The rpms have to be extremely low to get into the very high mpg range.
Are you suggesting that what I am calling an occasional problem with my car is just me occasionally forgetting how to get good gas mileage? I travel this particular route probably 10 times a week and am quite familiar with it. Also, I have logged most of the 5300 miles that are on the car in my nearly 4 months of ownership. I have driven the route with the car enough to know when it is not acting properly.

I will try to explain this problem again.

During normal operation: I am cruising at 50mpg. By slowly letting pressure off of the accelerator, I can get the FE to increase to a variety of levels between 50 and 100mpg. If I keep letting off of the accelerator, the ICE will eventually shut off.
