Car in question is a 2020 Hyundai Tucson with the factory dark green coolant. Noticed that the coolant is just below the low mark when refilling washer fluid. I've got a jug of Prestone All Vehicles (not Platinum or Max, just the basic kind) kicking around and was thinking of using that to top off. The Prestone website says it's fine to use in my car, but I'd rather consult people here first, since I'm not all that knowledgeable on coolants.
Is Prestone All Vehicles okay to use for top up in my Tucson?

I prefer to use a coolant without 2EHA, but did a flush and fill using O'Reilly's store brand coolant in my 2012 Santa Fe. It was perfectly fine. Did a drain/fill every 30k for 200,000 miles afterwards. no problems. In the Kia I used an Asian vehicle by Peak (no 2EHA.)

I think it'd be just fine for a top off. Opinions will vary though.
I'm converting everything I have over to Prestone All Makes as they need coolant changes/work.

I used it in my Honda and it didn't seem to make any difference. I have since switched over to the correct formula. I wouldn't worry about it.
It’s fine to use in your car. 2EHA will mix with anything.
Prestone also makes a green coolant for use in Hyundai’s. It contains 2EHA.
I don’t think Hyundai/Kia even knows what coolant their vehicles need
our Carnival takes the Kia pink coolant. Kia will sell you prediluted and full strength pink, one of which contains 2eha and one that doesn’t, according to the internet 
the manual just calls for “ethylene glycol based coolant”… so, anything really.The world is going to 2EHA, good for 15 years at least. Coolant changes will become a thing of the past for original car owners. We just need to line up all the grandpas and let them know. Flame suit on!

Use the correct color Zerex Asian for your Hyundai. Recochem OEM in the correct color is also good.
Are you still under warranty? Coolant loss could be due to something covered by the warranty
