As most of us know, the TCH will report your gas tank as empty and cruising range is 0 after just 14gallons, meaning you still have 3gal of gas in reserve. So the trick is calculating how far you can really push your TCH before you run out of gas, because on those last 3gal you could be getting 60mpg in mostly-EV mode, or you could be getting 20mpg doing lots of full starts/stops, and you don't know how much gas is really left in the tank.

So last night, I got to 0 cruising miles at 502 miles, and I kept going until I had put 544miles on that tank before I filled up. I know I had at least 50miles left in the tank (and probably more because the car only took 14.5 gallons to fill up) but I was at Costco already.

So who in here has put the most miles in their TCH on a single tank of gas? Anybody go over 600 miles on one tank?
