I have a 2006 tata indica turbo which has clocked 2.25 lack kms
.i have been getting a constant mileage of 13kmpl even by varying driving styles.
For this reason i got the engine overhauled at tata ass
at 2lack kms along with the fuel pump,turbo and injectors.the car is regularly serviced and in very good condition.
but the tricky part .in mangalore we have a 60 kms 4 lane highway from mangalore to manipal ,by maintaining 85kmph at 2k rpm i got 30kmpl.I at first didnt believe it but after a lot of drives by me and my amused friends i keep getting the same efficiency of 30kmpl on that road .but when i drive on any usual two lane highway i get 13kmpl .i measure fuel efficiency by making my tank full and then after driving for 60 to 70 kms again refill it.I have tried everything ,but knowing my car is capable of giving 30kmpl on staraight road ,i dont get why i cant even get 18-20kmpl on normal roads.i have got 185 tyres over the stock 165mm and i drive with ac always
