Municipal waste management (trash) operations generally have (free) collection locations for used oil/coolant. Alternatively, comprehensive auto service centers (probably NOT a straight up gas station) frequently accept/collect auto fluids as to the major auto-parts stores (Autozone, etc).

Posters are correct - DO NOT dump in sewers etc.

However, I hear from some hospitals that antifreeze-coolant, served on the rocks, makes for a refreshing summer beverage

 

I just watched a show on ID about a chick who poisoned two husbands with anti-freeze mixed in green jello . Crazy bish

 

i saw a show where some crazy chick mixed it with gatorade.

i heard that straight antifreeze does taste very good and manufacturers have to mix in an ingredient that gives it a bitter taste so people won't try to enjoy a refreshing drink, but then die shortly there after.

 

If it is so environmentally safe, offer him a nice tall glass of the stuff. 99% sure he will decline.

 

I just got rejected at Autozone today because they only take used oil.

Lucky for me there was a Firestone right across the street and they took the antifreeze no problem.
