Antifreeze Pentosin or OEM Mazda
I've used pentosin E for full flushes of two Golfs (2015 and 2017). No issues. Prior to that, I used it for topping off. It's the right stuf being G13 regardless of slight color variation pink/purple.
Pros: no issues, right stuff
Vehicle:
Volkswagen Golf
You're not supposed to add tap water... distilled water is fine for emergencies, but always top up with coolant whenever possible
Pros: distilled water for emergencies
Cons: not tap water
Vehicle:
Mazda
I’ve used Pentosin Pentofrost NF, it’s the same as OEM
Pros: same as OEM
Vehicle:
BMW
Use pentosin
I recently changed the coolant in my 2020 CX-5 with genuine Mazda prediluted FL22. The reason I change the coolant is corrosion protection. The corrosion inhibitors in coolant deplete with both time and mileage. Many aftermarket coolants may not be formulated with the identical corrosion protection chemical strategy found in the Mazda FL22 coolant. Using an aftermarket coolant is a risk I am not willing to take. My cooling system remains safe from corrosion. Using my schedule I will not have coolant and internal corrosion issues for as long as I own my car. Peace of mind is worth it to me.
Pros: corrosion protection, peace of mind

I've always used the Pentosin equivalent in all my Volkswagens and Audis. Pentosin E/SF. Pentosin SF is G12 (pink) -2005, Pentosin E is G13 (violet) 2006 onwards. Safe to mix with factory fill, of course can always go to the dealer for coolant too. These are concentrate, so you do have to mix 50/50 with distilled water though
Pros: safe to mix, reliable performance

Volkswagen Passat
If it's inconvenient to go to the dealer, you can buy the correct coolant at NAPA, they carry Pentosin brand chemicals.
Pros: correct coolant available
I had a bunch of Audi G11 kicking around from my Audi 100 that I used to have. Made by Pentosin, same smurf piss BMW used.
Put it in my e90 when I did the water pump.
Pros: same as BMW
Vehicle:
BMW
