I bought Tata Tiago 2025 top model petrol in feb 2025.

Drove 16000 kms+ Long drive, short drive daily commute.

All 3 services timely done. Oil changed

Tried everything, every suggestion got online/offline...

Using max gear/ very less clutch/dont race..

but...

in summer - city- 8-10kmpl,

Highway - 16-17kmpl at 80kmph and 15kmpl at 100+ kmph speed

in winter- city 10-12kmpl,

Highway- 17-18kmpl at 80kmph and 16 kmpl at 100+ kmph speed.

Any solution or suggest?? Any DIY?
