Anyone Using Amsoil Propylene Glycol Coolant In Their Diesel

I'm a bit confused as to why the OP is running PG coolant in the first place since all the convention coolants are EG. The only place on the coach the uses PG are those that might come in contact with drinking water and the such.

Before I switched to the extended life my all Cat wanted was coolant that met their standards as stated on the bottle...that and the additive of course.
