👉 Tar fluid is a thick, viscous liquid primarily composed of hydrocarbons, resins, and other organic compounds derived from the distillation of crude oil. It is often used as a lubricant and sealant in mechanical systems, especially in older engines where it can help reduce friction and wear by forming a protective layer between moving parts. However, tar fluid is also known for its unpleasant odor and potential environmental hazards due to its toxicity and the pollutants it releases when burned. Proper disposal and use in controlled environments are crucial to mitigate these risks.
