Antifreeze Pentosin or OEM BMW

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.

Pentosin has good equivalents.

The blue stuff is definitely better than the green from my experience. I use the overpriced bmw shit but I think you could probably use the cheap blue stuff just as well.

Don't buy BMW coolant it's overpriced just like everything else they sell. Blue coolant is preferred but the premixed green stuff isn't going to cause catastrophic meltdowns. My 97 328i has the green stuff and I've got no issues after 196k miles.

Drain/refill every two years for me, Pentosin coolant only!

I used 3 of those Pentosin blue with a bottle of Water Wetter and the rest is water.. my temp is 30 degree higher than it was before and I don't know what the heck it was in there before which is this yellow/green milky stuff, it sure kept the engine mostly below 180. But now I hit 220-230 easily
