I don’t think that’s true anymore with modern engines. It’s my understanding that the on / off strain is no longer a limiting factor on engine wear and that the emissions and fuel saving benefits may be mild but are real from a net efficiency standpoint. While emissions savings are probably the greatest, I’m using this primarily to save anything I can with wartime gas prices.
Newer engines use different starter motor technology to reduce starter motor wear and the oil channels are designed to retain oil in the engine where previously there would be a moment of low pressure which you could hear as a slight tinny sound before oil flow.
