I've seen a few videos on Youtube describing use of waste oil for burning in a furnace.
Cooking oil may not be the greatest, and I am sure it also has some negative properties, but burning used crankcase oil from a car in a oil heater?
One nut job claims "it's clean burning". The heavy metals, other chemicals and unhealthy byproducts from this kind of waste...what is with these people? Are they foolish, ignorant?
Is it that they just don't care at all what they are doing to the environment?
How is it that none of these ignorant criminals are not being caught and fined? The evidence is right there on Youtube. Sometimes I think it should be called Youboob!
