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...

Yep, ethanol in RV antifreeze is pretty common. It allows it to be cheaper, and provides a germ-killing effect as well.
