Hi Basjoos:

___Both the Corolla and the MDX are Auto’s, the Insight is a 5-speed of course. The MDX and Insight have game gauges. With their game gauges, I see as much as .5 mpg per hill when not using the DWL technique and I don’t get it all back on the downside. This continues until a lower overall average is achieved. With the DWL technique, fuel economy continues to climb up until a much higher overall fuel economy is reached. If I revert back in the X, the fuel economy begins to fall back towards that lower overall average I would achieve without this fuel saving technique. We are speaking of 3 entirely different types of automobiles + the Buick Le Sabre I drove on vacation throughout much of the Southwest a few weeks ago. The technique saves fuel in all 4 of these differing types of vehicles and I cannot see how it wouldn’t save fuel in your std. lean burn ICE equipped Civic. The fuel economy speaks for itself but that might be just be me as Eric Becky likes to point out

___As for messing with other drivers, Don’t. There isn’t always a driver behind you and you can do what you want when there isn’t. If there is, let them pass before you get to the hill otherwise don’t use the technique if it makes you feel uncomfortable.

___Good Luck
