Specs 9555 23,MS, MSFCA needs to do a better job of referencing this properly from the owner's manual My manual calls out Mopar 10 years or 150,000 miles OAT coolant which is correct but also references MS, which is not listed anywhere on this container or any other Mopar coolant container that I could find Instead, this container lists MS27/1/21 georgef said Unfortunately MS coolant does not seem to exist (at least in the USA) If you go to a Jeep parts department they will sell you MS for your Jeep, it is also an OAT coolant There are those who say that MS is identical to DEXCool, but I haven't found conclusive proof of that If you want to do some reading on this
