What oil is everyone running in their 3.8 I've heard that 5w30 was better to run over the recommended 5w20.
I've been running 5w-30 when I hit 70k miles, now at 136+ and no issues.
I've heard that there is a difference in oil consumption did your jk burn less when you made the switch

The 3.8 liter V6 was originally designed to have 5W30 in it when it was put in the Grand Caravan originally. I believe that Mopar due the cafe standards has had to knock it down to 5 w20 to help try and get the fuel economy up it does lead to higher oil consumption running a lighter viscosity due to burn off. I've run anywhere from 15w40 to 0w20 in my 2010 when I had it. Obviously the heavier the weight oil the quieter the engine runs with less top end valve noise. I would encourage running 5w30
