Motor Oil from factory?
 
Does anyone know what kind of motor oil there is in the 3.6L? I just drove from Seattle to Montana and back and I'm quickly closing in on the first oil change. I would prefer to go synthetic, but wanted to ask if anyone knew what they put in from factory. My dealer had no idea.

WTF? They had no Idea? Check the Owners Manual or the Oil Cap. It should say something.

im sure you can go either way. just once you do syn you can only fiil it up with it untill you empty it out and go back to mineral

It makes no difference if you use synthetic or mineral, as longas whatever you uses matches the specs in the owner's manual. You also can switch back and forth between the two or even use half synthetic and half mineral oil at the next change.

Not at all true! They are compatible with one another, even without using the same viscosity.

I highly doubt the factory fill is synthetic. I'd go with Pennzoil Platinum for your WK2. Great oil, readily available, and if you go to Wally World you can pick it up for ~$20 per 5 quart jug.

Yes. You can change between Synthetic Oil and Mineral. I did it a couple times with my WJ to make it run smoother. I tried Royal Purple and it ran very smooth. Then I just changed to Regular Mobile Clean 5000. It was Cheap and I did it every 2000-2500 miles and it ran fine also.

funny, I called the designated toll free number for GC2011 and guess what, they did not have the technical documentation at hand to tell me make, or min/syn, but they did dig up that it was 5W30, after 10 minutes:-). they will get back to me in 2-3 days. I know, I'm anal about oil choices. But just as I always put Mobil 1 in my fun car, I want to put the right thing in the GC.

I just came back from Walmart andI saw that they were selling 5 Quarts for $21 of Mobil 1! Once it's time for an oil change I'm doinng it myself! Last Oil Change I payed $104!

OK, so today, I got a message on my home voicemail form Jeep. The lady left a message saying that there is a "high quality synthetic oil from factory". She also claimed "mineral oil is not allowed in the car". Those were her exact words. I don't believe any of it, nor does the manual. I guess I will call tomorrow and inquire further.
