As an owner who has driven an Infiniti Q50L for several years, I can share my experience: My car is the 2018 model, and the original run-flat tire specification is 245/40 R19, with the brand being Dunlop Sport Maxx RT2. Run-flat tires are quite practical; if the tire gets damaged, you can still drive up to 80 kilometers to find a repair shop without the hassle of changing to a spare tire like with regular tires. I think this design enhances driving safety, especially when encountering problems on the highway at night. However, the downside is that sometimes the ride feels bumpier, particularly when driving over rough roads. The tire specifications must match the rim size, otherwise, it can affect handling. I recommend new owners check the configuration sheet to confirm the specific model when buying the car, and regular maintenance of tire pressure can extend the service life.

How to Use the Service Brake When Parking a Motor Vehicle on a Downhill Road?

When parking a motor vehicle on a downhill road, the service brake should be applied earlier than on a level road. When driving downhill, the vehicle's speed gradually increases due to gravity, resulting in a longer braking distance compared to a level road. Therefore, braking should be initiated earlier than on a level road. Conversely, when parking on an uphill road, braking should be delayed compared to a level road because the vehicle's speed naturally decreases due to the slope resistance, leading to a shorter braking distance. During normal driving, the service brake (foot brake) is commonly used to slow down or stop the vehicle while moving. Once the vehicle comes to a complete stop, the parking brake (hand brake) should be engaged to prevent the vehicle from rolling forward or backward.

What are the symptoms of no engine oil?

Symptoms of no engine oil: The oil light on the dashboard will illuminate, the water temperature will be high, the valves will make noise, and there will be knocking sounds in the engine. Continuing to drive without engine oil will significantly reduce lubrication effectiveness, and in severe cases, it can cause engine seizure due to lack of lubrication. The less oil there is, the more severe the consequences. When the engine is started again, dry or semi-dry friction will occur between the cylinder and piston, accelerating part wear. Additionally, the starting resistance will greatly increase, making it difficult to start. Engine oil is the lubricant for engine operation, providing lubrication, cleaning, cooling, sealing, and friction reduction. It plays a crucial role in reducing engine part wear and extending the engine's lifespan.

What engine does the Chevrolet DS7 come with?

The engine of the Chevrolet DS7 is produced by the Xiangyang Engine Plant of Dongfeng Peugeot Citroën Automobile Company Ltd. (DPCA), and it is a domestically manufactured engine. The engine model of the Chevrolet DS7 is EP6. The low-power version has a maximum power of 133kW, a maximum horsepower of 180, and a maximum torque of 250 Nm. The high-power version has a maximum power of 158kW, a maximum torque of 215 Nm, and a maximum horsepower of 300. Here are some daily maintenance methods for the Chevrolet DS7 engine: Use lubricating oil of the appropriate quality grade. For gasoline engines, choose SD--SF grade gasoline engine oil based on the additional devices in the intake and exhaust systems and usage conditions; for diesel engines, select CB--CD grade diesel engine oil according to the mechanical load, with the selection standard not lower than the manufacturer's requirements. Regularly change the engine oil and filter. The quality of any grade of lubricating oil will change during use. After a certain mileage, its performance deteriorates, which can cause various problems for the engine. To avoid malfunctions, change the oil regularly based on usage conditions and maintain an appropriate oil level. When oil passes through the fine pores of the filter, solid particles and viscous substances in the oil accumulate in the filter. If the filter becomes clogged and oil cannot pass through the filter element, it may rupture the filter element or open the safety valve, allowing oil to bypass through the bypass valve and carry contaminants back to the lubrication areas, accelerating engine wear and increasing internal pollution. Regularly clean the crankcase. During engine operation, high-pressure unburned gases, acids, moisture, sulfur, and nitrogen oxides from the combustion chamber enter the crankcase through the gap between the piston rings and cylinder walls, mixing with metal powder from component wear to form sludge. In small amounts, it remains suspended in the oil; in large amounts, it precipitates out, clogging filters and oil passages, making engine lubrication difficult and causing wear. Regularly use a radiator cleaner to clean the radiator. Removing rust and scale not only ensures the engine operates normally but also extends the overall lifespan of the radiator and engine.

Is it necessary to buy car seat cushions?

It is necessary to buy car seat cushions as they can reduce wear and tear, prolonging the lifespan of the original seats. Some car owners also purchase seat cushions for aesthetic reasons, especially if the original seats are made of fabric, which is prone to getting dirty. Other passengers may accidentally stain or damage the seats, so seat cushions can also provide warmth in winter, coolness in summer, and are easier to clean. Car seat cushion maintenance tips: 1. Avoid prolonged exposure to sunlight, as it can cause the leather to fade; 2. Regularly clean and maintain the cushions. Use a vacuum cleaner weekly to remove dust and a professional leather soft cleaner for cleaning. After cleaning, do not use a hair dryer to quickly dry the leather; let it air dry naturally. 3. If you choose fabric seat cushions, they can be either dry-cleaned or hand-washed. When hand-washing, use a low-alkaline detergent and soak them in 30-degree warm water for 10 minutes before washing. Do not machine wash or wring them out.
