I'm the kind of person who is particularly meticulous about car maintenance. Full synthetic oil isn't actually a single brand—it's a premium type of motor oil produced by several major brands, such as Mobil 1, Castrol EDGE, and Shell Helix Ultra. These brands all offer full synthetic oil products, which use synthetic base oils and additives to provide better engine protection, withstand high and low temperatures, and extend oil change intervals to around 10,000 kilometers. When choosing oil, I always check for API or ACEA certifications to ensure it matches my car's manual requirements. Due to the prevalence of counterfeit oils, I also recommend buying genuine products from authorized stores. Full synthetic oil is more expensive than mineral oil, but the reduced engine wear and fuel savings make it worth the cost.

How many points are deducted for exceeding the time limit on a hill start?

Exceeding the time limit on a hill start results in a deduction of 100 points. The deduction criteria for hill starts are as follows: 1. After the vehicle stops, if the front bumper of the car or the front axle of the motorcycle is not aligned with the pole line and exceeds 50 cm in either direction, it is considered a failure; 2. After the vehicle stops, if the front bumper of the car or the front axle of the motorcycle is not aligned with the pole line but does not exceed 50 cm in either direction, 10 points are deducted (previously 20 points); 3. After the vehicle stops, if the body of the vehicle is more than 30 cm away from the road edge line but does not exceed 50 cm, 10 points are deducted (previously 20 points); 4. After the vehicle stops, if the body of the vehicle is more than 50 cm away from the road edge line, 100 points are deducted; 5. After the vehicle starts, if the vehicle rolls back 10-30 cm, 10 points are deducted; 6. After the vehicle starts, if the vehicle rolls back more than 30 cm, it is considered a failure; 7. If the engine stalls once due to improper operation, 10 points are deducted; 8. After the vehicle stops, if it is not started within 30 seconds, it is considered a failure due to exceeding the time limit; 9. If the parking brake is not tightened after stopping, 10 points are deducted; 10. If the vehicle rides or presses on the solid road edge line while driving, it is considered a failure.

Which position should the safety headrest align with in Subject 4?

In Subject 4, the safety headrest should be aligned so that the middle of the headrest corresponds to the middle of the head when the head is resting on it. Below is relevant information about Subject 4: 1. Introduction: Subject 4, also known as the Subject 4 theoretical test or driver's theory test, is part of the assessment for obtaining a motor vehicle driver's license. Subject 4 separates the requirements for safe and civilized driving, safe driving skills under complex conditions, and emergency handling knowledge from the original Subject 1, placing them after the actual road driving test of "Subject 3" to further assess the candidate's level of traffic awareness. 2. Test Content: Requirements for safe and civilized driving operations, knowledge of safe driving under adverse weather and complex road conditions, methods for handling emergencies such as tire blowouts, and knowledge of post-accident procedures. There are no appointment restrictions for the safe and civilized driving theory test.

Meaning of violation codes: Traffic violation codes are encoding regulations established by the Ministry of Public Security for traffic violations committed by motor vehicles and pedestrians. 2. The first digit of the code: This is the behavior code, which includes numbers 1 to 5, 7, and 8. 1 indicates motor vehicle passage, 2 indicates non-motor vehicle passage, 3 indicates pedestrian or passenger passage, 4 indicates highway passage, 5 indicates other regulations, 7 indicates implementation rules of provinces, autonomous regions, or municipalities directly under the central government, and 8 indicates local regulations of cities (regions, autonomous prefectures, or leagues). 3. The second digit of the code: This is the penalty point classification code, which includes numbers 0, 1, 2, 3, 6, and 7. 0 indicates no points, 1 indicates 1 point, 2 indicates 2 points, 3 indicates 3 points, 6 indicates 6 points, and 7 indicates 12 points.

What is the correct method for installing license plate screws?

Here is an introduction to the method of installing license plate screws: 1. First, screw the screw rod into the screw hole at the license plate installation position to check if all the screw holes are basically normal. After inspecting the screw holes, pre-assemble each set of screws. From top to bottom, the order is usually the anti-theft cap of the screw rod and the washer. The hexagonal screw cap is mostly unnecessary. 2. Align the pre-drilled holes on the license plate with the screw holes at the car's license plate installation position, then screw in the first set of screws. Be careful not to tighten them too much; just enough to hold the license plate in place. After completing the installation of the other sets of screws, when all four screws (some cars can only install two screws) are screwed in and checked to be secure, use a screwdriver to tighten the small opening on the anti-theft cap. Slightly pry the opening a bit larger with the screwdriver, then snap the anti-theft cap into place. The installation is now complete.

What is the ground clearance of the 2017 CR-V?

The ground clearance of the Honda CR-V 2017 is 193mm when fully loaded and 208mm when unloaded. Below is a related introduction to the minimum ground clearance: 1. Minimum ground clearance size: The larger the minimum ground clearance, the stronger the vehicle's ability to pass obstacles or uneven ground, but the higher the center of gravity, which reduces stability; the smaller the minimum ground clearance, the weaker the vehicle's ability to pass obstacles or uneven ground, but the lower the center of gravity, which can increase stability. 2. Factors to consider: The minimum ground clearance must consider the passability of loading and unloading platforms during transportation, and the possibility that the car will not scrape when approaching the edge of a general sidewalk. If the vehicle is intended for sale in a specific country or region, the quality of local roads must also be considered. At the same time, the value of the minimum ground clearance has certain limitations, as it is related to the vehicle's function and aerodynamics. For example, sports cars have a relatively small minimum ground clearance, while SUVs have a relatively large minimum ground clearance.

Should Tires with Cracks Be Replaced?

If there are minor cracks on car tires, the following methods can help determine whether the tires need replacement: 1. Outer edge wear; If you observe the outer edge of the tire in the direction of travel and notice significant wear, it indicates that the tire is frequently underinflated, meaning the pressure is insufficient. Inflate according to the "highway" standard, which is 30 kPa more than the normal standard. Note that underinflated tires are particularly unfavorable for driving in rainy conditions, as grip will noticeably weaken. 2. Convex and wavy wear; If you find that the contact part of the tire shows convex wear on both sides and the surrounding area exhibits wavy wear, it suggests that components such as the shock absorbers, bearings, and ball joints are severely worn. It is advisable to inspect the wear condition of the suspension system and replace any worn parts before changing the tires. 3. Uniform surface wear; Once the tread is worn out, it indicates that the tire's lifespan has ended, and replacement is necessary. Additionally, the tread plays a crucial role in dispersing water from the road surface, which is vital for maintaining the car's grip. If the wear has reached the standard tread depth (typically 1.6 mm for tires with a width less than 175 mm and 2 mm for wider tires), replacement is required. 4. Center wear; If severe wear is observed in the central area of the tire's contact part, it indicates that the tire is frequently overinflated. Be sure to check the accuracy of the pressure gauge and adjust the pressure accordingly. Note that overinflation is only necessary for high-speed or heavy-load driving.
