What is the definition of re-refined oil?

Re-refined oil is defined as oil that has undergone a reclamation process to remove physical and chemical impurities, resulting in a product that is equal to or superior to new oil. This process typically involves methods such as distillation, filtering, and treating, which aim to restore the oil’s original properties. The fact that it meets or exceeds the quality standards of new oil signifies its potential for effective use in various applications, including lubrication and more.

This focus on high-quality output is a significant aspect of re-refined oil, as it not only supports sustainable practices by reducing waste but also conserves resources by minimizing the need for virgin oil extraction. This makes it a viable alternative in many instances where new oil would traditionally be used.

The other definitions do not capture the essence of re-refined oil. For example, oil that does not comply with quality standards would not qualify as re-refined oil, as that would imply it has not undergone the necessary processing to meet or exceed quality benchmarks. Similarly, terms related to sourcing from terrestrial environments or subsurface deposits pertain to oil extraction methods and do not encompass the reclamation and purification processes that characterize re-refined oil.
