I finally did what I thought couldn't be done. I got 62.0 mpg this morning, which included an extra 0.6 miles to McDonald's. Then the trip back...
139.4!
Averages out to 100.7 mpg
I week ago, I was getting around 65-75 mpg roundtrip, and 75 was tough! I'm taking a whole different approach, in which my max speed is under 30 mph. Today, I left the stoplight to begin my downhill desent, sped up to 17 mph and EOC the rest of the way. The hill took my speed to 28 mph, and that was exactly what was needed to never turn the engine back on.
