Hey @salim001,
I've updated the first comment with the details for 3rd refuel as well.
The mileage is surprisingly gone upto 13.1 kmpl for last 380 kilometers. Out of which 75 km are on motorway. which is pretty nice for a 1.5 Aspire Prosmatec
Details duplicated from first comment:

3rd refuel = 29 litres = 2300rs @ 79 Rs. per litre
Meaning, 595km MINUS 215 KM (total speed meter reading at time of 2nd refuel)= 380 KM travelled in 29 litres till point of 3rd refuel.
Hence Mileage before 3rd refuel = 13.1 KMPL
i.e. [ 595-215 = 380km travelled in 29 litres = .. 380/29 = 13.1 kmpl ][/I]
