In which situtation you consume less fuel? After all when in 5th gear, you accelerate in lower rpm. So?

Depends on the car and how you accelerate relative to the ideal for your car, but in my 98 Civic DX Coupe... I would chose fifth, which is at about 2000 rpm at 45mph, and at 75-80% engine load that would be better for mpg.
