Here are the methods for selecting the right engine oil for your car: 1. Choose the appropriate viscosity: It is best to use multi-viscosity lubricating oil when selecting engine oil. Multi-viscosity lubricating oil (also known as multi-grade lubricating oil) has the properties of light oil at low temperatures and heavy oil at high temperatures. In scenarios where multi-grade oil is recommended, one type of multi-grade oil can replace multiple single-grade oils. 2. Choose engine oil based on the season: Although multi-grade oil can meet the needs of extremely cold and warm seasons as well as heavy-duty engines, especially for diesel engines that do not have difficulty starting in cold weather, it is usually recommended to use single-viscosity lubricating oil, which is beneficial for engine lubrication and extends the engine's service life.

After driving for over a decade, I believe choosing engine oil should start with the user manual—the viscosity grade recommended by the manufacturer, such as 5W-30, is the most reliable. I also consider climate factors: in northern winters, oils starting with 0W or 5W make cold starts easier, while in the south, 10W might work fine. Engine oils are categorized into mineral, semi-synthetic, and full synthetic—newer cars benefit from full synthetic for longevity, while older cars can save costs with mineral oil. Check the API standard for SN or SP ratings to ensure environmental and cleaning performance. Don’t just rely on brand reputation; check for a recent production date. Change the oil regularly every 5,000 to 10,000 kilometers without delay—this keeps the engine running longer and saves fuel costs. In short, always follow the manual and adapt to actual driving conditions for a simple and worry-free approach.

What to Do When All C1 Driving License Points Are Deducted?

If all points of a C1 driving license are deducted, the driver needs to go to the vehicle management office at the place where the license was issued or where the violation occurred for a 7-day training on road knowledge and retake the subject 1 exam. Only by passing the subject 1 exam can the points be cleared. Below is the full-point learning knowledge for driving licenses: 1. Two instances of 12-point deductions in one cycle: If a driver is penalized with 12-point deductions twice within one scoring cycle, they must take both the subject 1 and subject 3 exams, commonly known as the 'road test.' 2. Full-point learning cycle: The full-point learning cycle lasts 5 days, with sessions held every morning. The courses include topics such as road violation scoring and penalties, driver psychological qualities and traffic safety, and road traffic safety laws and regulations. After completing all the courses, the school will issue a 'Training Completion Certificate.'

Is it permissible to overtake from the right lane while driving?

Overtaking from the right lane while driving is not permitted. Below is an introduction regarding overtaking from the right: 1. Concept: A vehicle traveling in the same lane merges into the right lane, overtakes the vehicle ahead, and then merges back into the original lane. The key factor in determining whether this constitutes 'overtaking from the right' is the position where the vehicle changes lanes—if the vehicle changes lanes both before and after overtaking at a considerable distance from the vehicle ahead, then this act of overtaking from the right lane does not count as 'overtaking from the right.' 2. Criteria for judgment: The decisive factor in determining overtaking from the right lane is observing the complete maneuver of the overtaking vehicle: a vehicle traveling in the same lane merges into the right lane, overtakes the vehicle ahead, and then merges back into the original lane. In this process, the position where the vehicle changes lanes is crucial—if the vehicle merges back into the original lane both before and after overtaking at a significant distance from the overtaken vehicle, then this act of overtaking from the right lane cannot be considered 'overtaking from the right.' 3. Penalty standards: According to traffic laws, overtaking from the right while driving is prohibited. Those who overtake improperly will be penalized with 3 demerit points and a fine ranging from 20 to 200 yuan. Overtaking is allowed, but overtaking from the right is prohibited because it is a blind spot.

How to Calculate Safe Following Distance?

When a motor vehicle is driving on the highway at a speed exceeding 100 kilometers per hour, the safe following distance should be more than 100 meters. Below is relevant information about safe following distance: 1. Calculation of safe following distance: According to the "Road Traffic Safety Law of the People's Republic of China," when a motor vehicle is driving on the highway at a speed exceeding 100 kilometers per hour, the safe following distance should be more than 100 meters; when the speed is below 100 kilometers per hour, the minimum safe following distance should not be less than 50 meters. 2. Precautions: (1) Pay attention to the warning signs and auxiliary lines on the highway. When driving on the highway at a speed exceeding 100 kilometers per hour, maintain a safe distance of more than 200 meters from the vehicle in front in the same lane. (2) In adverse weather conditions such as fog, rain, snow, etc., it is essential to stay alert and increase the safe driving distance. When encountering low visibility conditions like fog, rain, snow, sandstorms, or hail, exercise extra caution, increase the following distance by more than double, and ensure to maintain a safe distance to prevent rear-end collisions.

Can a New Car Be Replaced If Problems Occur?

To replace a new car due to problems, it must be within the car's three-guarantee period and meet the conditions for return. When returning the car, usage compensation fees must be refunded. Below is an introduction to the replacement or return of a new car: 1. Compensation Fees: The calculation formula for reasonable usage compensation fees is: [(Car Price (yuan) × Mileage (km))/1000] × n. The usage compensation coefficient n is determined by the manufacturer based on factors such as the duration and condition of the car's use, ranging between 0.5% and 0.8%, and is clearly stated in the three-guarantee certificate. 2. Conditions for Returning the Car: The car can be returned if there is a failure in the steering system, braking system, body cracking, or fuel leakage. If serious safety performance faults are repaired twice without resolution or new serious safety performance faults occur. If the engine, transmission, or the same major component of the engine or transmission is replaced twice and still cannot function normally. If the same major component of the steering system, braking system, suspension system, front/rear axle, or body is replaced twice and still cannot function normally. 3. Conditions for Replacing the Car: The car can be replaced if the same fault is repaired more than five times. Within the three-guarantee validity period (the three-guarantee period is 2 years or 50,000 kilometers, whichever comes first), if the car's repair time accumulates to more than 35 days, or if repairs due to the same product quality issue accumulate to more than five times, the consumer can replace the car. Within 60 days from the date the seller issues the car purchase invoice or within 3,000 kilometers of mileage (whichever comes first).

What Causes the Engine Fault Yellow Light to Illuminate?

Engine fault yellow light illumination may be caused by sensor issues, maintenance problems, or engine component failures such as spark plug malfunction, ignition coil failure, fuel pump issues, or fuel line blockage. Below are two scenarios explaining the illumination of the engine fault yellow light: 1. Normal illumination: When the vehicle's power is turned on, the system performs a self-check. During this time, not only the engine yellow light but also other fault indicators will illuminate simultaneously before turning off, which is a normal process. 2. Abnormal illumination: If the engine fault yellow light remains on after starting the vehicle, this indicates that the ECU has detected a fault in the engine system, which is an abnormal condition.
