Just sharing my engine temp log from a newly changed thermostats( both engine thermostat and transmission thermostat) created by bmwhat app. Its a city commute with one uphill and downhill.You can see temp dropped little in the middle of graph while driving downhill.

Nicely done! Looks perfect to my eyes. I saw where you had made a comment over on bimmerfest that your mileage has improved as well. Good job!

Yes it improved my X5's fuel economy.Now it feels like we were just wasting fuel by running it cool.I am surprised that only a difference of 10-15 deg C in temp can effect fuel consumption.May be DDE is programmed like that to inject extra fuel until 75 deg C.
