Ateup, I understand the point. I pay close attention and do this on my daily routes and have made it work for me. Part of it is gas is nearly 10 cents a gallon more in Nashville where I work, but that is secondary. I did this since I started driving in the late 70's.
However... When I am not in my normal areas, I rarely see the low fuel light come on cause I fill up at a quarter tank. When not in familiar areas I don't push it at all.
On the daily routes it provides a challenge for me...LOL.
