Where is the original production location of Castrol engine oil?

Castrol engine oil originates from the United Kingdom. Introduction to Castrol: Castrol engine oil has three major series: Castrol Edge, Castrol Magnatec, and Castrol GTX. Among them, Edge is claimed to be the most powerful engine oil in Castrol's product line. Castrol Edge utilizes advanced Titanium Fluid Technology, which enables the oil to become harder under extreme pressure, thereby reducing friction and metal separation. When the pressure decreases, the oil returns to its free-flowing state. Domestic production facilities: Castrol has multiple processing plants in China, with factories located in Harbin, Shenzhen, and other cities. These facilities process various engine oil products under the Castrol Lubricants company and distribute them nationwide.

Is there a purchase tax for the BMW 5 Series Hybrid in 2020?

As of May 31, 2020, BMW/MINI owners who purchase or exchange for a new BMW X5 plug-in hybrid will have the opportunity to enjoy exclusive additional financial benefits or insurance subsidies. Brand exchange purchases may also qualify for additional insurance subsidies. Introduction to Vehicle Purchase Tax: Vehicle Purchase Tax (Vehicle-purchase-tax) is a tax levied on entities and individuals purchasing specified vehicles within China. It evolved from the vehicle purchase surcharge and was implemented on January 1, 2001, under the "Vehicle Purchase Tax Law of the People's Republic of China." Purpose of Vehicle Purchase Tax: The Vehicle Purchase Tax is imposed on users of taxable vehicles at the consumption stage, better reflecting the principle of fairness. The principle of fairness aims to protect legal income, eliminate illegal income, regulate unreasonable income, and adjust excessive income. Therefore, the implementation of the Vehicle Purchase Tax can regulate excessive consumption expenditures. It also embodies the principle of tax-paying capacity, meaning higher-income individuals bear more tax, while lower-income individuals bear less. Those with higher consumption capacity contribute more tax than those with average consumption capacity.

Why is the BMW Z4 center control screen not lighting up?

If it happens occasionally, it is normal because when starting the car, the electricity is momentarily used for ignition, resulting in lower voltage. If the screen fails to light up multiple times during startup, you should check whether the power supply to the display screen is normal. If the power supply is abnormal, replace the power supply module. Then, check whether the ribbon cable connection is good. If there is a problem, replace the ribbon cable. If everything is normal, it may be that the display screen is damaged. Here are the specific details: 1. Restart the ignition: If the center control screen goes black and does not light up, you can first restart the ignition to reboot the screen. If the problem persists, it is likely due to poor line contact. You need to promptly check whether the lines have loose connections. If so, it will naturally cause the center control screen not to light up. In this case, simply reconnect the loose parts properly. 2. Aging signal line: It could also be due to aging of the power signal line. You can try replacing it with a new one. If the black screen issue is resolved, it confirms that the power signal line was indeed the problem. If the center control screen remains black after checking the above two scenarios, it is likely due to prolonged use of the screen, causing the power supply module to malfunction, leading not only to lag but also severe black screen issues.

Can You Still Drive with a Faulty Crankshaft Position Sensor?

Crankshaft position sensor damage means the car cannot be driven anymore. When the crankshaft sensor is damaged, the rotation angle of the crankshaft cannot be determined, and the vehicle's computer does not receive signals from the crankshaft position sensor. To protect the engine, it stops fuel injection and ignition. Principle of the Crankshaft Position Sensor: The crankshaft position sensor is usually installed at the front end of the crankshaft (near the pulley), the rear end near the flywheel, or the middle of the crankshaft. In early models, it was also installed inside the distributor. It is one of the most important sensors in the control system. Function of the Crankshaft Position Sensor: Its functions include detecting engine speed, hence it is also called a speed sensor; detecting the top dead center position of the piston, thus also known as a top dead center sensor, including detecting the top dead center signals of each cylinder for ignition control and the top dead center signal of the first cylinder for sequential fuel injection control.

How to Take a Photo for Vehicle License?

When taking a photo for the motor vehicle license, it should be shot from a 45° angle on the left front side of the vehicle. The vehicle image should occupy two-thirds of the photo; the vehicle photo should clearly show the body color and exterior features.

What grade of gasoline should the Lynk & Co 03 use?

The Lynk & Co 03 should use 95-octane gasoline, as recommended in the vehicle's official user manual. In addition to checking the appropriate gasoline grade in the user manual, you can also find it indicated on the fuel tank cap. Generally, the gasoline grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should use 92-octane gasoline, while those with a compression ratio between 10.0-11.5 should use 95-octane gasoline. If the compression ratio is higher, 98-octane gasoline is recommended. However, with the application of new technologies, the compression ratio alone cannot determine the appropriate gasoline grade. High compression ratio engines can also be tuned to use lower-octane gasoline, as factors like ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, higher-octane gasoline has a higher octane rating and better anti-knock properties. For example, 92-octane gasoline contains 92% isooctane and 8% n-heptane, while 95-octane gasoline contains 95% isooctane and 5% n-heptane. If the Lynk & Co 03 occasionally uses the wrong gasoline grade, simply switch back to the correct grade after the current tank is used up. However, prolonged use of the wrong gasoline grade can have the following effects: Using a higher-octane gasoline in a vehicle designed for lower-octane fuel won't cause damage, but the increased octane rating can alter the fuel's ignition point, leading to delayed combustion in the engine. This reduces the engine's power output and thermal efficiency, resulting in poorer performance. Using a lower-octane gasoline in a vehicle designed for higher-octane fuel can cause engine knocking. The significantly lower octane rating reduces the fuel's ignition point, causing premature ignition during the compression stroke. If combustion occurs before the spark plug fires, it creates resistance during the upward stroke, making the engine run very unstably. Mild knocking may only increase noise without significant engine damage, but severe knocking indicates serious engine issues, affecting driving stability and causing abnormal wear on pistons and cylinders, potentially leading to cylinder scoring.
