What is the difference between Mobil Silver and Mobil Gold?

Mobil Silver and Mobil Gold have the following main differences: 1. Different properties: Mobil Gold is the top-tier engine oil of Mobil 1, with a relatively newer formula, belonging to the 6th generation; Mobil Silver belongs to the 5th generation formula, with average performance, significantly inferior to Mobil Gold. 2. Different grades: Mobil Silver has viscosity grades of 5w-30, 5w-40, and 5W-50; Mobil Gold only has one viscosity grade, 0W-40. 3. Different quality: Mobil Gold uses Group IV PAO fully synthetic base oil, with better anti-wear protection and low-temperature performance in additive formulation compared to Mobil Silver; many grades of Mobil Silver use MSDW hydroisomerized oil, commonly referred to as Group III+, which is no longer fully synthetic oil in the true sense.

Should Car Tires Be Replaced in Pairs?

As long as the wear difference between the two tires is not significant, generally replacing a single tire is acceptable. If the old tire has been used for less than one year and the tread depth difference with the new tire is within 2mm, replacement in pairs is unnecessary. For old tires used between 1-3 years with a tread depth difference of 2-4mm, selective replacement can be considered. For old tires used over 3 years with a tread depth difference exceeding 4mm, it is recommended to replace them together. Below is relevant information about tires: 1. Under normal circumstances, the service life of a tire is approximately 70,000 kilometers. Theoretically, the tread wear on both sides of the car should be consistent during driving. If only one side is replaced, it may result in uneven tread wear between the left and right tires. 2. The main functions of tire treads are to enhance grip, reduce noise, and improve water drainage. If the treads on both sides are uneven, the performance of the tires may deviate, potentially causing the old tire to skid or lose traction during poor road conditions or emergency braking. 3. The height difference in tires can affect the outer circumference of the wheels. If the left and right tires are inconsistent, it may cause the car to pull to one side due to the old tire.

Will holding a baby in the front passenger seat result in penalty points?

Holding a baby in the front passenger seat will not result in penalty points, but it will incur a fine. It is illegal to hold anyone in the front passenger seat. According to the Road Traffic Safety Law, children under the age of 12 are not allowed to sit in the front seat of a motor vehicle, and preschool children in the rear seats must use dedicated child seats as required. The regulations for front passenger seat occupancy are: 1. Minors aged 12 and above should not sit in the front passenger seat but can sit in the rear seats. If necessary, a child seat should be used with the seatbelt fastened, and the child safety lock on the rear door should be engaged. 2. Pregnant women should not sit in the front passenger seat, as the design of the seatbelt does not account for pregnancy. In the event of an accident, it is difficult to ensure the safety of the front passenger.

What Are the Causes of Car Failures?

Here are the causes of car failures: 1. Presence of vulnerable parts: It is impossible in car design to make all parts have the same lifespan, as some parts are inherently vulnerable. For example, components like air filter elements, spark plugs, and engine oil have relatively short lifespans and require regular replacement. Failure to replace them in time or premature damage can lead to car failures. 2. Quality differences in consumables: The main consumables in cars include fuel and lubricants. Poor quality of these additives can severely impact the car's performance and lifespan, making it more prone to failures. 3. Car usage environment: Cars are used outdoors and are greatly affected by environmental conditions. Highways, with their wide and flat surfaces, allow for high speeds but also increase the likelihood of failures and accidents. Uneven roads cause severe vibrations and jolts, leading to damage. Driving in mountainous areas consumes more power, and long waiting times in cities significantly alter the car's operating conditions. When the car cannot adapt, it becomes prone to failures or sudden breakdowns.

What are the signs that power steering fluid needs to be replaced?

The signs that power steering fluid needs to be replaced: when the color becomes cloudy and noticeably black, it indicates that the power steering fluid has quality issues or has been used for too long, and it needs to be replaced promptly. If you feel that the steering becomes heavier during normal driving, it may also be due to deteriorated power steering fluid, resulting in reduced steering assistance, and the power steering system needs to be checked. During regular use, you can check the fluid level to determine if there is a shortage. Normal power steering fluid is generally reddish and transparent. Automobile manufacturers do not strictly specify the replacement interval for power steering fluid, but it is generally recommended to replace it every 2 years or every 30,000 kilometers. Car owners can refer to this replacement interval or replace it based on the actual condition of the vehicle.

Are Traffic Violations Detected by Electronic Eyes Uploaded on Weekends?

Traffic violations detected by electronic eyes are not uploaded on weekends. Electronic eyes, also known as electronic police, are the common name for the intelligent traffic violation monitoring and management system. Electronic eyes utilize various technologies such as vehicle detection, photoelectric imaging, automatic control, network communication, and computer processing to monitor traffic violations around the clock. These violations include running red lights, driving in the wrong direction, speeding, crossing lines, and illegal parking. The system captures images and information of the violations and processes them afterward. Electronic eyes use induction loops to sense the pressure from vehicles on the road, collect signals through sensors, and send them to the central processor for temporary storage in registers.
