For my Easter trip home and back, I drove 556.9 miles on a tank of gas in the Camry, my farthest ever. I still had about 2 gallons in reserve (as I filled up five or so miles after 0 miles to E, and 30 or so after the fuel light came on, with 14.5 gallons, totaling 38.3 mpg), so I could've gone 600+ miles on that tank with a bit of fuel to spare. This was mostly 70-77 mph with the a/c on, driven pretty efficiently but with no particular pains taken (and little wind for most of the trip). I used Phillips 66 E10 87 from the same pump for both fills, but could've likely squeezed a touch more out with ethanol-free 87 if I'd known I was going for a record (that's a fuel I've never tried in the Camry; it's all been E10 87 every time). I'd gotten back to town on the single tank, and it was late in the evening, but otherwise would've pushed for 600 miles, a number I have not yet achieved. What's your record mileage on a single tank?
