The best 50 mile segment I've achieved is 30.3 mpg. I've seen multiple 28+ MPG segments before and after this one. Here were the conditions: After break in, 87 octane 10% Ethanol, highway, 18" snow tires, below 50 degree outside air temp, no power modifications, no passengers, and 65 to 70 MPH.
With the summer tires and higher outside temperatures the best I've been able to get is <27 MPG. Running on 88 octane 15% Ethanol doesn't seem to make any difference in my non-scientific "testing".
