Will a centrifuge remove coolant from waste oil? Inlay have access to a rather limitless supply of WMO from my former employer. The issue is, I know what got dumped into those tanks, had a few batches I dumped in from drop offs that were loaded with water, which I know can be separated with the 'fugue, but also allot of coolant. Will there be any nasty surprises when i pull the product out of the filtered barrel?
Coolant poured into oil that is only sitting separates. But the problem with engines that have blown head gaskets and ran for a while whip the oil up into a "milkshake". You'll be hard pressed to separate that.

I work for the ford and dodge dealership , I have access to all their used motor oil but it has coolant mixed in with it too. I have the same question! I wonder if it seperates like water or if it will mix?
the easiest way to remove the water is to heat the drum of the mixture and let the coolant/water settle to the bottom then drain it off.
Will a centrifuge just milkshake it then? I don't know if I'll have a heat source for my drums right off the bat, so heating may not be an option for a while
could you detail your setup please? I have access to WMO also.. but have had too many suggestions as to how to filter it down to (what?) microns. so if you could explain the "kit" and method that would be greatly appreciated. My 9 trucks wait (hungrilly ) in advance of your knowledge!

You can only break an emulsion in mineral oil with heat. To properly centrifuge the oil you'll have to get the oil up to about 90 to 95 degrees C in order to get any and all impurities and water out of the oil through a centrifuge. If you run oil cold through a centrifuge you will not get the separation of solids out of it. And yes, if you run oil with water cold through a centrifuge you will create an emulsion.
One way to do it without a centrifuge is to heat the drum and then let it stand as Kohburn stated and then decant the oil off the top. This will be the cleanest in the drum. The hard part is finding the interface between the oil and water.

I talked to the guy at the dealerships , and he said there is a ton of coolant in the oil in the big holding tank, what he suggested is me leaving a few 55 gallon drums there and all the techs will put the ATF in one and motor oil in the other. Sounds like a plan to me!!

I have a Q about this: Speaking of strictly waste motor oil that's contaminated with water and/or anti-freeze, if one heats the mixture up to say 100 degrees F, would the water and anti-freeze evaporate out od the top of the drum?
And let's say that you just get it up to the 100 deg. F temp. and don't necessarily wait for anything to evaporate; would you say that the centrifuge would then seperate the water and anti-freeze from the oil since it is now heated?
Coolant in oil, can it be separated?
