Stephane,

My first post is to thank you for your post and summarizing information from various threads. Although our HCH II is my wife's car, I drive it when I go to the Bay Area for client matters. I found most of the techniques you specified in various threads and shared them with my wife. In short, they work! I may not get 70, 80 or 90 mpg but we are getting better mpg than when we first got the car. In fact, I think our lmpg is currently a little over 41 not counting the first fifty miles which was lost when we reset our trip odometer. I got almost 50 mpg on my last trip to the Bay Area (260 miles RT). I think the only other thing I've considered doing is increasing the PSI in the tires otherwise, we're pretty happy with the results we are getting. I think your post can only help, especially with newbies like us. Thanks again.

Roy
