Funny this thread came up, since I stopped using it then used it again before adding data to my app, since I got a new phone and forgot to online sync it then lost all the data, lol.
Figures so far (only a 50-60 mile commute the last few weeks)
All the figures came out the same on paper. Driving habits remained the same and I have a straightforward commute with little to no side stops or periods of idling. All regular gas (87) from chevron. Sometimes I go to Valero (couple times a month, as seen by the $0.10 cheaper fill ups). I only go to those two stations, same location even lol.
