Today was the first true "highway" usage of my E300 to check the fuel economy. I made a round trip between Bryan, OH and South Bend, IN. on the Ohio and Indiana turnpikes. There was about 45 of 247.1 miles that was combined "city" and two lane state routes. I filled up this afternoon and calculated 29.1mpg. This this common? I was hoping that it might achieve closer to 32/33.
Thanks,
