Yesterday, i drove 104 miles, mostly of rural interstate travel.
Used 7.221 gallons of Shell 93 octane E10.

I calculate 14.4 miles/gallon.

Assuming the 235-75R15 tires a re bit smaller rolling radius than what hte speedo is set up for, then that would probably reduce it to about 13.1 mpg. I have not made that correction calculation.

Also running without air cleaner, air conditioner ON and full blast for full duration of trip. I didn't exactly practice good fuel economy driving habits either.
