^ I'm familiar with that idea, that starting the engine (mainly cold starts) is the most stressful. But my hunch is that it's an out-dated concept, and also not wholly applicable to the Insight autostop scenarios. I'm thinking it was more relevant 'back in the day' when engine oil wasn't as technically advanced, for one thing. Today engine oils probably provide more protection on cold starts, they probably coat engine parts better and stay there better than they used to. Add to this that the Insight has very 'light' oil and not very much of it to get circulating. And then, autostop happens only when the engine is warmed-up, so there's very little time for the oil to 'drip off' of the engine parts, so they remain protected... I doubt autostop poses any extra wear, or if there is any, it would be barely detectable. I've had engine oil analyses a few times on a car with about 240k miles, and the analyses have never shown undue wear. Not much to go on, but at least they don't show some glaring signs of wear... There's a good number of Insights around here with very high mileage - like over 300k miles. So, I really doubt autostop causing extra wear is something to be concerned about.
