I have several gallons of old fluids. For the most part, they are not separate though. I could probably drain most of the oil off the antifreeze, but it also has trans fluid, power steering, etc.

Where can I take this stuff to dispose of it legally?

I think I have 20-30 gallons total.

I think I remember hearing autozone takes old oil but I assume thats pure oil and not contaminated mix. At my old shop we always had to keep used oil and antifreeze separate for when the guy came to take them away.

I was thinking I could just get one large barrel like 25gallon, pour everything in it, and take it to one main location and they can process it. I am willing to pay a few bucks as well, doesn't have to be free.

edit: I found that there is a haz-mat collection day at Bergen Community College in Paramus in April(the march one is on a day I already have plans). I'd just have to swap stuff over to smaller containers(max 5 gallons) and try to separate it some. However i'd rather just get rid of it all at once as is.
