Hi Ron, I have a 2009 Mazdaspeed3 Sport, and I'm amazed at your results. If you posted those kind of numbers on any of the Mazda websites, people would think that your turbocharger had blown. In general with these cars, a sharp increase in mpg is seen as an ominous sign, ha ha. What sort of terrain are you driving, and how long is your commute? I have been trying some of the things you said before, shifting below 2600 (and below 2000 when I can.) Driving behind trucks, at a safe distance, at 60mph. My last tank I got about 24mpg over the tank, which was an improvement. Normally I was getting 22 mpg. This tank I've been pretty consistent in trying hypermiling techniques, so I'm very interested in seeing what will happen. I'll be very happy to get to the high 20's. I never had a fast car, and always wanted one. It's kind of funny, before I had a slower car that I wished was faster, and now that I have a fast car, I've become very interested in driving it slow.
