I have never been able to get more than 12.5 gallons in my tank - low level light has never come on but the message center has warned me several times about having 50 miles and then 25 miles left.

Am I really missing out on getting 4 gallons in each time I fill up? If so - why does my gauge not read only 3/4 of tank when I fill up?

Not really. First of all, 16 - 12.5 is 3.5, not 4. And if you're getting 20 miles per gallon, and you have 50 miles left in the tank, that's 2.5 gallons. So there's only a gallon unaccounted for. And if you're getting 15 miles per gallon, that's nearly 3.5 gallons. That would be all the 16 gallons: 12.5 + 3.5 = 16. There's a little inaccuracy, so that's about right. See my previous message for several reasons Ford gives that the amount of gas in the tank can seem to vary a little.

My wife drives it 70 miles a day and gets that. She doesn't have a lead foot like I do.I think it has something to do with greater altitude doing something. I know most folks would say that you get more power at sea level, but when we were at sea level. I didn't notice any gains. I think the air is colder up here, (I know it is) and more dense and that has something to do with it as well as my wife driving like the little ole' lady that she is. Also, 35 miles of that is uphill from 8000' up to 10,200 feet. Maybe she gets better gains by coasting downhill on the return trip.
