Man I need help here. For many years my dad would put his used oil in a container and just leave it in the shed or out behind the house. So I have began to clean the place up. Somehow many of the plastic bottles have gotten water in them. They were sealed so all I can figure is that the moisture somehow went through the plastic and into the oil. The metal containers do not have any water in them. If anybody else has an idea how water got into them let me know. They only had oil in them when they were filled up. I had 1,5 gallon plastic gas can that I had oil I drained from my Jeep. It was sealed and in the garage for a few years and it's got clear water in it too. We took 60 gallons to the city today since it's amnesty day. After sitting in line 2 hrs , in the sun , no AC and it's 113* they tell they don't take oil. Only household stuff like computers. Kragen and AZ wont take the oil with water in it and they check. They Won't let me pour my own oil so I can't sneek it into the used oil drum. The dump won't take it, city wont take it, auto parts stores wont take it.
