There's at least few EU countries where Diesel is much more expensive than petrol at the moment. People like diesels because it's actually hard to get huge fuel consumption with those, while if you're not particularly careful any turbo petrol will drink fuel quickly. I had a 1.6dCi Qashqai and that car would not burn more than 10L/100km, no matter what I did or how aggressively I drove. Zero chance. I also have a 1.2TSI petrol Polo, and you can easily make it use 20L/100km if you drive it like a maniac - you have to be actively careful to keep it in the 6-7L/100km range, while the 1.6dCi would easily do 5L/100km without really thinking about it.

  Wow, I have a Seat with the same 1.2 engine and is really really hard for me to surpass the 8L/100. Maybe driving very fast can get you over these numbers but driving in the legal limit of most countries won't make you burn that much fuel!

    It has absolutely nothing to do with driving above the speed limit -as a matter of fact driving at a completely legal 120km/h won't use anywhere near as much fuel because you are travelling pretty fast and not accelerating anymore, so the consumption will be decent. But try accelerating from every stop in the city all the way to the redline, pedal to the floor, but never going above 50km/h - you would never go above the speed limit, but the tank would disappear in no time at all. I'm certain that if I tried I could burn the entire 50L tank of the Polo in ~250km, by just keeping it in high revs and accelerating hard(as hard as you can in a 90bhp Polo anyway) and frequently. The injectors will happily keep feeding the engine more and more fuel as you do this, while diesel common rail systems have almost a hard limit of how much fuel they can inject - no matter what you do you won't go above certain values.

      > not accelerating anymore maybe in a frictionless vacuum! At high speeds the force you have to exert to counter wind resistance is less than what you need to gently accelerate when going slowly.

    Agree with you on this. I had a Golf 1.4 TSI which I drove quickly and it was amazingly frugal.
