Personally, I would drain it and refill it with more Dex Cool. I'm pretty sure your current antifreeze has been in there for 5 years or 150,000 miles.
If you feel like switching to conventional antifreeze, you will have to drain and fill it every 2 years or 30,000 miles.
I don't like Honeywell's Prestone universal antifreeze. I personally use SellZone, Zerex, or Peak.
