Running Used & Filtered Waste Motor Oil?
 

I have seen some discussion on this. Allot of positive but no real cold facts... I am wondering if its ok to run used and filtered waste motor oil, or hydro fluids? If filtered to one micron or even centrifuge filtered to SUB-micron if it would be ok? I heard lots of good things about the 12V engines but what about the 24V??? If the Vp44 is fuel lubed i would think that it would LOVE waste motor oil?

Any opinions? Facts? Hearsay?

Thanks!
:pca1:

i know at my last job there was alot big rigs running there used oil in with the fuel, but on the new trucks it was killing them like flys i put atf in my fuel everytime i fill up which i belive saved my vp for a long peroid of time cuz i hade a heavy foot :w2:

You can run out board TWC-3 at 1 Oz per gal. Save some money get it at Wal-mart.

I burn my used motor oil in my big trucks (dt 466 and series 60) but I have not tried it in my dodge yet:humm:

yep
 

I regularly run at least 2 gallons of centrifuge filtered WMO in a full tank of #2 in my 2007 5.9 common rail. Runs just fine and hasnt caused any problems or thrown any codes in almost 2 years of doing this.:U:

The biggest problem with WEO/WMO is the metalic debris... Most people try to filter it with another filter and magnets but that doesn't get it all. There is a lot of other metal (non-ferrious) in the oil that a magnet won't pick up.

I would even burn the oil out of my Frantz Filter (good down to 1/10 of a micron). But I've never done it yet. I guess I'm just chicken... :humm:

Now a centrifuge is safer by far. It will pull out most of all the debris for you. But there is only one last thing that might have a effect on some trucks and that is ASH content. So oils have a much higher content level than others.

This why the conscept of ASHLESS 2 cycle oil started was that some people were burning waste oil, some were burn ND-30W new oil and still having issues. But at least the 2 cycle seem to be the safest. (Just a personal opinion)

I plan to run filtered waste trans fliud in my 6.2 this summer to see how much it can handle. but for the most part i wanted to make a mix with a lil diesel a lil veggie and allot of waste ATF. Well see how that does soon.

Thanks for all the suggestions. I have been looking at filters. I would love to get a centrifuge... I want one BAD for in-line oil filtering, but cant afford them at ALL. Filters look like my best bet. I will give some of the other additives a shot.

I was thinking of waste tranny fluid too... I could probably get allot of that from the shop i work at driving tow truck. We have a service shop too.

The only non magnetic metals i would assume that would be IN your oil (in dangerous quantities) would be copper or possibly aluminum? I would think if you had high quantity of those you might be in some trouble. Just a thought. could be wrong of coarse!!

I wouldn't recommend mixing veggie with ATF or WMO. It tends cause it to coagulate and will clump up in your fuel filter and eventually cause a blockage.

In the fuel additive test done on DP that has been posted here wast engine oil would increased wear on the pumps. ATF is a very bad idea there are friction modifiers in modern ATF that too will increase wear. ATF is basically Hyd oil with friction modifiers so Hyd oil might be ok.
