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.
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.
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.

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?
