With Evans NPG+ they have not had any loss of coolant or any overheating issues. They work just fine under the same extreme conditions.
People equate the "boiling over" with overheating when it's just not the case.
Having a boil-resistant coolant can be damaging if your engine reaches too high of a temperature. The pistons will get too warm and start scuffing.
Just because it's not boiling, doesn't mean it's running below "overheating".
Just look at your termparature gage to see if it is overheating.
My engines have not overheated or even run hotter with Evans NPG+. The thermostat does its job just fine maintaining the desired engine operating temperature.
