There are some Jeep forums online where Mopar Orange (dyed G-05) got mixed with the purple in some of the early '13 Jeeps, sludge resulted.
The "new" MOPAR 10 year, 150,000 mile coolant is an OAT coolant sans 2-EHA,nitrite, phosphate, etc.. It's material standard number is MS 12106. When you google the ms number, you come up with numerous products that state that they meet this standard. Several labels indicate that it is suitable for light duty diesel engines only while other labels state their aftermarket product covers both light and heavy duty use
. The aftermarket products recommend 5 year/150,000 mile changes vs. MOPAR'S 10 year recommendation. Just sharing information.

I can't seem to find Prestone specs (someone help me), but I believe they have the MS 12106 label, at least the Dex Cool type.
racin4ds is correct that G-05 didn't hold up well in Ford diesels.
Regarding the original question, Rotella ELC
NF (nitrite free) says it is Dex Cool compatible, but I don't see the MOPAR spec listed. I would not use it under warranty (just how I am).

Interesting to me - these newest ELC coolants don't require additional SCA additions.
