The fuel gauge is hopelessly conservative. Best practice is to calculate your MPG by hand, reset the trip meter with each fill up, and do the calculations mentally on how much range you have left. The tank capacity really is 5.5 US gallons.
It is not a great idea to frequently run it down to where you put 5 gallons in, the fuel cools the fuel pump so really low fuel in the tank makes life harder on the pump. The fuel level you are filling up at is fine on the pump.
I have the same experience with the low fuel light being on, and only putting in 3.5 gal. Knowing my MPG from calculating it almost every tank makes me confident I can run 200-250 miles before a fill if needed. Im getting 55-65 MPG depending on my average speeds, being at high altitude and a lightweight guy makes that possible. At sea level 50-55 MPG is typical for me.
