Sure, everything has a spec and MOPAR isn't an oil company, but, if a vehicle manufacturer's team of engineers say I must use NV245 in the transfer case of the vehicle they themselves designed, I am certainly going to listen to them. It's up to AMSOIL to prove to me that they meet MOPAR's specifications. They haven't proven that, so I will not use it. I'm not being argumentative, I'm just stating the facts.
Here is the response I got back from Mobil Oil ....
No, Mobil does not have a suitable product for your application.

> I am in need of replacement fluid for the transfer case in my 2006 Jeep Grand Cherokee Limited w/ 5.7 and QuadraDrive II. I've searched your website and can't seem to find anything compatible. The Jeep owner's manual specifies NV245 fluid for the transfer case. Can you offer any Mobil products that would be compatible with this?
