I'll probably get flamed but here goes. Interesting, but not surprising, more wear, but they want us to believe otherwise. I'd turn it off, every time I get into the car, or find some kind of flash, or plug in device that shuts it off all the time. Then the start stop system will benefit me by having some if not all of these features: A better battery, stronger alternator, stronger starter, upgrade bearings, maybe a few other tweaks, possibly better oil, etc. Then it becomes a win win 'for me'.
The EPA and CAFE are really pushing the automakers and oil companies harder and harder. Oh and lets not forget it adds to the cost of the vehicle. I'm glad for now I don't have it, and hope if/when I do it can still be turned off. Flame suit on.
