This is only a little off-topic... I was adding a bit of antifreeze to the wife's 97 Eclipse and noticed (for the first time...) that the antifreeze isn't the "normal" happy fluorescent green, but is a blue color!! Is this Dexcool? If it is, is there a problem with adding a little (maybe 1 cup) normal antifreeze to it? I hope not, I already did... Semper Maintenance!
