I have a 2013 v 3 avg 46mpg best 50mpg. I generally fill up at 400-450 miles avg 9 gallons. I never would let it get below 1 bar. Some say it will flash but I don't want to risk it. Not even on a regular car. It can be a very spendy problem. 2013 Prius v not V for the Prius v wagon 3
If you had a 2005 - 2009 you would be filling up with 1/2 a tank left if you filled up when the gauge shows one pip. My fuel gauge starts flashing at about 325 miles and at that point it takes about 7 gallons to fill a 11.9 gallon tank. (I averaged 46 mpg) Nexus 5X ?
