Hello , I recently upgraded to Civic X 1.8 2017 from Honda civic rebirth.
I am facing a poor mileage issue as average fuel average that i am receiving in city is 6.5-7.0 kmpl. I have done multiple things including complete tuning , throttle body ,cat cleaning , plugs etc. 2 times, one from local mechanic and 1 from Honda neither of them worked. Got the Gear oil changed as well CVT+ i guess, recommended by genuine Honda.
I have tried all these but all in vain, Honda says they don't take responsibility for the mileage.
What could be the issue
