Re: Evans NPG+ Waterless Engine Coolant
In their marketing spiel, all they talk about is a higher boiling point. You have to dig ( http://www.evanscooling.com/html/npgPls2.htm ) before you find out that it also has less heat capacity ("specific heat") than regular coolant, and is significantly thicker.
It's a good thing it has a higher boiling point, since that makes it much more likely that you'll need it. You would have to pump much more of it through the engine to remove the same amount of heat as standard coolant, and its higher viscosity makes that difficult.

No, she hasn't been drinking antifreeze since before we got married
I'm more interested in any thoughts or experience with it as an engine coolant, and not with its toxic properties. But thanks anyways.
