Is it normal for the fuel consumption of the Cetus to start at 23L/100km and then gradually decrease to around 7L/100km after driving a few kilometers?

That's normal, it's always like this when you first start. In the city, it’s around 5-7, which I find very satisfying with my [I Want to Be Quiet].

My premium model starts with a fuel consumption of 12 liters, but after driving less than a kilometer, it drops to 4.7 liters. Usually, the fuel consumption in the city is 5 liters.

It's normal. When it's cold, some drivers start with fuel consumption over 40. After driving for a kilometer, it goes down.

When I start, the fuel consumption is 39.9. Looking at this thing is useless.

That's normal. All fuel cars are like this.

Does your car also consume around 20 liters of fuel at startup?
