Hey thanks for the terrific replies. I will follow all your suggestions.

I should have clarified i live in surburbia and commute into Manhattan and do a third of the drive on local roads, 1/3 on the FDR which is a coasting 45-55 mph when I commute, and the final third in traffic. I've driven out to PA and also to Southern NJ - highway 90% of the way.

Let's see if we can make adjustments and get the next tank at better mpg.
