I haven't had enough tanks yet- but so far: low fuel light came on at 1 bar, drove about 20 miles and there was about 3/4 gallon left in my tank. haven't seen the bars flicker back and forth at all, but the other 2 times I refilled my tank at 1/4 tank/4 bars. I'm down to about there now, I'll keep an eye on it and post if I see anything weird going on- I was waiting for 1 bar anyway before I filled up.
