The refuel warning seems to come on at a little over 15 gallons fuel used. Since the tank capacity is 17.3 it would appear that Ford has built in a very generous buffer supply at about 2 gallons.
This is my only complaint about my Fusion. What good is that extra 2-3 gallons of fuel if you dare not use it? I'd rather it told the truth. Still, it has plenty of range, I've gone 430 miles once and only filled 14.5 gallons. I just think it's a waste if capable of more.
Anyone want to try and see how many more miles you can really go after it says 0 miles to go?

I see a lot of people having to frequently use their brakes on the freeway because they are tailgating the car in front of them. Because they leave so little room they have to brake frequently, they can not just coast for a moment to adjust to slight changes in speed by the car they are behind.
But I think going 80,000 miles on front brakes is also dependent on where you drive. To go that far you would probably need to do a lot of freeway driving (without tailgating and riding your brakes).

I don't think I'd want a refuel warning light to come on only when the tank is empty. 2 gallons seems about right...that allows you 50-60 miles. You don't have to buy gas just because the little light comes on, I assume the fuel gauge is not indicating "empty" when the light first comes on?

It also prevents the fuel pump from running dry and causing premature failure.

Actually the 2010 Milan (and I presume the Fusion) have a pretty accurate mpg calculator and it tells you how many miles left on tank starting at 50 miles left I think. I managed to put 15.3 gallons in when the calculator said zero miles left. So it is not exactly as vague as simply the needle points to empty. I will need to check the manual for tank capacity but I am fairly certain that I read 17.2 or 17.3 gallons. I'm not sure whether the sensor knows when you refuel or simply reads a float level in the tank. I suspect the latter. The calculator then converts the gallons left into miles left from it's memory of how many mpg you average.
The point about keeping the fuel pump under liquid is a good one although I suspect they could just locate it in a sump off the tank so that it would be wet even when the fuel is very low.
In time I'm sure I'll test the limits beyond empty but the car is so new I don't want to insult it by running out of gas.

A guy I used to work with told me that whenever he got a "new" car, he put a can of gas in the trunk and then would drive it until the tank was completely empty so that he would know how far he could go before the tank was really empty.

I like that idea and will try that in a few thousand miles. A reminder to Fusion/Milan owners with the new capless fillers: a special funnel is provided (under the trunk floor cover) to allow portable gas cans to be use to fill the tank. They caution that if you insert the spouts of portable gas cans they may damage the capless device. The funnel is a clear polysomething color and strapped in with the jack under the trunk floor cover.
I did read the owners' manual again and yes the capacity of the tank is 17.5 gal for FWD and 17.2 gals for AWD for the 2010 models.

The low fuel warning is displayed when you have about 50 miles of range left.
If you turn it off and don't fill up, it will pop back every ten miles later.
I once went at least 7 miles with the DTE reading zero in my Explorer.
Had no choice, I was on I-80 and had to get to the next exit.

That's the stupidest idea I've heard in a long time. Just get fuel before it gets to zero.

I disagree. Carrying a portable tank and running it to empty is an excellent idea. To me, it's peace of mind to know how many miles you've got left when the low fuel light goes on or the computer reads 0 to empty.
It can also be the difference between filling up in a not-so-nice part of town versus a station in a better part of town. You NEVER know where circumstances will lead you when you're running out of gas.
Of course, it shouldn't become a habit, especially with the damage it can do to a fuel pump (by letting it run dry or clogging it with sediment that collects at the bottom of a tank), but knowing the true range is a good thing, and from an old cartoon, "Knowing is half the battle."
