost on MPG, although not a lot in a non-towing mode.
