I always use Prestone concentrate and then dilute it down to a 40/60 coolant to water ratio.
Pros: good corrosion inhibitor

Valvolines is cross compatable
Pros: cross compatible
coolant is always best. I would get rid of the green coolant, flush it all out and replace with something better. I use Peak Final Charge in everything.
Pros: always best, better performance
I'm running Honda type 2 coolant in my 94 sonoma. Flushing helped but it seems getting a good P-HOAT coolant stopped or at least paused the rusting while offering better protection.
Pros: stopped rusting, better protection
Ive been using peak for a while across a 2016 jetta when i owned it and now in my 2021 tiguan. Works fine
Pros: works fine
Vehicle:
Volkswagen Tiguan
Pentosin is one of my trusted brands. I would not hesitate to use it.
Pros: trusted brand
Get the Mitsubishi oem coolant. It’s more expensive but it’s better for the car.
Pros: better for car
Cons: more expensive
Vehicle:
Mitsubishi Lancer
Had good luck with their older Asian green, Toyota pink, and Newer Asian Blue in my son's Subaru.
Pros: reliable performance
Vehicle:
Subaru
I have topped of Supercoolant ( OEM ) twice over the course of 60k miles / 3 years ownership. Losing the factory coolant slowly over time is actually a thing. Since I have done the 2nd top off on the OBW it is now maintaining for over 6 months.
Pros: maintaining for 6 months
Cons: losing coolant slowly
Vehicle:
Subaru Outback
Mileage: 60000 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
