The differences between non-standard diesel and national standard diesel are as follows: Color: Generally, high-quality diesel for vehicles should be a transparent liquid that is colorless, light yellow, or light brown, slightly transparent without any turbidity. For more oil-related information, oil product details, and oil blending techniques, you can follow the oil product circle. Diesel that appears black, dark, or soy sauce-colored is low-grade blended oil; diesel that appears turbid is inferior oil mixed with water or impurities. Odor: High-quality diesel has a normal oil smell; inferior diesel has a pungent odor, such as a strange smell or a spicy and unpleasant odor from recycled oil. Texture: High-quality diesel has a low viscosity to the touch; diesel that feels too thick is inferior diesel mixed with other lubricating oils.

Can I go to any 4S store for the first maintenance of a new car?

The first maintenance of a new car can be done at any 4S store of the same brand nationwide. As long as the vehicle is within the warranty period, it can be serviced nationwide, and the maintenance records can be checked as the backend maintenance systems are interconnected. However, before the first maintenance, remember to bring the vehicle's maintenance manual or the first maintenance card. First maintenance items for a car: Car lights: Car lights include emergency signal lights, trunk lights, glove box lights, indicator lights, dashboard warning lights, and passenger compartment lights. When these lights are not working, they need to be carefully checked. Car tires: For tires, the wear condition and tire pressure need to be checked. If the tire pressure is insufficient, it should be repaired and checked at a professional car repair shop. Car oil: Engine oil is divided into mineral oil and synthetic oil, with synthetic oil further divided into full synthetic and semi-synthetic. Full synthetic oil is the highest grade. When changing the oil, refer to the vehicle's user manual and follow the recommended specifications. Note that the oil filter should be changed along with the oil. Mineral oil should be changed every 5,000 kilometers or 6 months; synthetic oil should be changed every 8,000-10,000 kilometers or every 8 months. Condition of the car's underside: When driving on general roads, sedans have a slightly lower chassis than SUVs, so when passing over higher terrain, sedans may scrape the parts underneath the car. Therefore, after driving for a while, it's necessary to check the fuel pipes, dust covers, rubber protective parts, and the car's chassis fixation. Check areas with screws and tighten them.

What are the maintenance items at a 4S shop?

4S shop maintenance items include: interior and exterior lighting electrical appliances and electrical equipment, airbags and seat belts, tires, engine lubricating oil, power steering fluid, and vehicle fault code inspection. Inspection of interior and exterior lighting electrical appliances and electrical equipment: Check whether the vehicle's bulbs are consumable parts. While driving, it is difficult for the owner to detect whether the vehicle's lights are functioning properly, such as brake lights, which are easily overlooked, thereby creating traffic hazards. Airbags and seat belts: Airbags and seat belts are life-saving tools in the event of a vehicle collision, and whether they can function properly is crucial. Therefore, the inspection of airbags and seat belts is also very important. Tires: Tires are the most important and safety-related part of a vehicle during operation. Tire inspection mainly includes two aspects. The first is to check whether the tires are damaged, punctured, scratched, or have sidewall bulges, and the second is to check the tire wear condition. Engine lubricating oil: Mainly check whether the fluid level is negative and whether the oil has deteriorated. The fluid level can be seen through the scale. If it is below the scale, it needs to be replenished in time. Power steering fluid: For vehicles equipped with mechanical power, it is necessary to check the power steering fluid. It is generally recommended that owners replace the power steering fluid every 2 years or 40,000 kilometers. The power steering fluid can be judged by the scale to see if it is insufficient. Vehicle fault code inspection: Vehicle fault code detection must be carried out at a brand-designated 4S shop.
