As I'm writing this, I'm at the dealeship looking to upgrade my RAM (long story) and they have the '13 Superbee (yeah its tempting...) and I noticed that it has purple antifreeze. Anyone know what that is all about? Meaning did SRT change the antifreeze for all SRTs or is it the same deal like when they switched from Mobil 1 to Penzoil for whatever reason. Mostly the reason why I want to know is cause I do have Killer Glass radiator hose....
