Drove my wife's Regal the last couple days running her to doctor, groceries, and other places, and notice the engine didn't auto-stop anywhere. For some reason, it has decided to behave like a normal car. Don't know what's up, but I like it. Only thing I can think of offhand is that oil says it is at 7% life. Would that keep it out of the stop/start mode? If so, I may just "forget" to reset the service interval when I change oil, and see if it keeps idling nicely.
