My driving hasnt changed apart from , holding a motor at 2500rpm is holding a motor at 2500rpm I use cruise control , the log book shows the diference. I bet you have never tried one .(Hiclone) even if you con someoneelse to buy it like I did, see for yourself , before you trash it. I like the way you compare it to the American Dairy Association, I never trusted Americans that much either.
