Last week I filled up the tank ( 2nd fill) V-power shell, with only the last 1/4 tank I filled up 32 litres (guessing the fuel needle it's not accurate cause every 1/4 tank should be 12.5 litres) .
Anyways i'm shifting gears shortly (sometimes I guide myself with G-on blinking arrow up) and damn I'm keeping rpms stable below 3k I thought it would be better to keep rpms constant to achieve better fuel economy. But you're saying :

AFAIK new cars are factory tuned not to have a break in period like old cars where mechnical parts had to be in motion to achieve a better consistency and settle up. Hows the deal here, I do really more insight on this cause this car has D4-S port and direct injectors 2 which work at different revolutions, would be wise to know as to know when they kick up or not.
Right so here's my advice, some will disagree and you may remember this from the last time I responded to you asking this question.

You're trying to judge the fuel economy of a car based on one tank of gas you haven't even finished yet. That's like trying to judge how long a cell phone/laptop battery lasts based on one hour of use without accounting for talking time, web browsing time, video watching time etc.

I've said it a few times and I'll say it again: If you are driving stop and go then you WILL get the numbers you are describing, especially when the car isn't broken in.

There is a book in your car that details the manufacturer recommended break in procedure. It's fine if you disagree with Toyota, many people do, but it is generally accepted that fuel economy improves after the car is 'broken in'.

Get through two whole tanks of gas (needle to at least the 1/4 mark, if not further) and record the mileage at each fillup (you should have 3 mileage recordings) and then come back. Until then I'd say what you're describing is normal.
