To remove as many variables as I could I fueled up at the same pump,
at the same time of day and the same fill rate no top off, early morning. Target speed was 65mph +-3mph, I was being past by most vehicles. This was on I 10 toward Tucson, it was +100 deg F, the AC ran the whole trip (blowing out 40 deg F air). The egt was 700 deg F +- 25 deg, boost was a constant 4-5 psi.
56 miles of in town driving and 218 mile on the interstate.
9.748 gallons were used. 28.108 mpg from my home in Mesa to Marana and back.
