Hey, I've been wondering about my mileage also. I get 250 to a tank, so about 19 mpg. I had expected better.
One other thing...ggee6688 mentioned that his light came on. I've never had a low fuel light come on! Do I even have one? My cluster IS the one without the tach, but the needle has been on "E" before, and I'd expect there would be a light. Think it's burned out?
