I have recently purchased a Jeep Rubicon ('05) with the 4.0L inline 6 engine.
Driving conditions...
daily commute to work 30 minutes, maybe 4 stop lights but mostly moving.
I do regular long trips of 3 hours plus 2 - 3 times a month
and
I do go out wheelin' (4x4)
The service manager for the Dealership suggested I stick with the recommended 5w-30 wieght of oil because Jeep (Chrysler) found that the heavier oils were causing premature end of life for many engines. But the service manager couldnt/wouldnt recommend a brand of oil. Any thoughts on oil filters are also welcomed.
