Got 31.13 MPG this time, got 9.099 Gallons of gas (93 Octane) and went 283.3 miles before getting gas. I will stick to 93 octane from now on since there's no cost difference between 91 and 93. Also I drove it hard this time

and I am surprised I got that good of a mileage out of tank.

I would say 90% of it was highway.
