I noticed my over flow tank was almost empty and was wondering if I could use a long life all makes and models to top it off. I have a full gallon of napa all makes and models also a gallon of supertech all makes and models. Or should I drain all the old antifreeze out and fill with the napa stuff. The car has 60,000 miles on it now and I know Hyundai said its antifreeze is good for 120,000 miles. So if I change it now it seems to me to be a waste. So top it off or change it all what do u guys think.
Get the real OEM stuff, or "Asian import coolant"

The 2 coolants you have don't contain phosphates, and Hyundai uses them in their coolant.
I would also not mix other types of coolants with the OE fill. If just a bit low, I would normally add some distilled water to keep enough in the system.

I'm not quite sure, but I believe newer Hyundai come from factory with a LL coolant good for the 100K mile range (60K miles for older models). After the initial interval, OEM specs require changes at every 30K miles or 24-36 months.
