My E is starting to get broken in. I'm was at 3773 on the odometer this morning when I got to the office. I'm still getting right around 21 mpg in town, but on the highway (no A/C, 75-80 mph) I've been getting just under 26 mpg. If there's a good headwind (as there can be on the Snake River Plain in Idaho), it has been dropping down to 23-24ish.
My best tank of gas was on Highway 21, north of Boise, towards Idaho City and Lowman. It's a windy road, uphill, lots of ups and downs and curves, and top speed couldn't get much over 50, and I got 28 mpg. That was right after I got the E, and I haven't seen that mileage since...the stars must've been aligned just right, or I did more coasting down hills than I thought. :roll:
