lol, both those links say mixing coolants doesn't matter so long as they are both similar "ingredients". My X was low enough that we could not tell what was in it. Looked green to me though. That said, we put in phosphate free green. It will be drained in all of about 8 weeks though. We had a nice thaw out today. Looking forward to more.
