Here is an interesting post from a popular MINI forum:
I'm a Master Level ASE tech (plus L1 and X1 cert)., and I teach Automotive Technology at a local Community College.
You guys putting in the wrong fluids keep me, and my students who go on to join the tech workforce in business.
Let's just say in my time dealing with European cars since '93 I've seen more than a few water pump impellers dissolved, heads fail, rotted intakes, and cooling system woes.
It's simply not worth skimping on. I'm not saying you have to march out to the dealer, but you should research who makes the OEM fluids and stick to them.
People forget the chemistry in today's cars is as complex as the electronics.
