Ok, let us start by going through your first 2 miles. A blow by blow of turn the key, move, speed limits to first stop light including up or down terrain, re-accel to second sign/light and what speed limits including up and down terrain, third and what speed limits including up and down terrain. Cold starts suck but not that bad in the summer. City driving is where we receive the best FE. Hard to believe but it is a fact unless you hit every light at every block from first ignition to arrival.
___Anyway, let me know what the first 2 miles of your daily grind is like with as much detail as you can possibly remember and I will try and help you however I can? Stop lights and signs at the bottom of hills are really hard on the segment FE as well
