I don't see much difference for myself on the city MPG cycle but, my hwy MPG is better/more consistant as I am traveling more at the posted speed limit and not much over, while locking on the CC.
You can get better MPG by NOT using the cruise control under most conditions, because with most cruise control systems they apply too much throttle going up hills in order to maintain the set speed. If you maintain your speed with your foot, you can ease off on the accelerator a little bit when going up hills, sure you'll slow down a little bit but then you can get back up to speed on the other side when coming down the hill. Also, when not using the cruise control you can coast more often as well, and that's when you'll really see your gas mileage jump. That's why I love my Scangauge II, it has allowed me to adjust my driving habits in order to get better MPG in my Civic for sure. I don't even use the CC anymore because it bothered me how easily my automatic trans would be forced into a 5-4 downshift on even slight hills on the highway, where without the CC it will usually stay in 5th gear. And the instant MPG on the Scangauge shows a huge drop in MPG whenever the trans makes a downshift like that.
