Can You Still Drive When the Oil Life is Below 5%?

You can continue driving when the oil life is below 5%, but it is recommended to visit a maintenance facility for servicing as soon as possible. At this stage, the performance of the engine oil begins to degrade, and its lubrication effectiveness diminishes. Oil life nearing zero does not mean there is no oil left; rather, it serves as a reminder for the owner to perform maintenance. If you wish to adhere to the recommended mileage for oil changes, you can reset the oil life indicator, which will then start counting from 100% again. Key Factors to Consider When Choosing Engine Oil: Engine oil selection should be based on the requirements of the engine. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher demands. Precautions for Changing Engine Oil: Always warm up the engine before draining the oil. This ensures the oil is thinner and flows more easily, helping to carry away impurities and drain the oil thoroughly. Avoid draining oil when the engine is cold. Additionally, replace the oil filter simultaneously, as an old filter may be clogged with debris, slowing oil flow and reducing engine lubrication. When refilling oil, ensure the correct quantity—some vehicles allow oil level checks via the dipstick to confirm proper levels. Functions of Engine Oil: The primary role of engine oil is lubrication. Over time, the oil is gradually consumed, and impurities or deposits may form, affecting lubrication efficiency. Oil also has a cleaning function, though some residues may remain in the engine. Its anti-corrosion properties are crucial—while oil cannot prevent oxidation entirely, it significantly reduces it. Good sealing enhances mechanical efficiency, but prolonged oil use may lead to chemical reactions that weaken sealing. Cooling is another function of oil, though extended use diminishes its cooling effectiveness.

Can the original 700 tires be replaced with 750 ones?

The original 700 tires can be replaced with 750 ones. Changing from 700 to 750 tires can improve the vehicle's load-bearing performance. From a load-bearing perspective alone, it is more reasonable to use 700 tires for the front wheels and 750 tires for the rear wheels. However, attention should be paid to the rim model to see if it can accommodate 750 tires. If the rim cross-section is too narrow for 750 tires, it is best not to replace them. The rim specification codes are basically in line with international standards. 4.50Ex16 indicates a one-piece rim with a nominal width of 4.5 inches and a rim code of E. 6.5-20 represents a multi-piece flat-base wide rim with a nominal width of 6.5 inches and a nominal diameter of 20 inches. In use, the rim specifications of the car are very important. The international standard tire code expresses the section height and aspect ratio as a percentage in millimeters, followed by the tire type code, rim diameter (in inches), load index (allowable load mass code), and allowable vehicle speed code.

Is it necessary to file a record with the vehicle management office for installing fog lights?

Installing fog lights does not require filing a record with the vehicle management office. Adding fog lights to a car is not an illegal act, nor does it require applying for a change of registration with the local vehicle management office. However, modifications such as changing the body color or replacing the engine require a change of registration. Below is a detailed introduction to the national regulations on vehicle modifications: Consequences of privately installing fog lights: If fog lights are added to a car without prior approval from the traffic management department, the vehicle may not pass the annual inspection. Applying for a change of registration: According to the relevant provisions of the current "Motor Vehicle Registration Regulations," any changes to the body color, model, performance, purpose, or structure of a licensed motor vehicle, or the replacement of the frame, body, or engine, must be reported to the vehicle management office for a change of registration. Modifications such as adding spoilers, extensive body kits, or altering the exhaust system are generally not permitted. Cases where a change of registration will not be processed: Changing the brand, model, or engine type of the motor vehicle, except for engines that are permitted by the national motor vehicle product authority; altering the registered appearance and technical data of the motor vehicle, unless otherwise stipulated by laws, regulations, or national mandatory standards.

Can the Old Logo of the Same Car Model Be Changed to the New Logo?

It is not allowed to replace the old car logo with a new one. Unauthorized logo replacement is illegal and will fail the annual vehicle inspection. Changing the car logo violates the "Motor Vehicle Management Regulations," as the logo must match the vehicle model and cannot be altered. If discovered, penalties will be imposed according to national regulations on motor vehicle safety technical conditions. Anyone who manufactures, sells, or uses trademarks without permission infringes on the trademark holder's exclusive rights, violating the Trademark Law. Therefore, even though logo replacement is a personal act by the car owner, it remains illegal. The "Automobile External Identification Management Measures" issued by the National Development and Reform Commission have officially come into effect. From now on, whether it's a domestic brand or a joint-venture brand, only vehicles with Chinese logos are permitted to drive on Chinese roads. Replacing the logo, especially changing the original Chinese logo to an English one, clearly violates the relevant regulations.

Does Comprehensive Car Insurance Cover Flood Damage?

Comprehensive vehicle insurance does not include flood damage coverage. Below is relevant information about comprehensive car insurance: Introduction: Comprehensive insurance typically refers to compulsory traffic insurance, vehicle damage insurance, third-party liability insurance, no-deductible coverage, passenger insurance, glass insurance, theft insurance, etc. Flood damage insurance is a newly derived type of auto insurance, which mainly refers to an additional coverage that car owners purchase for their engines. Notes: After purchasing flood damage insurance, if the vehicle is submerged, it is advisable for the car owner to proactively turn off the engine in water to avoid damage to engine components such as valves due to water impact while driving. While ensuring personal safety, immediately call the insurance company to report the incident and have them assess the damage on-site, or arrange for a rescue vehicle to transport the car to the insurance company's assessment center. If the damage falls within the coverage scope of the flood damage insurance, corresponding compensation can be obtained.
