FYI, not a good thing to do to your car.

Aside from picking up any crap at the bottom of your fuel tank, the fuel also helps cool the fuel pump. Either way you'll probably end up killing your fuel pump prematurely.

Understood!

Generally speaking it's a bad habit to run the tank that low on a regular basis. I get antsy when I'm down to 1/4 tank!

Let me add, that I don't do this on a regular basis, it just happens sometime using the car with daily driving.
Didn't realize that this would start a flame.

Absolutly!!! Even if you did you'd be fined. All that other crap is urban legend and means less than nothing!

Lol I ran my Impala down to the bare minimum for 100,000 miles. Either Ford makes crappy fuel pumps that you're worried about or there is nothing to that myth. The engine was still super smooth and the fuel pump never had issues.

The Mustang is no different, IMO. I've run down my fuel gauge to less than 5 miles to E probably a dozen times now. It still always takes about 15 or gallons, sometimes a little less.

Agreed! Same with my last car!

Just FYI - I remember seeing a TSB where some new Mustangs would suddenly die when low (but not empty) on fuel. If I remember correctly, there is a pump that transfers fuel from one side of the tank, over the axle hump to the other side, where the pick up is. I believe it was this pump that was prone to fail. I'm sure most of the cars that had the problem have already been found and fixed.

If I remember the manual correctly, me thinks the computers are supposed to measure only 14 gallons of approximate fuel range then you have 2 gallons left to get to a watering hole before the fat lady has sung and your horse is done-zo.
