2018-02-01 374 12.18 $2.4 30.71 "Kum and Go Monuement. Pump 7. Slow fill, single click. Regular Octane. DWL, EOC."

2018-03-02 377 11.81 $2.87 31.92 "Filled with 91 octane now. Fuel economy of this tank though is last fuel of regular octane. Next tank will represent 91 fuel. Cost delta per gallon is about .50$. Will increase in FE justify?"
2018-03-08 351.7 11.57 $2.87 30.4 "Data for first tank run on premium. Had several very windy drives, noticeable impact on daily trip FE."
2018-03-14 342 10.939 $2.129 31.26 "Had to refuel in Denver, Soopers. 91 Oct"
2018-03-25 383.2 12.8 $2.39 29.94 "91 Octane, but last re-fill DW did not reset odometer until later, unsure when. Disregard this tank average."
2019-08-16 344.5 10.522 $2.449 32.74 "First tank in a long time with trying for good FE. First tank with UG again, calibrated mileage first, this was the tank used to calibrate FE. UG estimated ~10.2 gal used, same pump at station, slow speed, single click was 10.522 gal. UG showed avg of 36.2 at the end, this difference in gallons does not seem to quite explain that difference in FE but we will see next time. DWL, E-on-C, turned off at some lights, pulsed AC if needed."
2019-08-25 326.4 10.611 $2.429 30.76 "Pump 4 at 7-11. Slow speed, 1 click, 85 oct.

Checked fuel calibration again since hand calc was at 30.7 and UG still had 34.1 for the tank. Adjusted fuel calibration ratio to 1.02, will check again with next tank. DWL, coast when able but had to drive 190 round trip from airport, highways speeds."
2019-08-31 342.6 10.918 $2.49 31.38 "Same driving techniques as before. Same pump and station, slow and first click only.

UG trip MPG: 34.4 Hand calc: 31.38. Adjusted fuel calibration to get ratio of 1.025 now. Since all these were from the same pump/station/conditions and the UG is overestimating still, I will simply adjust the ratio manually to get close to hand calc."
2019-09-08 328.2 10.925 $2.49 30.04 "Wife drove more on this tank, she does not hypermile at all, lead foot also."
2019-09-16 365.9 11.626 $2.46 31.47 "Second fill at Soopers Monument, same pump, slow, 1 click. UG mpg 33.1. Left fuel calibration alone at 1.074. Seems to still be optimistic in UG, unsure. Range also optimistic but unsure of that's all from MPG differences or using factory capacity vs whatever the cars range calc uses."
2019-09-21 370.5 12.413 $2.57 29.85 "Filled at 7-11 this time. Not original pump, slow 1 click. UG read 32.3 mpg. Range was too optimistic, reduced fuel tank size to 15.0g."
