I noticed my coolant is low and i just wanna top it off. The light hasnt came on but i see that its low. My question is, is it okay to use PEAK Original Equipment Technology European Vehicles Blue Antifreeze 50/50 from auto zone

just use water and monitor for leaks

I've used Peak and Super Tech from Wal*Mart and they are fine.
But if it's just a little bit, less than a liter or so, topping off with distilled water is a good rec!

Unless you know what coolant is in the car now, i wouldn't use it. Mixing coolant brands is not recommended. Just use water to top up.

Never use tap water on top offs only distilled water! You don't want minerals in your cooling system. Additionally, ensure you have premixed concentrated coolant as adding just coolant can and will damage your entire cooling sys.

Destilled water should be OK to top it off.
