Big mistake from many members. :uh Milege is maximised due to mixing kerosene in diesel. Burning Rate of Kerosene is longer than pure diesel. So if you have kerosen in your fuel tank,then MJD gives unbelivable milege figures like me 32.1 KM/Lt. : So please remove this funda from your mind that you are getting strong milege means your bunk is loyal. I have experienced many times, when my Turbo spins like a brand new car, my MJD did not give me more than 22 KM/Lt. When I face loss of power & poor drivability my MJD gives 25-28 KM/Lt on 4 way.
