Antifreeze VALVOLINE or OEM BMW

i have a 21 jetta, been using the valvoline one, no issues

I use Valvoline Zerex Asian Blue in mine. Good stuff, and compatible with OEM Mitsubishi coolant, for like half the price.

I used genuine bmw coolant as the price was around the same.

I personally prefer OEM, but I was at a Lexus dealership for 9 years that used Valvoline and never seen it cause an issue

BMW coolant is down right awesome stuff.

Flush your cooling system and replace the green coolant with Valvoline Zerex G48, it's what's inside BMW's coolant jugs at the dealer.

I used Valvoline Zerex Asian Blue Vehicle Antifreeze/Coolant in my 1st gen anytime I needed to drain the radiator because you can buy it anywhere. 50/50 is handy for top offs but if I was doing a full flush I got concentrated and mixed with distilled water which comes out a good bit cheaper.

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

So you don't mix coolants. BMW coolant uses embedded teflon or something. Dump in the wrong coolant and you have to run (I kid you not) laundry detergent through the entire system several times, flush the shit out of it several times then replace every single rubber hose.
