What is the difference between API-SN and SP?

The differences between API-SN and SP are as follows: 1. Grade: SN is the second grade of gasoline engine oil, while SP is currently the highest grade of gasoline engine oil. 2. Oil film: The oil film of SN is relatively weak, while the oil film of SP is relatively strong. 3. Protection performance: The protection performance of SN is average, while the protection performance of SP is relatively strong. Here is some extended information about the specific introduction of engine oil quality grades: 1. API grade: API is the abbreviation of the American Petroleum Institute, and the API grade represents the quality grade of engine oil. 2. Engine oil level: SP-grade engine oil, as the highest grade of engine oil, is generally classified as fully synthetic oil. Semi-synthetic oil is mainly of SL and SM grades, and there are also SN grades.

Is it correct that ABS shortens braking distance?

Incorrect. ABS stands for Anti-lock Braking System, which prevents the wheels from locking up during emergency braking, thereby avoiding loss of steering control and potential hazards. Essentially, ABS achieves this by intermittently applying and releasing the brakes—tightening, releasing, tightening again, and releasing again. This allows the vehicle to maintain steering control during emergency braking, enabling the driver to avoid obstacles and reduce risks. Consequently, ABS tends to increase the braking distance. Here are some related details: 1. Single-channel ABS: Single-channel ABS typically controls both rear wheels based on the low-select principle. It does not fully utilize the grip of both rear wheels, so the braking distance may not be significantly reduced. 2. Wide application: Additionally, since the front wheels are not controlled, they may still lock up during braking, which does not improve steering control. However, the rear wheels will not lock up, significantly enhancing directional stability during braking—a major safety advantage. Due to its simple structure and low cost, single-channel ABS is widely used in light trucks.

What are the skills for reverse parking?

In the Subject 2 driving test, reverse parking requires two maneuvers: left reverse parking and right reverse parking. The details are as follows: 1. Right reverse parking: The driver observes the parking space through the right rear window. When the black edge of the right rear window aligns with the right boundary line of the parking space, the driver should turn the steering wheel steadily to the right to its limit. After the car enters the parking space, the driver should look back at the left rearview mirror. When the entire left boundary line of the parking space appears, the driver should immediately straighten the steering wheel. When the left door handle is level with the bottom line of the parking space as seen in the left rearview mirror, the driver should stop immediately. 2. Left reverse parking: The driver should focus on observing the left rearview mirror and adjust the direction to reverse the car into the parking space. After the car enters the parking space, the driver should observe the right rearview mirror. When the entire right boundary line of the parking space appears, the driver should immediately straighten the steering wheel. The driver should then shift their gaze to the left rearview mirror. When the left door handle is level with the bottom line of the parking space, the driver should stop immediately.

Do I Need to Empty the Tank When Switching from 92 to 95?

When switching from 92 to 95, the tank should be emptied. Although both 92 and 95 octane gasoline use the same base oil, the proportion of anti-knock agents differs. Mixing them can lead to engine knocking, insufficient power, carbon buildup, and other issues. Here are detailed explanations: 1. Explanation one: With equal amounts of 92 and 95 octane gasoline, the mass of sediment produced by both grades shows no significant difference, indicating that higher octane gasoline does not produce less carbon buildup than lower octane gasoline. 2. Explanation two: Manufacturers determine the fuel grade based on China's fuel quality and road conditions through testing and practical experiments.
