tranquility, the car learns based on your driving habits and slightly alters its performance based on those characteristics. Not saying it will make a big dent in your gas mileage but it's a good idea to reset the ECU once you feel comfortable so it doesn't remember how you had to drive during your break in period.

With the iDrive you can reset the milage computer for a journey or the total milage calculator through the iDrive options...

Over here we have these little thingies at gas stations:
What you do is you insert the nozzle into the tank of your car and pull the trigger, and in a minute or so you have a full tank again. Remember to repeat this often enough and you'll never have to worry about MPG again. |

One thing I've learned about these direct-injected, high strung engines is that they are very sensitive to a dirty air filter. On my IS350 I noticed a fuel mileage degradation once the air filter reached 8,000 miles/13,000 km or so, and changing it instantly restored the mpg. I would assume the N54 engine to be just as sensitive; these things need lots of air! Change or clean your air filter every 10k miles/16k km or so to preserve your fuel mileage and performance.

You were inferring older engines and their changed consumption. I played on older drivers instead... I found it funny, but then again, I am criminally insane...

I estimate 85% driving at 75 MPH / 120 KM/Hr and 15% at lower speeds in towns and cities. You will find that it starts to lower as you drive longer distances. In my case it went gradually to the lowest reading above after around 8,000 KM Hope this helps. UPDATE ... this was with my sDrive Z4 3.5is ... just to clarefy since I now drive an M3
