I have a long commute to work daily. A combination of me forgetting to fill up and me playing a game to see how far I can go without running out of gas, I ran it pretty low last night. The display said I had 6 miles left. The needle was on empty - had been for awhile - and I went about 12 miles with the gas pump light lit up on the dash. I wonder how much further I could have gone and if the display goes to 0 before actually running out. I reset the odometer everytime I fill up. Would like to go over 500 miles on a tank. Have gotten well over 400 but you'd probably have to drive 30mph highway the whole time to do it. Nice feature displaying miles left - not completely accurate but good compared to nothing.
