Any experiance, advice or cautions would be appreciated.

a. Regular auto AF is no more poisonous to fish that PG. Look up some MSDS sheets on the net to verify this. Remember, what is poisonous to people and what is poisonous to fish is very different.

b. Regular auto AF has NO PLACE in your drinking water systems. This is why most people recomend PG, since people can make mistakes. Make sure you do not. Yes, it is poison.

c. Both are equally biodegradable. Bugs dont know the difference.

d. DO NOT use windshield deicer. It is methanol or ethanol (less often) and can be very harmful to seals. It can also be flamable, depending on the consetration. Do not use it anywhere on the boat. It is also poisonous.

e. The spent used AF is recyclable at the marina or any gas station. EG or PG, but NOT the alchol types.
