Antifreeze VALVOLINE or OEM BMW

Zerex G40 is pretty good. Made by Valvoline and has G12++ spec.

genuine BLUE BMW coolant (they released a GREEN BMW coolant around 2019 so remember to specify you want BLUE when ordering parts now). I dilute it 50/50 with distilled water (not tap water).

BMW blue only.

BMW only. Not saving yourself any money in the long run being cheap with this particular fluid. It isn\u2019t even that much more expensive than other brands.

OEM stuff from BMW.

Only use bmw brand it has special additives for the electric water pump

Only the OEM bmw blue coolant. Don\u2019t use anything else.

BMW coolant; it\u2019s cheapish, certified, and you should need it again unless a leak issue.

I went with Valvoline Xerex G40. BASF G40 is the equivalent of G12++. Valvoline/ZEREX G40 Euro Pink coolant meets this newest worldwide standard BASF G40 and German standard VW G12++ .

Brands I recommend are of course Toyota OEM Super Long Life coolant and surprisingly Walmart Asian Red Super Long Life coolant (actually comes out pink ) has never failed me and I offer that as an option to my customers. Then there is the Valvoline zerex Asian I don\u2019t highly recommend this coolant but it does work just not that well from my experience.
