I have just downloaded the European fuel prices for as I'm taking my A3 on holiday to Switzerland and Austria via France and Germany next week.
Just out of interest and to prove that we are paying too much in the UK, these are the Diesel / 95 petrol prices per litre:
France - 78p / 90p
Germany - 78p / 91p
Switzerland - 77p / 75p
Austria - 71p / 80p
Also note that in all the European countries Diesel is much cheaper / litre than 95 Lead free petrol.
