Greetings all. I wanted to bring up the topic of the purple colored 10 year/150K mile Mopar engine coolant that FCA has been using since about 2013 and possible aftermarket alternatives to it. For the most part, I have been under the impression that this is more or less a unique formulation that doesn't have an equivalent made by another brand. Recently however, I discovered some products by Zerex and Peak that are starting to appear on the shelves at many chain auto part stores. Zerex G30 is marketed as a European car OAT formulation and the product information sheet states that it meets the Fiat Chrysler spec. MS-12106, as shown on the Mopar Coolant label. Also, Peak has their "Pink" European Car formulation that they claim works in all 1995-present Fiat vehicles. Both of these are silicate free OAT coolants. From what little info I can find online, the Mopar coolant is a silicate free and phosphate free OAT coolant. I realize I am probably opening a big can of worms, but I was curious if anyone here has any insight into whether or not these are appropriate substitutes for the Mopar coolant. Of course, the obvious answer is to stick to the Mopar coolant to avoid issues, but if needed in a pinch, the Mopar coolant can be hard to obtain, since it is only available from a dealer or online.
