I am surprised no one has really talked about the fuel saving, we have pretty good engine instrumentation om our RV7 including fuel flow indication, leaning properly in the cruise brings the fuel flow down by over 10L/hour, so by leaning properly you are not only being kinder to your engine but saving considerably on fuel - even if I am hiring wet I would rather have that fuel in the tank than not!
