If motor oil + WVO equals sludge.....then?

.......then what does clean motor oil + biodiesel = ?????

I scored some very nice barrels. They were only used once and contained new synthetic motor oil. I got the barrels and don't know if I can get the remaining small amount of this new oil out of the barrels through the small 2" bungs.

As such a small amount of this oil that is left in these nice metal barrels, could I just fill up with biodiesel without worrying about the small amount of remaining oil from turning some, or all of the fuel into sludge????


Thanks

I would prop them up at a 45* angle in the sun. Let the heat loosen up the oil and run out the bung. Put a clean cotton rag between the barrel lip and the rim of the bung and get the remaining couple ounces. THen proceed.


Closed head steel drum....be aware of what wvo may do to the lining of the drum, if any. There is a slight chance poly could develope if used long term.

OK I'm not going to be putting wvo in the closed steel drums. I'm going to be putting biodiesel in there. Any chance of poly with biodiesel? But primarily if any of the synthetic oil mixes with the biodiesel, is this ok? I wouldn't hesitate to just put regular petrol diesel in there because the oil would only serve as extra lubricity, but I'm worried about biodiesel mixing with the oil because of sludge. Any worries here?????

I would say clean it the best you can, and rock on.

Don't even bother cleaning them out as long as there's no water. I always buy oil drums to but my bio or WVO in. Sometimes they have a gallon or more of oil left in them which makes the drum free at the price of fuel.
