I have switched to Liqui Moly KSF12+ Antifreeze. Learnt my lesson. There is no milkshake oil/coolant now, no overheating, but still idles rough.
Owner reviews for antifreeze
mixing ANYTHING with dexcool is a bad idea. Sister has a Chevy Malibu, takes dexcool, was low, boyfriend put in universal, an her car over heated. Told her to take to closest shop and have them flush and fill with dexcool. Hasn’t had any problems since. Do not recommend putting anything other than dexcool into a dexcool system
Ordered Subaru super coolant. Filled it half way between the low and the full line. That was a month ago. It stayed there and no more weird smell since. So no leaks.
I use the Prestone 50/50 Prediluted coolant which states “guaranteed for all vehicles American/Asian/European” on the label. It is yellow/green. Zero issues because it matches the specs in the manual.
Reputable brand blue coolant. Either bmw or at my shop we use Rowe
I use Prestone teal European car formula. No problems yet
50/50 Peak blue. Everyone says BMW brand but not everyone has a bmw dealership near them nor what’s to pay out the ass for coolant. I’ve had BMW’s for 23 years and they run perfectly in many ways. All I ever used was Peak 50/50 Blue
OE BMW coolant should be your first choice, and if it can’t be, second would be another reputable coolant maker that offers a European vehicle variant. For example, Prestone makes a blue in color variant formulated for use in euro cars. I’ve used both, never had an issue with either.
You can add distilled water as a temporary option if you can't find Toyota pink coolant.
Prestone destroyed my passats Cooling system, everything just deteriorated, the hoses in my car started to break up. I don't recommend prestone
