The spreadsheet gives you an approximation of how much you can expect to save in fuel costs in a given year based on your annual mileage.

Simply change the prices of petrol and LPG to match what you would be paying and the spreadsheet will recalculate accordingly. If you are not sure of the price of LPG in your area then we suggest you use the price of 75 pence as a guide.
