Waste engine oil from auto repair is classified as hazardous waste, and private trading or transportation is prohibited. It must be handed over to qualified units with corresponding hazardous waste disposal licenses for transportation and treatment. Unauthorized handling or trading of such waste can result in penalties, with severe cases involving three tons leading to criminal prosecution. Mineral Engine Oil: Mineral oil is the residual oil left after gasoline and heavy oil are extracted from petroleum. Although it is a natural oil, it contains more impurities compared to semi-synthetic and full-synthetic oils. It is cheaper but offers inferior lubrication for engines and has a shorter service life. Semi-Synthetic Engine Oil: Semi-synthetic oil falls between mineral oil and full-synthetic oil. It contains a significant amount of anti-corrosion additives to enhance stability and oxidation resistance. Full-synthetic oil is the highest quality and most durable among the three types, and it is also the most expensive. Typically, it can last for 10,000 to 12,000 kilometers in regular cars without deteriorating.

When I worked at an auto repair shop before, I witnessed a case where improper disposal of used engine oil led to fines from the environmental protection bureau. It happened at my friend's shop—they poured the used oil directly into the sewer and got reported by the public. The penalty standards are based on the 'Law on the Prevention and Control of Environmental Pollution by Solid Waste,' with fines starting from at least 10,000 RMB, and some regions impose even stricter penalties—for example, Shanghai can fine between 20,000 to 50,000 RMB, while Guangdong is even harsher. It's not just about fines; corrective actions are required, and in severe cases, the shop may face suspension or even license revocation. Learning from this lesson, I now always use licensed recycling companies for disposal. It costs a bit each year but saves major trouble. I advise fellow professionals not to cut corners—environmental risks are too high. If groundwater gets contaminated, the penalties could be much worse.

As an environmentally conscious individual, I believe the penalty standards are in place to encourage compliance. The state classifies used motor oil as hazardous waste, with fines for improper disposal starting at 10,000 yuan and going up to 100,000 yuan, varying by location. For instance, Beijing imposes higher penalties—a 2022 case there resulted in a 30,000 yuan fine. What's worse, after being fined, offenders must also clean up the pollution and pay compensation. I recommend auto repair shops partner with licensed recyclers rather than risk cutting corners to save money. From an environmental standpoint, recycling used motor oil conserves resources and reduces pollution. Everyone should take this seriously to protect our homeland from harm.

When I first bought my new car, I was curious about how much the fine for waste oil would be, so I asked the mechanic. The standards are quite complex, with a national minimum starting at 10,000 RMB, but stricter in urban areas, while smaller cities might impose lighter fines. I looked it up and found that if you're caught dumping oil improperly, the fine depends on the severity of the violation, and additional penalties apply if pollution occurs. A friend who worked at a repair shop once got fined 8,000 RMB for improper handling—a harsh lesson. Now, whenever I go for car maintenance, I check if the shop has proper recycling records. Don’t think it’s a small matter—the environmental bureau is strict! The simple solution: use official recycling points to stay safe.
