Does your RV Antifreeze contain Ethyl Alcohol?

Maybe I've been living underneath a rock, but I didn't know ethyl alcohol was ethanol. Ethanol is widely known to degrade rubber/plastic seals and hoses in older engines, especially older boat engine...

that was real common a few years ago. More and more take a look at the label. Many that used to be just propylene glycol now have a mixture of propylene glycol and ethyl alcohol.
