road trip

Car 2014 2.0T Auto - 90%+ Hwy - Avg Speed 70 mph - Jarrell, TX to Jacksonville, NC
My mileage for this road trip is as follows:

1st fill - 300 miles/10 gals = 30 mpg
2nd fill - 319 miles/9.8 gals = 32.55 mpg
3rd fill - 350.4 miles/10.6 gals = 33.05 mpg
4th fill - 430.3 miles/14.3 gals = 30.09 mp (1.5 days of city driving)

NOTE - all calculation were done with mileage from the car and fuel slips.

How many of you reset you Avg Mileage when you fill up on gas?

I tried speeds from 60 to 80 and 70 seems to be my sweet spot. According to may scan gauge I am not in boost, the fuel trims are spot on and the cat temp is within normal range. Checked the oil and it would be hard to tell if any was used. The oil life dropped about 10% in 1,400+ mile trip.
