Antifreeze PEAK or OEM BMW

i use peak 50/50 Red stuff formulated for toyota lexus and scion

Not an LS specifically but I had good luck with the PEAK 50/50 pre-diluted mix from Autozone.

I used peak when I changed my rad, no issues so far

I use Peak for Asian vehicles, green in color, for my Mazda's. Get it at most auto parts stores in 50/50 mix so you never worry about cold temps in winter.

Peak final charge is compatible and meets all necessary specs. Bonus is it's available almost everywhere in the US and Canada

I use peak 50/50 blue European with no issues

I used the Peak coolant that was pink, it's been a few weeks and no catastrophe so I think you are fine.

I use the purple peak G13 in mine - from autozone. Its actually more pinkish when it pours. Made sure to flush with distilled water before adding the new coolant just in case but its been fine in my car. Don’t overthink it!

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

I don’t use peak anything. it’s actually not great coolant.
