Barry, I got 47.9 mpg with the Econ button on today! Yeah, there were a few slow drivers, but I am a tad bit of a leadfoot. I am so pleased getting such numbers. When I got gas on Thursday at my usual Citgo, I had 5 miles left on the Range and took 11.32 gallons for a tank that had 472.3 miles on it. That averaged 41,72 mpg. So, I guess Honda is accurate that the tank holds 13.2 gallons. Not bad for a car that will be 4 months old on Tuesday! I am so pleased with the car. Of course, I have not used the AC yet, and I am afraid what that will do to the mpg. I didn't use the AC much in my last HCH. My car just begs to go places! You dressed yours up pretty good!
