For 45 yrs read/heard that is critical to use 50/50. This forum is the very first deviation to that recommendation I've ever come across.

Stig, if you go to an auto parts store and find a bottle of full strength coolant, you'll see the various mixture ratios and their intended application.The purpose of antifreeze is to lower the freezing temp and to raise the boiling temp. 70/30 coolant/water is best to prevent boil over.
