I have a used JK that I bought a couple weeks ago from a Jeep dealership certified. The antifreeze appears to be the pink/red "5 year" stuff from Mopar (don't think it's Dexicool at least). Is this what they're putting in now? I have a bottle of traditional Prestone around as well as some Mopar (3 year). Is the 5 year/pink compatible with Prestone and with the Mopar 3 year/green? I know Dexicool is not, but have no experience with the "5 year" stuff. I hadn't even heard of all of this different stuff until recently, so I'm not sure what is compatible with what, aside from the fact that Dexicool is supposedly compatible with only itself. What about this other stuff?
