Okay, now we're talking. My wife and I went for a cruise down the california coast to Laguna Beach. It was mainly freeway,with a little state highway and in-town driving. This time I kept to 60-65mph rather than 70-75mph and I used cruise control for most of it. Average MPG over 140 miles was 51.7! Outdoor temps were in the eighties.

Very pleased, but still wondering about these seemingly unattainable "city" numbers.
