2020-09-08	507.7	7.051		72	"Discrepancy between Prius computer and the receipt. Computer says 72 MPG, but trip miles and gallons of gas equals 67 MPG. I would expect the opposite, where gas receipt shows higher miles due to ignoring electrical aspect, so like 80 MPG, but the Prius would say 72 to account for however many kWh we used. Adjusted the gallons of gas from 7.548 to 7.051 to match the computer’s 72 MPG, since I don’t know how reliable the auto-off pump mechanism is at gas station. Need to research."
2020-09-11	372.2	6.39		58.25	"Another issue with computer vs receipts. I traveled 372.2 miles, and filled 6.39 gallons. This makes 58.247 Mpg, but the computer claims 48mpg, which would’ve been 7.754 gallons. This doesn’t seem possible, since my tank wasn’t that empty. Weird ****."

2020-09-17	395.9	8.019	$2.449	49.37	"average speed 41mph. computer says 54mpg, but again the damn receipt says otherwise."
2020-09-21	409	7.051	$2.489	58.01	"I give up. Will only do receipts from now on and ignore computer. This trip was about half with the old tires, and half with new ones. Curious to see results for new tires and will have to calibrate odometer perhaps."
