I live on the west coast of Florida where the elevation differences between the freeway and the parallel roads are basically the same. Given that, I find that it's always best to take the road that lets me cruise at 45-50 mph. My fuel consumption at 50mph in the heretical mode is usually about half (.5-.6gph) compared to cruising at the same speed while not in this mode. I takes me a little longer to get where I want to go but I never sit in traffic jams.

Some other things I do are:
1. Never use the cruise control ( I do better without it). Go fast down hill and slow uphill
2. Avoid using the A/C. I have the darkest window tint allowed in this state.
3. Only use the EV mode unless I'm positive I can recharge the battery i.e. coasting, braking, going down hill. The only time I use it for the sake of using it is during the last 2 miles of the trip.
4. Freeway speeds never greater than 65mph.
5. 87 octane Shell gas works for me. Since using Shell exclusively, I've never had a tank below 47mpg. There's alot of debate on this one.

I guess there's nothing very remarkable about my list. But I must say that the single best way to obtain high mileage is the 45-50mph "energy re-circulation mode". There is absolutely no way I could get this kind of mileage without it. It will almost double your mileage for any given segment of road.
