Default Re: Antifreeze History?

I don't know what truth there is to this but I read that Ethylene glycol was designed for use in pressurized systems and that Propylene glycol works better in unpressurized systems beacuse it's not as prone to boil over. I run prestone Low Tox in my Town Sedan it's Propylene glycol you have to use the litmus paper test strips to test the mixture. it was easy to find a few years ago but harder to find now. Thanks to this thread I may check into using RV antifreeze.
