No I don't put mine in neutral... would only be extra wear/tear on the tranny (maybe not much) taking it in and out of gear. When you put it in neutral, you can hear the DCT coming out of gear (which means there is mechanical action in the transmission somewhere) and that, to me, would likely cause more issues long term than simply leaving it as is. I'm not an expert though so maybe I'm wrong.

When the car comes to a stop, the clutch is not engaged anyway (i.e. like having the clutch depressed on a 6MT) so I don't see how that saves gas vs. neutral. You are effectively in neutral but, again, I'm no expert.
