No passengers and aircond was off. Now I wonder how the claimed 21km/l would be possible
Add: The meter showed a supposed 20.5km/l

Thats the problem with 67hp pulling 800+kg. When you add in another 200+kg, the power weight ratio diminishes drastically and engine really has to work overtime, summore in start stop traffic.

Thats why I recommend any buyers who regularly fetch passengers in city drives to consider the Myvi over the new Axia if they not prioritise handling.

Btw, Shell FC sucks nowdays across all my cars.
