I've been quite an avid fuel tracker for years and have gotten a bit fancy with doing it through a spreadsheet in recent years (https://docs.google.com/spreadsheets...it?usp=sharing). I really like the 'conditional colour formatting' option. Can very quickly see where good/bad ratings are.
Eventually, I'll get around to adding my past vehicles as well.
I'm hoping to get Fuelly looking into connecting with Zapier. Then I can really automate the transfer of data between services, this would greatly help with my taxes for business purposes!
Anyhoo, I am impressed with the fact that my car will get stupidly good mileage(http://i.imgur.com/E7e2GGY.png) that just blows me away. Of course, I can't always do 5hr trips on secondary highways
Looking forward to see what I can learn to do even better!
