Just wondering and dont know if this is the correct section. If it is I apologize. What happens to all the used oil filters, fuel filters, and coolant filters and trans filters? I know SAFETY KLEEN takes all of ours and does not charge us, but what happens to them after SAFETY KLEEN takes them? I would imagine they recycle the steel out of them, but could they take remaining oil and atf out of them? Other question is this; I have around 2 3/4 gallons of honda anti freeze(blue dyed) that I need to dispose of since I flushed my engine, and drained and refilled the whole system(including the block drain or engine). Who will take anti freeze? Advance said they dont take it and Autozone said no also. Didnt ask NAPA yet. Thank you very much in advance.
