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...

I've been getting Prestone for the last couple years (no mention of ethyl alcohol on it's labels)....I accuse the other stuff of causing a toilet seal leak on my last rig.
