My friend has a cummins 12V that he runs up to 50% old eng oil in, smokes kinda bad sometimes but runs fine, from the barrel he pumps it (30 PSI) through two fuel filters off an old truck engine, (filters are new) and a water separator,also off a big truck. He is trying to get transmission fluid from a local shop as its normally cleaner and closer in makeup to diesel fuel. The filters are from the local NAPA, and are pretty cheap. Parts were cheap from a big truck graveyard, and the 120V hydraulic pump wasnt too expensive.

I would highly recommend this type of filtering. No filters to change only bowl to clean out. Will remove water from diesel.
on where to get the equipement, what are the results??

My dad is running 80-90% double filtered used ATF that he gets from a few shops around town in a 12v and the truck runs fine, other than the smoke. And the smoke will thin out to nearly nothing if the truck has been running for a while, so I would think you would be good to just heat the fuel. Only real problem I have with running it that concentrated is the thing can be a pain to start under 65* if its not plugged in and the smoke residue is kinda you have to wonder what all is accumulating in the turbo and all...he just drives like it he stole it every so often and blows out a big cloud and keeps on truckin

WEO/WMO has it place... Like Cummins already produced Centinel which is a device that pumps WEO/WMO out of the crankcase into the fuel tank. But this was designed for the bigger Cummins trucks and engines...

But still in all there is a lot of prcessing that should be done... Filtering with a centrifuge and media is the best bet. As for the magnet idea it only picks up the metal... how about luminum and other non-ferious metals?

I'm curious if the centrifuge will filter out the carbon particvles too???

Don't the newer CR Cummins engines require a 2 micron filter? They are very sensitive to debris in their fuel systems. Its seems that if they only filer to 2 microns, than anything smaller wouldn't be a major factor.
Some of the older freight lines back in the 70's and 80's used to just mix old engine oil into their bulk fuel tanks, then filter them once at the pump. Other than a higher build up of carbon on the fuel nozzles and on the pistons, no problems.

I've dumped it from my drainpan into my transfer tank,back when I did not want to bother keeping it around,it quieted the engine a little,Fuel mileage was not as good,just about a draw.
I've got some barrels now,and am collecting it,going to build a small steam engine,powered with waste engine oil.(someday,when I can afford to)

Very good idea!

But I would at this point only suggest the WEO/WMO for the older trucks.As the trucks got newer the fuel system got tighter in design and don't tolerate debris as good. The old engines you could pump anything through it...

I have a dieselcraft centrifuge and ive been thinking about cleaning my UMO with it after each oil change. Then running it through a big ol magnet a few times and topping off my 200 gal. aux tank with it.
