I'll be able to provide some good data after my trip :-) It will be mostly motorways for me. It will be interesting to compare the estimate to the actuals after.
If we work on the following assumption:
63 litres in a tank or 13.86 gallons (not an assumption)
400 miles per tank (should be higher according to Sedici, but lets stay conservative)
gives us approx 29 mpg......
I'll overestimate the miles required (google says 3200 miles):
3600 miles in total for the trip
divided by 29 =
124 gallons required for the trip
Lets assume that the price of petrol is pretty much the same everywhere in europe and say £1 a litre or £4.50 a gallon
That means...... we will have to spend £558
I should probably allow for petrol costing a little bit more - lets say £1.10 a litre or £5 a gallon that comes out as £620.....
Of course all of this bean counting wont count for fccuk all if i end up having to repair the Coupe on the journey, but this wont happen...... <touches nearest piece of wood>
