I am using actual fill numbers. I understand it'll vary quite a bit, but it should all average out in time. I don't like the idea of using the MFD for tracking as it is not 100% accurate. When possible, I'm logging what the MFD said in the notes section. There were a couple fills when I wasn't tracking that, but I told my wife (who almost always fills it up) to start logging it.
I really haven't been driving the car a lot though. I only drove it one day last week. So, I haven't got to play with GPS too much. I did have a good commute in this morning according to the scangauge. However, its still not calibrated, so I can't say for sure what kind of mileage I'm getting. I just know that it is better than what I was getting before.
