I know that there are programs out there on download.com but I don't think they have a place to record displayed MPG vs. calculated MPG. Thanks,
I thought the difference was important at first. Of course, you are entitled to your opinion. I stopped keeping track of the displayed MPG after four months. It was converging with the calculator result (PowerOne for Palm) anyway, and it made the refueling procedure too involved. I copy the calculator results into a Palm Memo and report it here and on GreenHybrid. Probably I'll stop (!) after about a year; I just want to see that mileage boost after 10K that everyone has mentioned.

You can quickly look up your MPG in the summary area. I use it for all my cars. Includes service interval reminders. It's really a great piece of software. Nate
