The indicator for insufficient oil resembles a small teapot. When the engine oil warning light illuminates, it indicates an abnormality with the oil. In some vehicles, when the oil warning light comes on, it may not display the specific fault condition of the oil, requiring manual troubleshooting to identify the issue. Below are relevant details about oil replacement: 1. Check the oil dipstick: The simplest method is to directly inspect the oil dipstick. If the oil level is below the minimum mark, it's time to replace the oil. 2. Oil deterioration: If the oil emulsifies, shows foam, turns black, contains impurities, or has reduced viscosity, it should be replaced promptly. 3. Engine noise: Unusual engine noises, such as sounds from within the cylinders, may indicate that metal shavings from mechanical friction have entered the oil pan. These particles can be carried by the oil to the pistons, causing knocking sounds in the cylinders. In such cases, the oil contains many impurities and should be replaced. If necessary, the oil pan should also be cleaned.

How Long Until a Passenger Car is Scrapped?

For household 5-seat passenger cars and 7-seat SUVs, as well as non-commercial small and mini vehicles, there is no usage lifespan limit. When the normal mileage reaches 600,000 kilometers, the state will guide the vehicle to be scrapped. In addition to the above-mentioned vehicles, small and mini non-commercial passenger cars, large non-commercial passenger cars, and wheeled special-purpose machinery vehicles also have no usage lifespan limit. Commercial vehicles have scrapping time limits as follows: Small and mini taxi passenger cars have a scrapping time limit of 8 years, medium-sized taxi passenger cars have a scrapping time limit of 10 years, and large taxi passenger cars have a scrapping time limit of 12 years. Public bus passenger cars have a scrapping time limit of 13 years, other small and mini commercial passenger cars have a scrapping time limit of 10 years, and large and medium-sized commercial passenger cars have a scrapping time limit of 15 years. Mini commercial trucks have a scrapping time limit of 8 years, light and large commercial trucks have a scrapping time limit of 10 years. The vehicle scrapping process is as follows: The vehicle owner applying for scrapping and renewal must fill out an "Application Form for Vehicle Modification, Transfer, Alteration, Suspension, or Scrapping" and affix the owner's seal. The registration office will accept the application and issue a "Vehicle Scrapping Notice" for vehicles that have reached the scrapping time limit. For vehicles that have not reached the scrapping time limit, the vehicle inspection office will determine if they meet the scrapping standards and issue a "Vehicle Scrapping Notice" if they do. The vehicle owner can choose a qualified recycling company to dismantle the vehicle with the "Notice". The recycling company will dismantle the vehicle and take photos after verifying the "Notice". The engine must be separated from the vehicle, the engine block must be broken, and the frame (chassis) must be cut. The vehicle owner must submit the "Modification Form", "XX Province Vehicle Renewal Technical Appraisal Form", "Scrapped Vehicle Recycling Certificate", and photos of the dismantled vehicle to the vehicle inspection office for verification and signature. The license plates and certificates will be reclaimed, and the scrapping registration will be processed according to regulations. Special Notes: According to Article 30 of the "Motor Vehicle Registration Regulations", if a vehicle cannot be driven back to its registration location due to damage, the vehicle owner can sell the scrapped vehicle to a local motor vehicle recycling company. If a commercial vehicle is converted to a non-commercial vehicle, it must be scrapped according to the original commercial vehicle's scrapping time limit. According to Article 43 of the "Motor Vehicle Registration Regulations", after completing the transfer or cancellation of motor vehicle registration, the original vehicle owner can apply to use the original license plate number when registering a newly purchased motor vehicle. The application to use the original license plate number must meet the following conditions: (1) The application must be submitted within six months after the transfer or cancellation of registration; (2) The vehicle owner must have owned the original vehicle for more than three years.
