Excess engine oil needs to be drained out. Adding too much oil increases the engine's operating resistance, affects the vehicle's fuel consumption, increases engine noise, and raises the crankcase oil pressure. In severe cases, it can lead to oil burning. The following are the functions of engine oil: 1. Friction reduction: A sufficiently thick oil film separates the surfaces of relatively sliding parts, thereby reducing wear. 2. Sealing: Engine oil can form a seal between the piston rings and the piston, reducing gas leakage and preventing external contaminants from entering. 3. Anti-rust: Lubricating oil adheres to the surface of parts, preventing contact with water, air, acidic substances, and harmful gases. 4. Cushioning: When the pressure in the engine cylinder rises sharply, suddenly increasing the load on the piston, piston skirt, connecting rod, and crankshaft bearings, this load is transmitted and lubricated through the bearings, cushioning the impact load. 5. Cleaning: Good engine oil can carry carbon deposits, sludge, and worn metal particles from engine parts back to the oil tank through circulation, washing away dirt generated on the working surfaces of the parts through the flow of the lubricating oil.

Can you shift directly from 4th to 2nd gear?

You cannot shift directly from 4th to 2nd gear. Here are some precautions regarding car driving: Gear shifting: Automatic transmission vehicles have protection and interlock mechanisms for gear shifting. Accidentally shifting from D to R or P gear while driving can be dangerous, but you can freely switch between D and N gears, including while the vehicle is in motion. Avoid coasting in neutral: Coasting in neutral with an automatic transmission does not save fuel. Prolonged coasting in neutral can lead to insufficient oil pressure in the hydraulic lines of the automatic transmission, increasing friction, reducing lubrication effectiveness, and damaging the friction plates inside the automatic transmission.

What Does Running a Red Light Mean?

Running a red light refers to the act of a motor vehicle violating the prohibition of passage during the red light phase at signal-controlled intersections or road sections, crossing the stop line and continuing to move forward. The behavior of running a red light is clearly defined in the "Road Traffic Safety Law." Article 26 states that traffic signals consist of red, green, and yellow lights. A red light indicates prohibition of passage, a green light permits passage, and a yellow light serves as a warning. A red light is a traffic signal prohibiting passage. If a vehicle passes through an intersection during a red light, it constitutes the traffic violation of running a red light. Three photos captured by electronic cameras are used to determine whether a vehicle has run a red light: a photo of the vehicle crossing the stop line at the intersection, showing the red light and license plate number; a photo of the vehicle fully crossing the stop line, showing the red light and license plate number; and a photo of the vehicle continuing to move forward, comparing changes in the vehicle's position, showing the red light and license plate number. If these three photos are captured, the vehicle is determined to have run a red light. To avoid running a red light, follow these guidelines: First, observe the arrow signal, then the circular signal: Currently, there are two types of traffic signals: arrow traffic lights and circular traffic lights. When an arrow signal is present, first check the arrow signal and then the circular signal to avoid running a red light. Note: When encountering a circular red light, right turns are permitted. However, if the right-turn arrow signal is red, right turns are prohibited. Violating this rule will result in penalties for running a red light. Brake promptly: When the red light turns on, ensure the front of the vehicle does not cross the stop line. If the front wheels accidentally cross, and the rear wheels follow, the electronic camera will capture the violation, leading to penalties for running a red light. If the front wheels have just crossed the stop line when the signal turns red, passage through the intersection is prohibited. Wait for the green light before proceeding. Check the countdown on the green light before proceeding: When the green light flashes, if there is a countdown, use it to judge whether to proceed. If there is no countdown, and the vehicle is close to the intersection with high speed, it may pass to avoid running a red light due to delayed braking. If the speed is slow and the vehicle is far from the intersection, brake immediately to avoid running a red light. Article 38 of the "Regulations for the Implementation of the Road Traffic Safety Law of the People's Republic of China" states the following regarding motor vehicle and non-motor vehicle signals: When the green light is on, vehicles are permitted to pass, but turning vehicles must not obstruct the passage of straight-moving vehicles or pedestrians. When the yellow light is on, vehicles that have already crossed the stop line may continue to pass. When the red light is on, vehicles are prohibited from passing. At intersections without non-motor vehicle or pedestrian signals, non-motor vehicles and pedestrians must follow the motor vehicle signals. When the red light is on, right-turning vehicles may pass, provided they do not obstruct the passage of other vehicles or pedestrians. Running a red light is not considered a violation under the following circumstances: Yielding to emergency vehicles: Yielding to ambulances, fire trucks, or other emergency vehicles. If captured by surveillance cameras while yielding, the violation will not be recorded during manual review. Even if recorded, the driver may appeal to the traffic police department. Extreme weather: When visibility is so low that even electronic police cannot clearly see the traffic signals, the evidence of violation may be blurry. In such cases, mistakenly running a red light will not result in penalties. Emergencies: When transporting a critically ill patient to the hospital, running multiple red lights may be unavoidable. After delivering the patient, the driver can present proof from the hospital or the rescued individual to the traffic police for verification. If confirmed, the violation records will be cleared. If possible, calling an ambulance is recommended to avoid accidents caused by running red lights. Police direction: During peak hours, traffic police may temporarily direct traffic at major intersections. Drivers must follow the hand signals of the traffic police.

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.
