I have been driving as econimacal as i can lately to see what range i can get from my 2003 TDCi 115. My light came on at 525 miles, so i will probably get 550 out of it. I filled the tank to the neck, but do the manufactures take a full tank as when it hits the full mark on the gauge or if you fill it till no more will go in?
I used to get 470 miles approx when i used to drive it harder, but i cover longer distances now and drive smoother. So what would my mpg be now?
