Inst Econ certainly gives you a feel for "excess" usage or economical usage. However, I find I just tend to drive the way it "feels right" to get me where I want to go and to hell with the mileage.  HAHA I wish I could say that... getting 13 mpg's doesnt let me... well my wallet wont let me at 13 mpg's 
I've been monitoring mileage using a spreadsheet. Over 5671 mostly highway miles of non-towing, I averaged 15.1 mpg. Towing my 3600# trailer over 3559 miles, I got 12.6 mpg.
