Break In Oil
My brother has a new Patriot and was told that they do use a break in oil! I thought this was something that was done away with years ago. Has anyone else ever heard of this??
the break in oils that are made today are intended for the older engines with flat tappet camshafts. the zinc forms a shock buffer coating on the lobes. it is also very good at ruining cats and emmision systems of a modern car.

Just wanted to inquire about something as well, seeing as how JBTJ said to change at 1500 ... is that necessary?, i talked to my service tech at my dealer that i bought my 2013 Jk from and he said first oil change should be normal, around 5000km's. Just checking out of curiousity, as I'm just over 2000 km's. (not miles)
I read an article that Blackstone Laboratory tested oils and found that only Honda uses a break-in additive (molybdenum-disulfide) from the factory. The lab said to follow what the owners manual states for changes for the first change. It definitely can't hurt to change it early. I think the focus should be put more into actually breaking in the engine as stated in the owners manual. I'm sure very few people leaving the dealership even know about breaking in a new engine. My WRX is the only car it was mentioned to carefully break-in. Some will argue the oil should be changed to remove any metal particles, but the filter will catch the small amount avoiding any internal engine damage. It's an opinion thing so one should do what makes them feel good.
