Maybe I am missing something, but what benefit is there in trying to see how little gas one can drive with. I won't be getting my hybrid until next week, but I can't imagine keeping the tank as low as possible.
I am not sure, but I think nothing good can come out of guessing wrong and running out of gas (except being able to brag about driving around without any gas), but something bad can come from not having gas.
I could be wrong, but if you are driving around and for some reason the battery system has a problem, the gas in your tank can be the difference between a ten mile drive or a ten mile walk to get home.
I know gas is expensive, but if you fill up today or fill up next week, the cost is not that much different.
I was taught to try and never let the tank get below 1/8 fill, a lesson I've taught my children.
What am I missing here?
Are people concerned about the weight of the gas in the tank hurting their MPG?
