When I change my oil I place the used oil in clear 64 oz plastic soda bottles. Make sure you get the bottles with the clear bottoms and not the plastic cap. I let the used oil sit for a day in the bottles. Any antifreeze will show up at the bottom of the bottle. If you see a little clear spot it's OK. That the left over coke. Green liquid is not good.
