Hi,
It's that time again where I have to flush out my coolant, and decided to go the Motul route.
Now all I know about the OEM BMW fluid is that it is Phosphate free and it's blue-ish in colour.
Here's my dilema:
Motul Inugel Expert Ultra (Blue) is BMW N600 69.0 approved and is Phosphate, Nitrate and Amine Free.
While....
Motul Inugel Optimal Ultra (Orange) is also BMW N600 69.0 approved and is Phosphate, Nitrate, Amine, Borate and Silicate free.
So which do I take? Blue or Orange ?
