While it saves engine hours, I'm not convinced it saves much on engine wear, no more than it does on the fuel. There are those who argue, including manufacturers, that a better gauge of engine life is fuel used rather than hours. However, hours is easier to know so they've chosen hours as a convenient means. While saving hours impacts your service intervals, likely not extending your engine life much. Running the engine at 1000 rpm is very little wear on it.
