Yeah I have had similar problems with my fuel gauge....the needle is accurate but the digital readings are off by a lot...after the reserve fuel warning comes on around 50 miles to E, it then drops about 5 miles to E every mile...annoying when having to risk it! Also, when I fill up it says I get 20.1 mpg and will get 380 miles out of the tank but I only average 19 mpg and get about 280 miles from a tank. I asked Ford about it and they said that the sensors in the tank tend to do that and to not even pay attention to the digital readings, pay attention to the needle and I'll be fine.
