I just think it's important that the advice we give is consistent with the manufacturers recommendation which brings me back to my original statement. Just because you can use a non certified coolant in your Mirage doesn't mean that you should. You have a lot of miles on yours and maybe it's not that critical of a issue in your situation. But I think it's important to qualify recommendations so people that are maybe not as mechanically inclined as you are to believe that coolant type is irrelevant.
