Modern Vespa

I know there are tons of hotly debated threads but a lot of what's said is very back and forth and I am basically just asking, as cleanly as possible, can I top off with this coolant: https://www.autozone.com/antifreeze-radiator-additives-and-windshield-wash-fluid/antifreeze-coolant/p/peak-oet-antifreeze-and-coolant-european-vehicles-pink-50-50-premixed-5-year-150k-mile-protection-1-gallon/720589_0?rrec=true

Thank you.

how far down is it? if it's just a little, then I'd top it up with distilled.

Just at the low line. I do always have distilled (thanks, sleep apnea).

That coolant is fine but distilled water is a lot easier to find, for topping it up.
