remember the old Jackson Brown song "Running on Empty"? well that is me. I have been running on empty fo 20 miles now and I expect to be able to keep running on empty for many more miles. Every time I fill up my 2010 Prius, I KNOW there is still 2 gallons or 100 more miles in the tank. I think it is stupid that the computer has us fill up when we have that much still in the tank. So when my display read "0" miles to the next fill up, I zeroed out my Trip B odometer and kept driving. I have 20 miles on "empty" now. I will start carrying a fuel can tomorrow. I want to know how many mile I can go on the official 0 miles to fill up, empty mark. I think Toyota is mistaken to have us all fill up with 2 gallons still in the tank. When I run out of gas, I will have almost a mile of EV mode range, right? and then I will have my 1 gallon gas can that I am going to start carrying. Hope I am not too far from a gas station. Can anyone tell me why I should NOT attempt this on my precious new Prius? I don't see why not. If I get up to 80 or 90 miles "on empty" I will be satisfied and fill up then, but not before!
