Driving (mostly) 55: results...

I blogged several weeks ago about my decision to drive 60 miles an hour.     In northern Wisconsin, where the actual speed limit is usually 55, I stick to 55.    On my last fill up, I was surprised to see the gas milage on my little blue 94 Prizm go up to 40 MPG.   That seems too good to be true, for a car that got around 30 mpg before I started paying attention.   Is this typical?   I will test the results again this week.  

I can't be preachy about what people should do to reduce their energy use-I put a lot of miles on my cars.    But I think everyone should do something, and I am just offering my experience with an energy saver that every driver could employ with little difficulty.
