Abstract: An apparatus for on-site engine oil reconditioning comprises an apparatus configured and arranged for changing oil by removing spent oil from, and introducing reconditioned oil into an internal combustion engine. A mechanism, in fluid communication with the oil changing apparatus, removes finite particles from the spent oil to produce particle-free oil. A mechanism, in fluid communication with the finite particle removing mechanism, refines the particle-free oil to remove water, fuel, and/or glycols to produce re-refined oil. A mechanism, in fluid communication with the refining mechanism, adjusts the composition of the re-refined oil to meet a predetermined specification to produce the reconditioned oil.
