Oil (Delo 400) and water question?

[PUMPERDUDE]

Our bulk tank at work either leaks or has a condensation problem. After filling a five gallon bucket with it ,maybe a 1/4 inch of free water will settle out of it. Is it safe to use just pouring out "the good stuff"?... . Boss man wants to use it up then start keeping it in drums... ... Would you put it in Your Cummins?

I am no oil expert but if infact it is h20 in the oil than I would think that a seperation of fluids before filling the crankcase would be fine wouldnt the h20 cook off and go out the vent



Like I say I am no oil expert but this is what I think

Two words come to mind.



Heck NO... . not in my truck. :--)

I once tried salvaging 25 gallons of Delo in a drum with about an inch of water in it. Separated it out good but it turned white after running in an engine. I ended up having a lifetime supply of chainsaw bar oil. Try it in another rig besides the Cummins and see if it turns gray/white.

Yeah, I would not use the oil. The oil would be fully saturated with water even after separating the 2 layers. In any case the water can promote nitration of the oil even during storage. Also, Delo is not very toxic and microbial growth could also be a problem. Both conditions lead to gunk in your engine and/or filter.

If the oil is contaminated ... . there will always be emulsified water in the oil ... in order to use it . . the oil would need to be redecanted. However this may not remove all the water. You can also get it out using a centrifuge ... but for what you want to do with the oil ... it's not worth it ... replace the oil and use the junk oil in your chainsaw ...

Thanks for the replys. I think I'll keep my Cummins on it's Rotella diet afterall.

I doubt if the oil would hurt anything if you drain the water off the bottom. Any water in the oil will evaporate and eventually go out the crankcase vent.



However, I don't think I would run it in my Cummins. It would just not be worth taking the risk, plus, with no positive crankcase ventilation, it may take longer for the water to be evacuated. I don't think I would think twice about running it in an older gasoline engine. For one thing, that engine would not be as valuable as the Cummins, plus it would most likely have a PCV system.



How much oil do you have that has water in it? I know there is always a need for oilcan oil, or oil to paint on something for rust protection, so you may be better off just using it up that way.

I do have an old oil burning 4-Runner

How much oil do you have that has water in it?

90 gallons

there is always a need for oilcan oil

Lots and lots of sqirting .....

Not true, the oil makes a barrier to evaporation. A puddle with just a film of oil on it won't evaporate. To "boil" the water out the temp would have to be in excess of 212°F, not good for the oil or your engine. If you want to try it in your 4 Runner add a quart of the watered oil when needed just before your next oil change. If the oil turns gray/white don't use anymore of it. I can almost guarantee that it will discolor. Been there, done that.

True at atmospheric pressure. That's why I would not do it without a possitive crankcase ventilation system which puts a slight amout of vacuum on the crankcase that will pull moisture out.

I wouldn't use that oil to lube anything other that the door hinges, bicycle chain, chainsaw chain, etc. I think you get the drift.

Oil and Water? Didn't some great philosopher talk about that?
