We have 3 different models, 3 different years, 2 different gauges, 2 L36s and an L67. Every one of them behaves exactly as harofreak00 described. From a full tank... when the gauge hits half and you look at your mileage, you think you're going to get 40 mpg. From there it goes fast.
FWIW, I have never run out of gas assuming I have 20-25 miles left when the fuel light goes on. i am probably overcautios, but i have no urge to find out what is at the bottom of my gas tank.
