i always thought mopar and amsoil went hand in hand.

 

OEM ATF+4 is already synthetic.

 

Thats true but when I changed mine I went ahead and did RP in it just because........... LOL

 

So what all is synthetic oil in from the factory? Just the trans or are the diffs and motor oil also synthetic from the factory?

 

I use Amsoil, and wouldn't change to anything else. Be careful with RP a buddy has had problems in extreme cold temps. He witched to Amsoil and no problems

 

Front diff is dino oil. transfercase, transmission, rear diff are all Synthetic. Engine is dino oil.

This is how they come from the factory.
Flushing even Synthetic fluid out at 30kmi is never a bad thing. Just because Synthetic lasts longer doesn't mean that there aren't wear particulates circulating around inside the fluid.
Differentials are due at 30kmi as well as transfercase.
30kmi is a bit premature for the tranny, but nothing is better than Preventative mainenance!!!

 

one thing i did notice was that my transfercase fluid was green

 

Be careful who you recommend Amsoil to, it's fine in a diesel, fine in the older engines, but it's thickening agents that make it last so long is VERY BAD for an MDS Hemi engine.
There are documented cases of engine failures where 0w-30 oil was thicker than 20w-40 after 10k miles...

 

????? def should not be green.

 

I think the fluid in our Caliber CVT2 tranny is green It's also $27 a qt.!!!!

Never heard of green transfer case fluid. Not even the anti-freeze is green.
