Shifting below 3k and having WOT to get the revs up would actually chew more fuel.

As you said - stretch it out with small throttle so the motor has more momentum to keep spinning.

In saying that - I average between 400 - 500 k's per tank depending on driving style. And my fuel light doesnt work... lol
Efficiency is determined by fuel in vs energy out, not load and throttle position. Revving an engine higher is going to waste more energy through friction. Air pumping losses are minimised at full-throttle.

Accelerating and decelerating slowly, and maintaining momentum are key ideas to maximum fuel efficiency. When it comes to small capacity 4cyl engines however, sometimes keeping the revs down simply isn't an option, which fuels the illusion.

I get 500-600km from 50L.
