I just want to be another voice that would like to see this feature added to Fuelly. Fuel efficiency is nice, but total cost of ownership seems a bit more important in the long run. Tracking this added piece of data would also be helpful so we could see how oil changes and tune ups affect our mileage.
What I would really like to see is some type of call out on my recent fuel-ups graph that shows when I've done maintenance to my car. I'm imagining something similar to how
Google Finance shows news on a stock's market graph.
The advantage of this would be to easily explain why we might see a mileage bump in our driving.
