Congratulations! I'm not surprised that you did it. I routinely follow what you and Nash have posted on the database. Your recent numbers convinced me that you would be the first to do it.

You said that you normally suffer from freeway driving. My best tank (47 mpg), I had 80% freeway driving. I find that a long drive on the freeway followed by 4 or 5 miles on the surface streets will consistently net me 50+ mpg.
