I use Prestone 50/50 HOAT compatible in my 2012 JK and it works great. I like to do it every 3 yrs or so.
Pros: works great

Prestone Max Violet is ok to use--it meets G12++ or TL774G which is fine to use with the G12evo in your car already.
Pros: ok to use, meets G12++
Cons: only available in RTU
I always use Prestone concentrate and then dilute it down to a 40/60 coolant to water ratio.
Pros: good corrosion inhibitor
Prestone is designed to be compatible with the Toyota Red coolant, which is also POAT. Should be fine.
Pros: designed compatible, POAT type

Pros: no issues, long-lasting
Vehicle:

Mileage: 65000 km
I’ve done it with my fiesta that had a leaking thermal housing I think I ended up topping it up so much by the end it was almost all Prestone wouldn’t personally do it on a car I care about though
Cons: not for valued cars
Vehicle:
Ford Fiesta
that prestone that says it can be mixed with any type of coolant can do just that. You can mix it with pretty much anything and it won't cause a problem. The industry is well aware that if you mix certain types of coolants, you will end up with a sludge so they make this prestone stuff too be compatible with everything. Now, just because it's compatible, doesn't mean it will last as long as some of the other coolants when they are 100% the exact coolant.
Pros: mixes with any coolant, compatible
Cons: not as long-lasting
my buddy put the Preston stuff in his v6 cause you can mix with all colors and hes been fine for 6 months now not an issue.
Pros: mixes with all colors, no issues
I topped mine off with prestone platinum. Meets Ford spec and has been fine
Pros: meets Ford spec, been fine
