Not exactly 'How to Win Friends and Influence People' at least not for our biggest two allies.

I had an Excel spreadsheet on here ages ago (which I still use) but I also found a free app for the Android - it's called "FuelLog". Seems to work pretty well, and comes up with the same answers as my spreadsheet.

Thanks, G. That could be useful to some.   
Here's the link to FuelLog.

I'm using "Gas Manager" on my iPhone and iPad. Works a great with great data either in charts or tables. Dud cost me a few dollars but worth it.  You can try it for free with limited entries. The app can record data for multiple vehicles and databases can be exported and imported using iCloud.
