I love my 2009 Sable Premier. One thing I've noticed though is that the miles to empty message comes on and says i have 50 miles to empty when the fuel gauge is at about the 1/8 mark. When I fill it up the most I can usually get in the tank is 16 gallos. This past week I ran it until it said I had 1 mile to empty - I filled the tank and was only able to get 17 gallons in the tank - meaning I still had 3 gallons (or about 75 miles highway) left in the tank. It's not really a problem but I'd just like to know if that's a reliable indicator of my fuel level.
