It's not quite that epic. It starts out great for the first 8 miles, then I have to climb, but it's a mild climb that I can still eek out 26mpg at 65mph. After that I get into more traffic and fewer long opportunities, but still have some 1/4 mile to 1.3 mile stretches I can coast if the traffic is right. Friday was epic, with perhaps a 40mph tail wind on the way to work and it died down by the time I went home, so I managed 30.9mpg going home for a daily average of 41.6mpg. Usually my down mpg is around 55, my up is around 30mpg and I average 38mpg round trip.
This weekend was a real eye opener. My first really long drive since I started hypermiling with several very long descents. Brought the tank to a new record 40.6mpg and managed 47 outbound and 44mpg returning. Now I'm going to try to see if I can get my first 500 mile tank. At 13.2 gallons, the gods are going to have to shine down on me to make it, but I'm off to a great start and the weather looks like it should cooperate at least through Thursday (temps in the 50s and maybe even 60F!). A storm is coming in Friday, so I'll have to fuel up before that (I never drive on less than a quarter tank if a storm is coming). Then again, maybe I'll take the long way home to ensure I get in the miles.
