AoA. I have bought 2017 model Honda Civic few months back. Im maintaining it through 3S dealership. It has driven around 40000 km uptil now. Problem is its fuel average is dropping every month, from 10 it has dropped to 7. Im not a heavy footer and drives car smoothly with rpm between 1 and 2. I was wondering what could be the reason of constant dropping fuel average? Is it tyres or any engine issue? Needs expert opinions. Thank yoy
