The Post Office's annual Motoring on the Continent Report 2011 looked at the cost of fuel and accounted for exchange rates across Europe.
It's research found that for unleaded petrol the cost of a 1,000 mile journey in France was £234.43, in the UK it was £205.91.
Even the appeal of running a diesel car in France does not seem as strong, for a similar 1,000 mile journey it costs £206.13 on French roads, and £211.51 for the same trip in the UK.
The falling value of sterling has had a marked impact the Post Office survey of fuel costs in 14 countries found, with pump price rises in Europe even greater than in the UK.
Compared with last year, UK prices have increased less (11.5 per cent for unleaded petrol and 13.8 per cent for diesel) than in any of the other countries surveyed.
Cheapest for the second year running, fuel in Luxembourg costs £1.12 for a litre of diesel, although unleaded petrol costs 16p a litre more (£1.28).
Motorists will also get more bang for their bucks in Spain where fuel costs just 2p more than Luxembourg for unleaded petrol (1.30), but 9p extra for diesel (£1.21).
Sarah Munro, Post Office head of travel money said: "The high fuel price increases in Europe mean that UK holidaymakers should plan their routes carefully in advance to cut costs.
"For example, motorists driving through eastern France can save 27p a litre on unleaded petrol or 24p on diesel by detouring into Luxembourg."
