Castrol and Mobil each have their own characteristics, with different performance focuses. The differences between the two are as follows: 1. Castrol engine oil contains titanium particles, known as titanium fluid. Utilizing the adsorption properties of titanium particles, after each engine shutdown, a protective titanium film forms on the friction parts of the combustion chamber and pistons, achieving "protection before starting." Additionally, regular use of Castrol can help fill minor damages in the engine cylinders with titanium. 2. Mobil engine oil emphasizes long-lasting performance, meaning it has a longer oil change interval. This is because Mobil uses an exclusive polyalphaolefin (PAO) base oil, with neatly arranged molecules that provide excellent oxidation resistance and high-temperature performance. Its viscosity changes little, making it more suitable for long-term use. Furthermore, this brand offers good noise reduction. However, its drawback is that under high RPM conditions, the engine may experience insufficient power output.

Can I Change My Car's Engine Oil Myself?

If the car owner masters the method of changing the engine oil, they can perform the replacement themselves. Engine oil consists of two parts: base oil and additives. The base oil is the main component of lubricating oil, determining its fundamental properties, while additives are an important part of the lubricating oil. The primary functions of engine oil are lubrication, cleaning, heat dissipation, ensuring the normal operation of the engine, and extending its lifespan. Therefore, engine oil plays a crucial role in the proper functioning and longevity of the engine. The SAE viscosity classification for winter oils includes grades such as 0W, 5W, 10W, 15W, etc. The symbol 'W' stands for winter, and the smaller the number before 'W', the lower the low-temperature viscosity and the lower the applicable minimum temperature. The SAE viscosity classification for summer oils includes grades such as 20, 30, 40, 50, where a larger number indicates higher viscosity and a higher applicable maximum temperature.

What is the speed limit on the Shanghai-Shaanxi Expressway?

The speed limits vary on different sections of the Shanghai-Shaanxi Expressway. 1. On the section from the Shaanxi-Henan border to the provincial border mainline toll station, the speed limit for all vehicles is 80km/h. 2. On the section from the provincial border mainline toll station to the Jinsixia Service Area, the speed limit for passenger cars is 120km/h, while other motor vehicles are limited to 100km/h. 3. On the entire connecting line between the Fuyin Expressway and the Shanghai-Shaanxi Expressway, the speed limit for passenger cars is 100km/h, and other motor vehicles are limited to 80km/h. Here is additional information: 1. The speed limits for tunnels, tunnel clusters, interchange hubs, accident-prone sections, sections with restricted technical indicators, and sections affected by special weather conditions along the expressway are subject to the on-site speed limit signs. 2. Strict lane management is enforced for passenger and cargo vehicles, prohibiting large buses from driving in passenger car lanes and cargo vehicles from driving in passenger car and bus lanes.

Why Does a Car Battery Drain Even When Used Daily?

There are two main reasons why a car battery may drain even when the car is used daily, as analyzed below: 1. The battery itself has issues and cannot hold a charge; 2. The daily driving distance is short, and frequent starts occur, preventing the battery from fully charging while undergoing high-current discharge, leading to gradual drainage over time. Additional Information: Below are precautions for battery maintenance: 1. Avoid prolonged outdoor parking: Avoid leaving the car parked outdoors for extended periods. If long-term parking is necessary, remove the battery to prevent freezing damage. 2. Engine starting: In winter, car engines are harder to start. Each attempt should not exceed 5 seconds, with intervals of at least 15 seconds between attempts. If the car fails to start after multiple tries, check other aspects such as the circuit, ignition coil, or fuel system. Avoid continuous starting attempts, as this can cause the battery to over-discharge and burn out. 3. Charging issues: A battery left unused will slowly self-discharge and eventually become unusable. Therefore, start the car periodically to recharge the battery. 4. Regularly inspect battery components and connections: Clean the battery terminals periodically and apply specialized grease to protect the wiring harness.

How Long Does It Take to Receive a Notification for Speeding on the Highway?

Highway traffic violations are similar to general traffic violations, and it takes at least 3 days to check, with the latest not exceeding 13 working days. If it is an out-of-town violation, it may take 2-3 weeks to check. Out-of-town violations can be checked on illegal traffic violation query websites; then, you can inquire at the traffic police detachment's violation processing hall. If caught by an electronic eye, points will be deducted, and a fine will be imposed. Below is additional information: 1. Relevant regulations: There are regulations for speeding on highways. If the speeding speed does not exceed 10% of the speed limit, there will be no fine or point deduction, but once exceeded, points will be deducted. However, regardless of whether it reaches 10%, it is still considered speeding. 2. Determining speed based on the dashboard: When driving, speed is determined based on the dashboard speed. However, since the actual speed of the car is calculated based on a system inside the car and ABS, there may be deviations between the actual speed and the dashboard speed on different road sections. Generally, the actual speed is lower than the dashboard speed, which is a safety consideration in car design. Therefore, there is a 10% leniency during highway speed checks.

How to Pay Traffic Fines for a Vehicle Not Under Your Name?

The driver can choose to process the violation either at a traffic violation handling window or through the "Traffic Management 12123" app by registering a vehicle not under their name. After registration, they can handle traffic violations that occurred from the date of registration, which involve demerit points and a single fine not exceeding 200 yuan. There are two types of violations: 1. On-site violations: These refer to traffic fines issued on the spot by traffic police when a driver violates traffic regulations. For example, if a parking ticket is issued, this is an on-site violation. The owner can directly pay the fine at the bank specified on the ticket. 2. Non-on-site violations: Generally, these refer to violations captured by electronic surveillance, such as running a red light or speeding, where evidence is collected by traffic police. For such violations, they only need to be processed within one demerit point cycle.
