CONVERTING WASTE MOTOR OIL TO DIESEL FUEL Converting used motor oil to a useable fuel source. Currently, the market for used motor oil has stymied many recycling and reclamation efforts. The market for used motor oil has largely been geared to limited processing steps which convert the used motor oil into a low quality fuel such as bunker oil (#6 fuel oil) . Alternatively, a limited amount of used motor oil is reclaimed and converted into a recycled motor oil product. Used motor oil retains a high energy potential. However, hazards and cost associated with collecting, storing, transporting, and general handling of used motor oil has limited the efforts to collect used motor oil for disposal or recycling. Although the prior art provides limited processing of used motor oil for other petroleum products, there remains a need for improvement within the art of converting used motor oil to a high quality energy source. Waste oil from internal combustion engines can be cracked under low temperature, low severity conditions to yield a number two grade diesel fuel. The starting hydrocarbon material, used motor oil, is characterized by a mixture of parafins, napthenes, aromatics, and olefins. above thirty percent distilled, cracking becomes vigorous between 60 and 650°F. The condensation temperature of the distilled material never exceeds the maximum boiling point temperature for #2 two diesel fuel. Therefore, in terms of boiling points, the cracked material meets the specifications for #2 diesel fuel. Metal particles are typically in the micron and submicron range and represent particles sufficiently small such that they pass through standard oil filters.

And to think I use all mine to start my bonfires each spring & fall.

It would seem that filtering to the average fuel filter micron [ 10-20 ] & burning in tank at 3-6% is a good way to recycle .

this scares me...........I think if I were to put used motor oil in my fuel it would hafta be filtered down to get all the metal particals out

all the use motor oil we go through with our heavy machinary and dump trucks, we probably go through about 100 gallons a day and all that use oil goes right into our holding tank to be used tordes our oil heater in the shop. now when summer comes we just store the oil in big tanks

If it could be filtered down to 1 micron I would think it would be a lot safer then using it right out of the oil pan and putting in in your fuel tank as many oil filters only filter down in the 20-35 micron range.

I would filter it to at least 2 micron and then run it thru a strong arsed magnet to get the metal particles out.

hmmm...I've got plans for a waste oil furnace that fuels itself and condenses the stack exhaust into clear fuel oil. The only by-product is ash and no stack opacity once up to temperature. Anyone interested in trying it out? I haven't had time to build it yet, but the plans are solid and requires a very small foot print. Can be made out of everyday shop materials and hardware store parts.

Yes I am fuel just hit 4.05 a gal here in south jersey and I want to make my own fuel, my own small way of sticking up the oil companies butt to put it nicely.

this would be awesome to do since we get so much waste oil from the oil changes at the garage! has anyone came up with a clear formula to mix it in with regular diesel or do you have to do some work to the oil first?

I give my waste oil to a friend who is an over-the-road trucker. He has no qualms about dumping a couple of gallons in that BIG fuel tank and running it in his big truck.

I'd rather give it to him than risk my VP44... At least until I move to Colorado and get my garage outfitted with an oil-burning heater.

If I remember , one of the average smallest fuel filters is about 7 micron [ I mean stock , what the builder feels is the max allowable ] .
So that as to particles , should not be a problem , but we seem to be a bunch that likes to make things better , so some after market filters going around 2-5 micron , then by pass & centrifuge going sub micron , the particles being out ?
Then other issues are PH balancing , water ect. , this is just one more reason I went looking for the 12 P-pump .
I know I have the link for fuel recommendations , but have so many , that I can not find , there are about 4-6 things that were allowed in the P-pump engines , oil being one of them , but filtering , water & PH should be addressed .

Burn 1200 gal/year in my Reznor heater, shop 8000 sq. Get 3 loads of ash out of it during the season.

if diluted properly I think the pH would be of little concern, but there is probably a lot of junk in there that would need to be filtered out.

There are several centrifuges on the market that will filter to 1/10 of a micron for under $300. One unit will filter 55 gal of oil in 2hrs. We can fight the oil companies by recycling smartly. It will take some time,money and effort but if we keep paying their prices they'll keep charging more. Centrifuge co. Spinclean also dieselfuge
