When test riding the new 2015 Rubicon with DCT I noticed there is no "Park" setting. When in DCT, do I have to put it in Neutral or can I leave it in Drive when shutting down?

When starting up….and in ESP mode….can I shut down and start up in 1st gear? I’m assuming that the ESP won’t let you start up anything other than 1st?

What grade oil is recommended for year around use?
