Hi Guys, my D40 is a 5/2010 ST-X 2.5 Diesel Auto and at the moment only has a ARB bar on it. my first long drive- on black top, i was getting over 800kms on the tank. At that time i was getting 9.9lt/100km. i was very happy with these figures. i am getting around 650kms/tank around town. not bad...
