I think you're makin' up that biodegradle part..
or ....OK, biodegrades in 500 years.

I just looked at my gallon jog of Dexcool..
says   WARNING !     'contains ethylene glycol'  ..

says do not drink, do not breath mist or vapors.
Avoid prolonged skin contact.
Avoidskin and eye contact.

In other words ..it's a deadly poison.

perhaps you are thinking of a less poisonous a-frz.
The common brand is Sierra ..
I think it's propylene glycal rather than ethylene.
It won't kill your dog ...or at least not as well as ethyleneglycol will.

I love this Frank Zappa quote ..goes something like ..
'Scientists say the universe is made up of mainly Hyrdrogen. I disput
that ...it's made up mainly of stupidity' ...

something close to that. Google it perhaps for the exact wording. .
We wouldn't want groupmembers thinking they can poor out their oil
Dexcool on the groundafter all.
