I've had my Aviator for 2 months now and have never been able to completely fill up the gas tank. The owners manual says that it has a 20 gallon tank, but the most I've ever been able to get has been maybe 15 gallons.
I even ran the gas down to where I only had 25 miles left until empty and when I pumped gas, I was only able to put in about 13 gallons before the pump began to stop. This is with an average of 15 mpg during that trip.
My local dealership said that Ford engineers are working on a solution. They gave me another Aviator, while mine is in the shop for the second time with other issues, and it looks like this one isn't getting the full 20 gallons either!
Is anyone else having this issue?
