What season is 20W50 engine oil suitable for?

The engine oil with the grade 20W50 is an all-season oil that can be used year-round, but it depends on the local winter and summer temperatures. However, such high-viscosity oil is rarely used in the market today, and most of this type of oil is semi-synthetic or mineral oil. Given the importance of engine oil to the engine, more and more people are pursuing fully synthetic oil and lower-viscosity oil. 20W50 oil can be used at a minimum temperature of -15°C, and its high-temperature viscosity of 50 can meet the engine's requirements in summer across China. Therefore, in southern China, 20W50 oil is considered all-season oil and can be used year-round. However, in northern China, it is not suitable for all seasons because winter temperatures there can drop below -15°C, which may cause issues like engine failure to start. Thus, this oil cannot be used in northern China during winter. Therefore, regarding the season for using 20W50 oil, it is suitable for summer across China, but in winter, it can only be used in southern China. In the viscosity grade, the number before 'W' represents the oil's viscosity in low-temperature conditions. The smaller the number, the better the fluidity and cold resistance. The number after 'W' indicates the oil's viscosity at 100°C, with a higher number representing higher viscosity and better high-temperature resistance. Apart from the numbers before and after 'W,' other parameters can also classify the oil. For example, 'S' at the beginning indicates oil for gasoline engines, 'C' for diesel engines, and the presence of both 'S' and 'C' means the oil is suitable for both gasoline and diesel engines. When selecting engine oil, consider the following: Choose oil based on the engine's requirements. There is no need to use overly advanced oil for engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. Multi-grade oil is preferable as it is economical, long-lasting, and efficient, providing better protection for the engine. Due to its characteristics, multi-grade oil may appear darker and have lower oil pressure than regular oil during use, which is normal.

How many points are deducted for making a U-turn over double solid lines?

Making a U-turn over solid lines is a traffic violation. According to Article 90 of the Road Traffic Safety Law, violators will be fined 200 yuan and receive 3 demerit points. Generally, on long roads, white solid lines are present in the middle sections or before intersections. If the lines are yellow dashed or white dashed, U-turns are allowed. However, U-turns are strictly prohibited over any solid lines. Permissible U-turn situations: Intersections with U-turn signs: If there is a clear U-turn sign at an intersection, U-turns are permitted. If there is a U-turn traffic light, follow its instructions. In the absence of a traffic light, U-turns can be made based on the specific situation, provided they do not obstruct other vehicles or pedestrians. Intersections without explicit no-U-turn or no-left-turn signs: U-turns are allowed if there are no signs explicitly prohibiting them. "No explicit prohibition" means the absence of "no U-turn," "no left-turn" signs, or solid lines in the center of the road. In such cases, U-turns can be safely made. Yellow grid lines also permit U-turns: Yellow grid lines are no-parking zones marked at intersections prone to congestion due to temporary stops, entrances/exits of important facilities, and other necessary locations. Parking on these lines (including waiting at traffic lights) is prohibited. Although stopping is not allowed in yellow grid zones, U-turns are permitted as long as there are no central barriers. Yellow grid lines without barriers are equivalent to "U-turn permitted." Intersections with U-turn traffic lights: This is straightforward—if there is a U-turn traffic light, proceed only when it is green. Simultaneous no-left-turn and U-turn permitted signs: U-turns are allowed, but left turns are prohibited. Note that "no U-turn" is not the same as "no left-turn." Precautions when making U-turns at intersections: Observe road markings. If solid lines are present, U-turns are prohibited under any circumstances. Continue driving to find a suitable location. If a "no left-turn" sign is present, U-turns are also prohibited at that intersection, even if there is no explicit "no U-turn" sign, as U-turns inherently involve a left turn. U-turns must be made from the innermost left-turn lane. U-turns are not allowed from the second left-turn lane. Always yield to oncoming traffic when making a U-turn. Ensure the maneuver does not interfere with straight-moving vehicles, or you will bear full responsibility for any accidents. Near intersection stop lines, lanes often have guiding arrows. The leftmost lane may not always have a left-turn arrow. If a straight arrow is present, U-turns are prohibited even without explicit "no U-turn" signs. U-turns must not be made on pedestrian crosswalks, as this is also a traffic violation.

What does vehicle kw mean?

Vehicle kw is the unit of power, and power is an important performance parameter of a car engine. Power is used to measure how much work the engine does per unit of time. The greater the power, the stronger the engine performance, but the higher the fuel consumption. Power is related to the engine's speed and torque. A simple way to increase engine power is turbocharging technology. Because turbocharging technology can solve the problem of insufficient air intake encountered by aircraft engines at high altitudes, it is widely used in gasoline and diesel engines of cars. Some luxury cars also use supercharging, whose principle is different from turbocharging.

Does the 2020 Civic Still Have the Oil Dilution Issue?

After comprehensive improvements, the 2020 Civic has not experienced the oil dilution issue. Here's an introduction to the oil dilution issue: 1. The oil dilution issue mainly refers to the phenomenon of oil level increase. 2. This phenomenon primarily occurs due to vehicle design reasons. Additional information: Oil level increase is caused by inherent design flaws in the vehicle. When driving continuously in low-temperature environments, the engine oil level may rise. If the oil level increases beyond a certain point, the engine malfunction indicator light will illuminate, potentially causing damage to the engine and posing safety risks.

How to Use Car Heater in Winter Without Fogging Up Windows?

Methods to prevent car windows from fogging up when using the heater in winter: 1. When turning on the heater, activate the car's external air circulation to allow outside air to enter the vehicle. This facilitates air exchange between the interior and exterior, reducing the temperature difference inside and outside the car, thereby preventing window fogging. 2. Apply anti-fog spray. This method involves spraying the anti-fog solution onto the glass and then wiping it clean, which helps in removing fog and dirt. Reasons for window fogging when using the heater: Due to the temperature difference between the inside and outside of the car, the warmer interior causes moisture to condense on the inner surface of the windshield, forming fog.
