Which is better, SP or SN grade engine oil?

Whether it is SP or SN grade engine oil, they are both API certified standards. Although the best choice is the oil that best suits your vehicle, SN grade oil is the latest standard introduced. Theoretically, SP grade oil is better than SN grade oil, with superior performance. Here is some information about API: 1. API grades are as follows: There are currently 13 types of S-series engine oils, namely SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, SN, and SP. According to the alphabetical order, the oil represented by a later letter is superior to that represented by an earlier letter. 2. API certification standards: API is the abbreviation for the American Petroleum Institute, which is responsible for setting standards. Engine oils that meet API certification standards will bear the API certification mark.

What is the function of car front fog lights?

Here is an introduction to the functions of car front fog lights: 1. In foggy or rainy conditions where visibility is significantly affected by weather, they allow other vehicles to see your car. 2. Installed at the front of the car, slightly lower than the headlights, they are used to illuminate the road during rainy or foggy weather. 3. They can improve the visibility for the driver and other traffic participants, enabling oncoming vehicles and pedestrians to spot each other from a greater distance. Here are the operation methods for turning on the front and rear fog lights: 1. Lever-operated type: The fog lights are activated by rotating the switch on the lever. When the button marked with the fog light symbol is turned to the ON position, the front fog lights turn on. Then, turning the button downward to the rear fog light position activates both the front and rear fog lights simultaneously. 2. Button-operated type: For models where the front and rear fog lights are turned on via buttons, there are fog light buttons near the dashboard or center console. Pressing the front and rear fog light buttons respectively will illuminate the front and rear fog lights.

What is the function of tire hairs?

The function of tire hairs is to test the quality of the tire rubber by pulling them. Below is relevant information about tire hairs: 1. If they can be stretched long and are difficult to break, it indicates good rubber quality. Otherwise, it suggests poor rubber quality or expired products. 2. Tire hairs are formed during the vulcanization process of tires, where liquid rubber flows into the vent holes of the tire mold and hardens. Related information: 1. Tire hairs mainly occur when the vehicle is driven at high speeds, causing the tires to rotate rapidly. 2. The air inside the tire treads is compressed and then released, creating continuous "compression-release" noise. 3. The faster the speed and the heavier the vehicle, the louder the noise. At high speeds, the effect of tire hairs is negligible, so they do not increase tire noise.

What Causes the Inability to Add Refrigerant to a Car's Air Conditioning System?

Car air conditioning systems may fail to accept refrigerant primarily due to compressor malfunction or excessive internal pipeline pressure, preventing refrigerant injection. In such cases, it's necessary to visit a 4S dealership for diagnostics to pinpoint and repair the specific fault. Additional details regarding car AC refrigerant recharge are as follows: 1. Procedure for adding refrigerant: Begin with pressure testing, followed by pressure retention checks. Upon confirming no leaks and stable pressure, proceed with vacuum extraction before refrigerant charging. 2. Precautions during refrigerant charging: Always start the vehicle and activate the AC system before charging. Refrigerant should typically be introduced through the low-pressure port while ensuring the high-pressure gauge connection remains securely tightened.

What is the difference between Giti Tire 221 and 228?

Giti Tire 221 and 228 differ in their specifications. Below is an introduction to the differences between Giti 221 and 228: 1. Giti 221 tire specifications: 195/60r15. 2. Giti 228 tire specifications: 225/60r16. Below is an introduction to the functions of tires: 1. Support the entire weight of the vehicle and bear the load of the car. 2. Transmit traction and braking torque, ensuring the adhesion between the wheels and the road surface. 3. Reduce and absorb the vibrations and impact forces of the car during driving. Below is an introduction to tire maintenance methods: 1. Regularly clean the stones in the tire treads. 2. Reduce exposure of tires to direct sunlight. 3. Promptly check tire pressure. 4. Pay attention to suspension maintenance. 5. Regularly check front wheel alignment.

What is the difference between full slicks and semi-slicks?

The differences between full slick tires and semi-slick tires: 1. Price difference: Full slick tires are more expensive than semi-slick tires, which is hard to accept for amateur racing enthusiasts, who mostly choose semi-slick tires. 2. Grip difference: Full slick tires have stronger stickiness than semi-slick tires, providing better grip. However, if there are many debris like gravel on the road, these particles sticking to the tires can negatively affect grip. Therefore, full slick tires are not suitable for general road driving. 3. Sidewall hardness difference: Semi-slick tires have softer sidewalls than full slick tires, resulting in slower response at high speeds and deformation during emergency braking. Full slick tires are ultra-high-performance tires designed specifically for track use, requiring extremely high surface conditions. Once they reach working temperature, their grip is astonishing, far superior to semi-slick tires.
