I agree - I avoid the ethyl alcohol stuff. Really don't need to add anything else flammable to the rig... I prefer to use the Prestone when I can get it, too.
Now here I go again ruining someones day with facts. Just for your information, both ethylene glycol and propylene glycol ARE FLAMMABLE just like the ethyl alcohol . . . . . . stuff.
The open cup flashpoint for propylene glycol is 225 F. That's known as the temperature that it must be heated in the presence of an ignition source so that the vapor that comes off it will sustain a flame. The autoignition temperature for propylene glycol is 700 F. That's the temperature that, in the presence of oxygen, it will light on fire all by itself. (spontaneously combust) For ethanol, its about 690 F.
If your RV is already on fire, all three, ethanol, ethylene glycol and proplyene glycol have no problem adding to the flames.
Sorry to ruin your day. As an added sidenote, many classes of racing ban alcohol and glycol based coolants because of the fire hazard.
