This tank was spent driving up to South Lake Tahoe and back down. I suspect the pump clicked off too early and this was not a complete fill-up. It probably should have taken 13 gallons instead of only 11.

Averaged this with the following fill-up gives much more reasonable results, so I have chosen to record 31.77 MPG for both tanks:

336.5 + 402.3 = 738.8mi
12.164 + 11.091 = 23.255

738.8mi, 23.255 gal = 31.77 MPG
