That said, replacing your cooling system PARTS every 70k is the only surefire way I know to almost eliminate cooling system problems.

I had time to see the actual bottles of coolant the stores have , smolck is right , i have to admit it is too confusing what with Prestone and peak changing to "continent " specific packaging, so much easier to use the BMW fluid.
I will finish my last gallon of Peak global and will go back to bmw blue for convenience sake.
companies tend to change formulations and packaging and its hard to keep up.
You never know if its phospate free or not.
