Fuel consumption spreadsheet

I uploaded this file by request from elsewhere, and I thought I'd post a link here too for anyone who can make use of it.  MS Excel format:

It's written for use from within Britain.  Just enter miles traveled, cost of fill up, and pump price per liter in columns B through D and the remaining fields will appear.   Obviously you need to start and end with a full tank for the figures to be meaningful.   Don't leave any blank rows as you progress down the sheet, otherwise the running average will be incorrect.

As originally uploaded for a mostly British audience it's set to work in Imperial gallons.  Just change the conversion figure in cell F1 to 3.785 if you want U.S. gallons.
