The prices here in the UK are awfull (compared to Greece for instance). There was a huge strike and blockade of the oil refineries a couple of years ago but the goverment didn't give in. We usually pay close to 1.25 USD per liter.
When I drive south of London towards the coast (where my girlfriend's parents live) I have to fuel my Lancia after the round trip, whereas with the Clio it takes three trips - talk about consumption.... The difference? The first one is 2.00 Liter Turbo, the other one is a 1.6 Liter Diesel...
