I have a small issue with the efficiency log for "Baa".
1998 Mazda 323 Astina Gas Mileage (Baa) - EcoModder.com
After I added a fuel log entry yesterday (14.7.12), the 90-day fuel economy figure hasn't changed, it remains the same as previous (39.15). I don't think that's right.
This means that the % over EPA also hasn't changed of course.
The lifetime average and the 3 tank average have both improved as expected. The usage graph updated today and shows the latest entry as normal.
I hope it's not just that my calculations are that far off.
Pete.
