You can read about oils and debates regarding them all day long.
One pretty good website is
I've used pretty much nothing buy synthetics (there are some exceptions, like on 23 y/o BMW motorcycles that tend not to be to oil tight) for the past decade or two.
Largely my decision to mostly use M1 was because of an experience I had with it while crewing for an SCCA pro-rallye team who tore the oil pan off their BMW M3 and ran it still bumping off the rev-limiter for another mile or two to get off the stage road, and seeing there was NO CRANKSHAFT or PISTON damage what-so-ever. Could that have happened with another oil, probably, but who cares, that was proof enough for me.
When it comes to Synths there is a LOT of misinformation out there.
And there is still some controversy whether you can change to it too soon or not.
As a matter of fact, I recently saw a letter from Subaru NA advising against changing to synth before AT LEAST the 1k mile break-in period. So I'm going to make the change on my new Baja at the 3k break-in oil change.
In the past on my Jeeps I made the switch at the first oil change as well, though YEARS ago I do recall waiting 10k miles on another vehicle.
It is true that many manufacturers even ship their vehicles with synth already in the crankcase, but since we don't know for sure what measures they take at the factory to prepare the motor for break-in (what type of machining methods are used, is it test/dyno run and how much etc) there is no way for us to make a blanket statement like:
You don't need to wait. Its not like it was in the 'good ol days'. Engines are so machined so precise that they are as broken in as they are going to get shortly after they are first run. You could run full synthetic in it as soon as you brought it home from the dealer.
That said, if Brandon has some specific info on the engine plant in question that may be true.
I'd also look at what Jeep says for the Compass maintenance schedule. If there is no first short term oil change, then perhaps he is absolutely correct and you can switch immediately.
Me, I guess I'm a little bit old school enough to wait for the first oil change.
Then again, it's PROBABLY much ado about nothing.
