Hello! This is my first post on this site too, but I am on some other Jeep sites as well.
I have had my new Jeep (Commando Green Oscar Mike Freedom Edition 2 door)for a month and have put 1,500 miles on it. I love that Jeep, it's the most fun vehicle I've owned and I've owned a bunch, new and old.
From reading on other sites everyone recommends changing the oil pretty soon after purchase so I just did mine. It was very easy to do, I like the top-mounted oil filter. I suggest getting a torque wrench for tightening the oil filter cap, it's plastic and I was worried about tightening too much and breaking it.
That's all I've done to mine so far except drive it.
