Reviews of OEM BMW antifreeze

I’m running 110k miles in my M40 X3. There was a coolant issue but other than that it’s been an excellent engine.

330i, coolant repairs.

I use BMW coolant cause it's similar in price, so why not. Actuall,y a little cheaper cause my dealer does discounts

By “air intake reservoir tank”, I assume you mean it’s the coolant tank for the water-air charge cooler. We need to know what car to tell if the coolant is suitable. That “G30” on the front is the important bit.

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

BMW coolant is down right awesome stuff.

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.

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.
