I tested my fluid with a Refractometer and it looked good my reading was -15@46% for propylene glycol. From what I can tell it is like new and I shined a light into the fill tank and saw nothing floating in the fluid. My fluid is green so Im assuming it is Century. I think Ill put this on my list of things the check annually. Thanks for your help.
