Nissna Micra 2019 heavy steering wheel and fuel economy not as good as expected.

[danny96l]

Hi I just bought a used nissan micra 2019 sv. It has gasoline 1.6l engine with 4-automatic transmission. I noticed that the steering wheel is heavier than other cars (kia-forte for example) and its not fully returning to the center on low speeds. Also I drive 70%city and 30% highway but I am getting 8,7/100km on avg (reseted when I bought the car). I don't do sudden acceleration nor brakes. I was wondering if these are normal for micras or if its just mine with issue. Thanks
