Engine oil is divided into winter and summer. Generally, winter engine oil has lower viscosity, while summer engine oil has higher viscosity. There is also all-season engine oil with moderate viscosity. Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties. Additives can compensate for and improve the shortcomings of the base oil's performance, giving it certain new properties, making them an important part of lubricating oil. The method for changing engine oil is: 1. Use a jack to lift the vehicle, locate the drain bolt, and unscrew it to drain the oil; 2. After removing the oil filter, place a container beneath it; 3. Replace with a new oil filter and add new engine oil.

What to Do If Your Driver's License Renewal Is Overdue?

If your driver's license renewal is overdue by less than one year, you can still renew it normally. If it has been overdue for more than one year but less than two years, your license will be locked, and you will need to retake one subject to restore it. If it has been overdue for more than three years, you will have to take all subjects of the driver's license exam, similar to applying for a new license. Upon passing, the cancellation will be lifted, or you can choose to reapply for a new driver's license. Additional Information: For a driver's license that has not yet expired, first confirm the expiration date, which is located in the lower left corner of the license and is easy to spot. Then, within 90 days before the expiration date, visit the vehicle management office to renew it. The documents required are the same as those for a license overdue by one year, with the only difference being that the vehicle owner can drive to the office themselves, primarily because the license is still valid at this time.

What is the method to deactivate the Focus anti-theft system?

To manually deactivate the Focus anti-theft system, insert the key into the ignition and turn it to the position where the indicator light comes on, then quickly turn it to OFF. Relevant information is as follows: 1. Composition: A typical electronic car anti-theft system contains an integrated chip with some switch gates. When an external trigger voltage is applied, the switch gates open and output a positive voltage to the driving circuit, which then activates the actuator and alarm circuit. The external voltage is applied via sensors or switches, ensuring concealment and resistance to tampering. 2. Principle: Electronically controlled cars usually come with a factory-installed anti-theft system, which operates on a similar principle to electronic anti-theft systems but with interconnected circuits, primarily designed to lock the engine system. Network-based anti-theft systems not only offer stronger functionality than electronic anti-theft systems but can also send theft alerts to the owner's mobile phone and have the capability to lock the engine system. Their mobile phone positioning feature can locate the vehicle within a certain range.
