Hey Guys, i have recently bought the i20 sportz on 21st Oct-2013. About the mileage i am little confused with it, as when i bought it i heard initially we get less mileage and after 1st service and then 2nd it gradully increases and then get stable after second service. I have already covered my 2500Kms in one month. In very begining i got 9Kmpl in city but i never took it to highways for around first 200Kms. Later i took it on highway and surprisingly i got the avg of 18.2Kmpl(with 100%AC). which amazed me and made me happy that i have not chosen the swift instead of i20 jsut because of avg. After my first service done at around 2000kms, i found that my avg has been decreased, is this normal or do i need to get it checked with service center and get it tuned back to its original tuning. P.S : Car is just baught so engine is VTVT 1.2L sportz model. Plz suggest with ur comments.
