Edit: That's not a snarky reply - it's to show you how you can search this forum, specifically, using Google. It works very well.

I think most engines are pretty much broken in these days, but I haven't read up on it recently. OldGuy is right though, there's a lot of information to read about properly breaking in an engine, and you can search for it easily. None of the engine options available for the JL are new engines, so you can definitely find info on breaking them in.

Keep it under 3500 rpm for the first 100-200 miles, stay off the highway (high rev, constant speed), vary your speed deliberately during break in, do an early first oil change.

They describe the break-in period in the owners manual
