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...

Read the labels. Some contain ethyl alcohol, some contain only propylene glycol, some contain a mix. I use the ones with only propylene glycol.
