My current tank has 120 miles on it, and I'm at 57.3 on the gauge (which should be 59 calculated, based upon the error rate I've seen since new). I've been avoiding the short local weekend trips, driving a tad bit slower (57 average) and hopping in behind trucks (at a reasonable distance) when possible. Also, no or very limited A/C. All of this makes a big difference... but the car just seems to get higher MPG now vs. the same type of driving I was doing before. I can't imagine what is happening at 3,500 miles (to me or the car or to both), but it DOES make a difference. To everyone out there who has <3,500 and is disappointed with the MPG, be patient and you'll get your reward soon!

Once I get my HM star on the database, I intend to return to somewhat more "normal" driving (my wife is wondering why I never let her drive the car... why I'm a little "damp" when arriving home on a hot day... and why I use her car for the short trips during the weekend!!!). I suspect I'll ultimately settle in around 50 mpg. I'd be content with that!
