113 degrees and you didn't run A/C? Isn't that getting just a bit too anal to try to save fuel?

By the way, Mythbusters tested A/C on, A/C off, and windows up, windows down. Over 45 mph you do not lose mileage with windows up and A/C on as opposed to A/C off and windows down.

I get the best mileage on BP also - and I get about 2 mpg difference between E10 and pure gas.
