Using counterfeit engine oil can lead to the following symptoms: rapid evaporation of coolant in the engine radiator, unstable idle speed, increased noise levels that escalate with higher speeds, excessive engine oil consumption, reduced vehicle power, sluggish acceleration, parking vibration, cylinder scoring, and increased carbon deposits. Engine oil, also known as motor oil or engine lubricant, is a substance enhanced with additives in a base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade viscosity index improvers. It is used for lubricating internal combustion engines. The main functions of engine oil are to reduce friction and wear on moving parts, remove sludge (one function of dispersants) and varnish (detergents) from the engine, neutralize acids produced by fuel and lubricant oxidation (detergents), improve piston ring sealing, and cool the engine by carrying away heat from moving components.

What does a cumulative score of 0 points on the 12123 driver's license mean?

A cumulative score of 0 points on the 12123 platform means that your driver's license has no accumulated penalty points, indicating no traffic violations or deductions, and that you have not incurred any point deductions during the current scoring cycle. Here are the key points to note after obtaining a new driver's license: 1. Probationary Period: The probationary period lasts for one year from the date of obtaining the license. During this period, certain restrictions apply. For instance, drivers on probation are not allowed to drive on highways unless accompanied by a licensed driver with at least 3 years of experience. For a C1 license, accumulating 12 points during the probationary period will result in immediate revocation of driving privileges. For larger vehicle licenses (B-class and above), accumulating 6-12 points (but less than 12) will extend the probationary period by one year, and the driver must retake the theoretical exam (Subject 1) within 30 days after the probationary period ends. 2. License Renewal: After the one-year probationary period, the license must be renewed at the issuing vehicle management office, provided there are no outstanding violations. After 6 years, the license must be renewed again at the issuing office, which requires a medical examination, along with the original license, ID card, and three 1-inch color photos to complete the application form. 3. Scoring Cycle: The scoring cycle for a driver's license is one year from the date of issuance. If a C1 license does not accumulate 12 points within this year and all violations are settled and fines paid before the next cycle begins, the points will be reset to 12 at the start of the new cycle.

Which lane to choose when there are three left-turn lanes?

When making a left turn with three lanes available, you should enter the leftmost lane. Here are some precautions regarding vehicle turns: 1. With traffic signals: At intersections with marked guide lanes, enter the guide lane according to your intended direction; yield to vehicles already in the intersection when preparing to enter a roundabout; when turning left, turn close to the left side of the intersection center point. Turn on your turn signal when turning, and use low beams when driving at night. 2. Without traffic signals: If there are traffic signs or markings, yield to the party with the right of way; if there are no traffic signs or markings, stop and look before entering the intersection, yielding to vehicles coming from the right; turning vehicles must yield to vehicles going straight; right-turning vehicles from the opposite direction must yield to left-turning vehicles.

What are the reasons for insufficient fuel supply in a car?

The reasons for insufficient fuel supply in a car include: 1. Incorrect valve timing. 2. Fuel pump: The fuel pump may operate poorly, short-circuit, or burn out due to internal or wiring issues, leading to inadequate or stopped fuel supply. 3. Blocked intake system: For example, the air filter may not allow proper combustion with the fuel. 4. Internal engine faults: Improper maintenance, abnormal wear, or issues with cylinder pressure may cause faults or potential hazards. 5. Blocked fuel system. 6. Spark plugs: Abnormal ignition, aging components, exceeding normal lifespan requiring replacement, carbon deposits, or incorrect model selection. 7. Poor ignition system performance: Such as issues with spark plugs or high-voltage wires.

How many years will it take for xenon bulbs to experience light decay?

Xenon bulbs generally experience reduced brightness after about 3 to 4 years and require replacement. Below are specific details about xenon lights: 1. Definition: Xenon lights (High-intensity-Discharge-Lamp) are high-pressure gas discharge lamps filled with a mixture of inert gases, including xenon, and do not have filaments like halogen lamps. They are also known as HID xenon lights, metal halide lamps, or xenon lamps, and are categorized into automotive xenon lights and outdoor lighting xenon lights. 2. Advantages: The color temperature of automotive xenon lights ranges between 4000K and 6000K, significantly higher than that of standard car headlight bulbs. They offer high brightness, with 4300K xenon lights emitting a white-yellow light. Due to the lower color temperature, the visual effect is slightly yellow, and the light penetration is stronger than that of higher color temperature lights, enhancing driving safety during nighttime and foggy conditions.

What to Do When a Car Tire Goes Flat?

If a tire goes flat and the vehicle has a spare tire, you can replace it and drive to a repair shop. If there is no spare tire, you can consider taking the flat tire to a repair shop for patching or calling a tow truck. Alternatively, you can call a mobile tire repair service. Below is relevant information: 1. Do Not Drive: A flat tire indicates low tire pressure, which increases the movement of various parts of the tire. Excessive rolling can cause abnormal heat buildup, reducing the performance of the tire's internal cords and rubber, leading to rubber delamination or cord breakage, excessive friction with the rim, and damage to the tire bead and abnormal wear. 2. Low Tire Pressure: Low tire pressure significantly increases friction between the tire and the ground, causing the tire temperature to rise sharply, the tire to soften, and its strength to decrease. Continuing to drive may risk a tire blowout.

Where is the oil dipstick located in the Audi Q5?

Audi Q5's oil dipstick can be found in the central control system. Turn on the ignition switch, press the CAR button, and select the oil level to check the oil quantity. The engine is the heart of a car, containing many metal surfaces that rub against each other during movement. These components operate at high speeds, in harsh environments, and can reach working temperatures of 400°C to 600°C. The Audi Q5 is a dynamic and versatile SUV, featuring the previous generation of Audi's family design. Its inverted trapezoidal grille uses large rectangular grids, and the headlights have a relatively square shape. The overall body lines are primarily rounded, exuding a strong sense of power.
