Its hard to believe that you trust your fuel gauge that much. They are not spot on and never will bw untill you are working with a compressed gas. They are there to give you an idea on when you should get gas. I dont trust mine as far as I can through the cluster. I have driven 45 miles with the gas light on. Thats just to show you how right they are. when I filled up I still had 2 gallons in the tank and it was showing passed E. If i have a 1/4 of a tank like you say. when i back up my drive way it shows 1/2 a tank. and when i pull up it shows E. Went on a trip 2 years ago in my old 4 door for 120 miles it showed Full. stoped to eat and when i restarted showed half a tank.
