Owner reviews for antifreeze

I use comma g48 in mine. Compatible with BMW coolant and seems to work fine and is a decent price if you buy it neat.

I used the Ford coolant and haven't had a problem for the 2k miles I've done with it.

At the time I filled the system with 60/40 mix of Castrol antifreeze and distilled water. Been treating me nice since 2017.

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.

I had a bunch of Audi G11 kicking around from my Audi 100 that I used to have. Made by Pentosin, same smurf piss BMW used.

Put it in my e90 when I did the water pump.

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.

My 2029 Alltrack has developed the same problem at 50K miles. Drops about 1” for every two hours driven. You can see and smell the antifreeze.

Coolant ran out and since using this coolant (which was selected based on Halfords recommendation) the coolant has been running out weekly (with no obvious leaks) and the temperature gauge hitting the red after 10 minutes of driving. Not had any issues previously. Does using the wrong coolant cause these problems, or is there potentially something wrong with the coolant system?
