It took me almost 2 years to get these magical figures. At last all my hard work paid off and I can say that my car is probably the only Marina that gives such a g8 mileage. One more thing, there is no power lag below 2000 rpm i.e. even without turbo getting activated, during pickup it behaves like a petrol engine. Some more facts about mileage: During my visit from Rudraprayag to Kedarnath and back I got a mileage of 16.35 Kmpl at one of the most dangerous hilly roads in India(frequent landslides) and during my visit to Mana(the last village on Indian side on India China border, if I would have done another 45 kms I would have reached China) and dangerous roads via Nandprayag(including one of the most steepest hilly roads between Govindghat and Badrinath where you have to take your car up at first gear, with water from waterfalls overflowing on the road, thereby your tyres almost 30% submerged in water) and back I got a mileage of around 13.52 kmpl.
Tips:
Get all the genuine parts for your diesel pump.
Only visit a mechanic who along with engine work also knows how to do setting of diesel pump.
Keep the tyre pressure at 35 psi.
Use engine treatment during oil change(drastically reduces friction and engine overheating)
