Yeah that's a decent FE for a petrol car. What's surprising is the MID figures which is off by a good 20%. Looks like TATA did a Maruti there
. My car( Grand i10) doesn't even have a MID FE indicator and i depend on fuelio app for FE figures. FE figures of my car is very similar to yours..I see that you are also using Fuelio app, do you mind sharing the FE till date, you should see that in home screen under "Average fuel consumption". Mine shows 14.0 kmpl with total ODO reading of 9300 kms.
