Petrol in Ireland is 120.7 cent a litre... (which, roughly converted is about $7.15 a US gallon). But, that being said, people don't find the petrol inherently expensive here. The reason for this is not so much how much the petrol costs a litre, but rather how many kilometres we get to the litre – we don't drive around in cars with 9 litre V10 engines!!! We drive sensible cars. The price of petrol should therefore become less relevant to Americans, as they cop on to themselves and buy more efficient cars. The Citroën C2 that I have does 70mpg! Try getting worked up putting 40 euro worth into the tank every 2.5 months – it's impossible!
