    2 gallons of cool blue and distilled water for whatever would fit back in.

    Default Uh oh...

    OK, total noob question: We are supposed to dilute that coolant stuff? ARGH! I got the coolant message about six months ago and i just topped it off straight out of the BMW coolant bottle. Bad idea?

    I think Im right in saying that distilled water isnt the stuff to use. Its very aggressive, causing some elements in the metal to leech out over time.

    It does the same in humans and is suspected of promoting osteoporosis amongst the health freaks that eschew normal 'mineral' water and drink distilled instead. A search around on the web a while back convinced me of this - as well as posts I made on this site which were confirmed

    You should therefore use de-ionised water. To avoid your car breaking its little tibia or something...

    This is a hot topic. However, it really doesn't matter as long as you change the coolant every 3 years. Otherwise, people say use only BMW coolant... I'd rather use MB coolant instead.

    In my BMW now? The green stuff... so buy whatever you want to... just remember to change the coolant every 3 years regardless of what you put in.

    The premixed coolent is an interesting product... using the "right" water vs. using "distilled" which is detrimental to metals if poured directly in... if you premixed the distilled water with coolant, then it is safe.
