Antifreeze PEAK or VALVOLINE

Since that 5/2023 bulletin refers to Valvoline as formulating the latest version of G12Evo, and Valvoline/Zerex HT-12 says on the bottle that it is for G12Evo applications as well as referencing VW TL 774-L, it should be okay to use HT-12 in our coolant systems.

I've used Peak OET Blue in both Hondas and a Toyota for years...last time I got it, was 17 a gallon

i use regular peak coolant, works fine

I use Valvoline's Zerex Asian Blue prediluted, it works just as well.

I run the Peak Final Charge Global red coolant. Less corrosive than the green stuff, and I haven’t had any issues running it.

i use peak 50/50 Red stuff formulated for toyota lexus and scion

Not an LS specifically but I had good luck with the PEAK 50/50 pre-diluted mix from Autozone.

I used peak when I changed my rad, no issues so far

I use Peak for Asian vehicles, green in color, for my Mazda's. Get it at most auto parts stores in 50/50 mix so you never worry about cold temps in winter.

Peak final charge is compatible and meets all necessary specs. Bonus is it's available almost everywhere in the US and Canada
