Antifreeze Prestone or VALVOLINE
Prestone European Vehicles Antifreeze & Coolant states, Superior guaranteed protection - 5 years / 150,000 miles. Prestone Platinum All Vehicles Antifreeze & Coolant states, Extreme protection - 15+ years / 350,000 miles.
If you are going to use Prestone brand, then you'd want Violet color.
I run it in my 2010 Tundra. after much research and not wanting to spend the $$ on overpriced toyota branded coolant I swapped out the system when I hit 100k (Valvoline asian). That was maybe two years ago. 30k miles later no issues.
G12/13 has better lubricating properties over long periods of time, which is why they use it in what you always hear as "lifetime fill." This is due to the phosphates in the coolant.
The Prestone stuff works just fine and there shouldn't really be an issue.
There's Zerex (Valvoline) Asian car coolant (prediluted) that's made in 2 colors, blue and red, and it's supposed to be compatible
Call Valvoline (Zerex), which makes both green and Asian coolants. Most likely the green you bought is not like the green sold 20 years ago.
I have been using Prestone Green FORever, in all my cars but the one that is Dexi-cool. I don't think I have ever had an issue with the Green as I flush my cars on a bi-yearly kinda thing or when I have to change things.
From the manual: "The manufacturer recommends using MOPAR Antifreeze/Coolant 5 Year/100,000 Mile Formula HOAT (Hybrid Organic Additive Technology) or equivalent." Remember that the Routans are really Chryslers in disguise, so no need to go exotic brands on fluids. So you can try this: Valvoline Zerex ZXGO51 G-05 Antifreeze.
When I bought my Jetta it was filled with Prestone. One time the fan switch crapped out on me so while replacing it I did a coolant flush and decided to use G12. About 2 weeks later the car started overheating like mad.
