Do Pearl White and Polar White Look the Same?

Pearl White and Polar White look different. Pearl White is a metallic paint, which is more expensive to repair later but has very high brightness and is quite beautiful; while Polar White is an ordinary white paint, easier to repair and at a lower cost. The differences between Pearl White and Polar White: Pearl White paint contains fluorescent powder, which reflects bright fluorescent particles under sunlight, whereas Polar White does not have fluorescent powder. The paint is pure white from inside out and does not emit fluorescent particles under sunlight. Additionally, Pearl White is more costly than Polar White. Polar White is a standard paint, appearing pure white to the naked eye because it does not contain fluorescent powder, thus it does not reflect fluorescent particles under sunlight and is easier to maintain. In terms of cost, Pearl White paint is more expensive to formulate, mainly due to the labor-intensive process involved in repair, filling, spraying, and polishing, which requires multiple steps. Moreover, spraying Pearl White is more challenging, with high demands on paint thickness control and uniformity. Achieving a seamless repair without color differences requires advanced technical skills. On the other hand, white paint formulation is less complex, making it cheaper than Pearl White. White paint does not contain any reflective or brightening additives, relying solely on the outer clear coat for brightness, making it easier to care for and maintain.

Can a new car go on the highway after running-in for 1000 kilometers?

A new car can go on the highway after running-in for 1000 kilometers. However, the speed should not exceed 100km/h. Still, it is necessary to pay a little attention, after all, the car needs a certain running-in period, and the first 1000 kilometers are still relatively critical. Definition of highway: Highway refers to high-level speed, compared to medium speed and low speed. In an environment where low speed is dominant, low speed is ordinary speed or normal speed, while in an environment where medium speed is dominant, medium speed is ordinary speed or normal speed. Precautions for driving on the highway: When driving on the highway, it is necessary to maintain a safe distance from the vehicle in front. When the speed is above 100km/h, keep a distance of more than 100 meters. There are distance confirmation signs on the highway, through which the distance can be confirmed. Stay away from trucks; when driving at high speed, do not drive side by side with trucks, nor follow behind trucks, try to overtake them. Keep driving in the middle lane; the leftmost lane on the highway is the overtaking lane, and large trucks are generally in the rightmost lane.

What Happens If You Overfill Engine Oil?

Overfilling engine oil can lead to increased fuel consumption, reduced power output, failure to meet environmental standards, shortened oil seal lifespan, and may cause engine oil leaks. The consequences of excessive oil addition are detrimental. Excess oil increases the crankshaft's rotational resistance, reduces engine output power, and the surplus oil may enter the combustion chamber, leading to oil burning, blue smoke emission, and consequently increased fuel consumption. The primary functions of engine oil are to reduce friction and wear between moving parts, remove sludge (one of the dispersant's roles) and varnish (cleaner's role) from the engine, neutralize acids produced from fuel and lubricant oxidation (cleaner's role), improve piston ring sealing, and cool the engine by carrying away heat from moving components.

How to Identify Tire Pressure Markings on Tires?

Tire pressure markings can be found on the sidewall of the tire. These markings indicate the maximum allowable pressure, not the recommended pressure. For example, a common marking might be '340 kPa,' which translates to 3.4 bar. According to national standards, tire sidewalls must display the production number, manufacturer's trademark, size specifications, load rating, maximum load and corresponding pressure, ply composition code (in Chinese Pinyin), installation requirements, and directional indicators. Strictly speaking, tire pressure refers to the air pressure inside the tire—essentially the 'blood pressure' of a car. The level of tire pressure plays a crucial role in a vehicle's performance and power.

Do I need to drive the car for a four-year vehicle inspection?

Four-year vehicle inspection does not require driving the car. Here are the details about the four-year vehicle inspection: 1. Specific explanation: Whether you need to drive the car for a four-year vehicle inspection depends on the type of vehicle. If it is a family-owned seven-seat small car, from the date of purchase to the fourth year, you do not need to drive the car for inspection. You only need to take the vehicle license and the compulsory traffic insurance policy valid for the current year to the vehicle management office to receive the free annual inspection sticker and environmental protection sticker. 2. Notes: The annual inspection sticker and green environmental protection sticker for exempt vehicles are free of charge, but a copy of the vehicle license is required for each when collecting them, so prepare in advance.
