I’m running 110k miles in my M40 X3. There was a coolant issue but other than that it’s been an excellent engine.
I use peak violet european formula in my mk8 R.
I use BMW coolant cause it's similar in price, so why not. Actuall,y a little cheaper cause my dealer does discounts
I use Peak, and I think they recommend the violet stuff.
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 just use peak pink made for Alfa Romeo and European vehicles overall and it works fine!
I've mixed Peak Violet in with the OEM G12+. My car ran normal for several thousand miles like that.
coolant is always best. I would get rid of the green coolant, flush it all out and replace with something better. I use Peak Final Charge in everything.
I've used the PEAK Asian pink coolant in my Camry in a pinch, but OEM is worth it. (For my 2013 prius and 2014 camry, they use the pink colored fluid)
330i, coolant repairs.
