Blue BMW Coolant - discuss....

[MR 325]

PS: For those who think BMW coolant is too expensive... It's not like you change this shit at every oil change! Pony up the extra few bucks and be good for a couple years. (Or however often you flush coolant).

I always run BMW coolant, no joke.

I've seen inside motors run on water, not pretty.

hrm...water? its almost free, water is the main cooling additive, it doesn't kill the environment wen i dump it on the street, and in LA it doesn't drop below freezing.

if i run coolant/antifreeze its usually 30% or less. wal-mart special, non-premix.

"blue" is supposed to be for BMW engines since it is "phosphate free" and doesn't corrode my cyl head. whatever.

Prestone and distilled water because it's phosphate free and contains gly-..whatever that chemical was called. That's all my Bentley called for, so why the hell pay $6-8 more and drive 20 mins furhter (in my case) for something else that does the same shit?

Some people swear by it - other don't even know why they might want to use it....What do you use and why. Discuss...
