I don't know about anit-freeze, but oil you can take to the local parts store.

Used to leave old batteries next to the front of my garage and they would evaporate within 24 hours.

Always heard you could put anit-freeze out in bowls and get rid of stray animals in your neighborhood.
Doesn;t sound nearly as sporting as a friend that was in special forces. He would go blackout then sit on his roof and scope out then plink the strays in his neighborhood. Said somehow he could tell if they were strays or just neighbors animals roaming at night. Maybe he just took out anything without a collar.
