Good Car but low mileage

Pros: Driving is smooth and comfortable. Cons: The mileage in DCT after riding 500 kilometres in moderated traffic is 10 km/litre which is very bad and maybe after the first service should look in. In the initial period, it is only 8km/litre. I should spend around 10000 rupees per month, instead of this EV would be a better option.
