those guys were able to drive
those guys were able to drive 150mi past the 0 mark - clearly way too much of a reserve - they don't trust us to get gaz when close to zero ? sicne the meter doesn't go negative it's really hard to tell how much you really have left, which is bad.
in my 2014 Prius (didn't know it has a 11.9gal) I can usually put close to 10gal (which I assumed was the capacity.
1gal reserve should be safe and rpetty standard on other cars - that 40mi on hrybrids!
