So coasting in neutral uses more fuel than leaving it in gear...

Happy 4th everyone!

On steep downhill grades, engine drag slows you down, neutral still helps. Although, it is illegal to coast in N....

OK...so worst is about 15MPG driving around town/traffic and for fun. Best so far was 24.7 and that was on a stretch of highway, WITH the M button on. I think since the throttle is touchier that you don't flux the pedal as much and it keeps the car at a steady speed. I also was doing around 70-75 the whole time which I think is optimum for the long legged M...I am doing a very long trip to Chicago soon and will report back on this in a few weeks...MD - Chicago!
