Filled up this morning, topped it off. To the brim.

Drove 105.1 miles (adjusted 10.48% from 95.2 on the odometer because if tire size) from the gas station, to the salvage yard, and back to the gas station, same pump.

Filled up, topped it off. To the brim. 3.2 gallons.

Unless my math is way off, then I just got 32.85 MPG for this stretch. How is that even possible???

The trip was I'd say about 92% highway miles and the rest rural "city" traffic. Engine light is still on with the following codes:
P1171 - Fuel System Lean During Acceleration
P0157 - O2 Circuit Low Voltage (Bank 2 Sensor 2)
P0137 - O2 Circuit Low Voltage (Bank 1 Sensor 2)
(I'll research these later)

Power mode OFF.

but at the same time.
