Driving Europe

O.k. I know with rising fuel prices etc this is going to be hard to predict, and obvisouly I don't have an complete route yet, but I was wondering if anyone had a vague idea how much money I would need just for fuel whilst driving around Europe. The rough plan would be driving from Oxfordshire, England, down to the coast, ferrying across to France, sights around France, to Germany, around Germany, Poland, Sweden, then Norway (probably ferrying) and Italy, Greece and Macedonia. Obviosuly probably not in that order as that will be all over the place but any esitmates very welcome. Hopefully going to be driving a Renult Senic or something similer.

Cheers

have googlemaps or some similar site/util calculate total distance, and then look into fuel prices as mentioned on websites of major oil companies. In most of Europe, there will be very little difference between those prices and what you eventually pay (although you have to add VAT and other surcharges, obviously).
