Re-refining used engine oil offers a multitude of benefits:
Environmental Protection: It reduces reliance on virgin oil, conserving precious fossil fuels and minimizing the environmental impact of oil drilling and refining.
Pollution Prevention: Proper disposal prevents soil and water contamination from hazardous chemicals in used oil.
Energy Conservation: Recycling uses significantly less energy than producing new oil from scratch.
Resource Recovery: Valuable components are retrieved from waste, giving them a second life and reducing reliance on virgin materials.

The heart of the process lies in distillation. The oil is heated under vacuum, causing various fractions to evaporate at specific temperatures. Lighter components like gasoline and diesel are separated first, followed by heavier fractions used for lubricants and asphalt. This fractional distillation essentially disassembles the used oil, extracting its valuable components.
