Very impressed with our 2014 Grand Cherokee Overland with the 3.6 and 8 speed. Plenty of power, smooth as silk and great fuel economy. The 4x4 system is great and it has the adjustable air suspension too for clearance. Handles all the off road we need. I have my '78 CJ7 with 4" lift for any hardcore trails. * I use Mobil 1 EP 5w/30 in it. Great oil regardless of not having the Chrysler "spec". I'm sure it meets or exceeds it anyhow.
