How Long Can You Drive When Prompted to Check Engine Oil Level?

If the engine oil level warning light appears, you must not continue driving. At this time, you should add engine oil before resuming driving. Engine oil is referred to as the lifeblood of the engine. Without engine oil, the engine cannot operate normally. More relevant information is as follows: 1. The role of engine oil: Engine oil not only lubricates the engine but also cleans, seals, buffers, prevents rust, and dissipates heat. 2. Oil film formation: When the engine is running, engine oil forms a thin film on the surfaces of various engine components, preventing direct contact and friction between them. 3. Friction consequences: If engine components directly contact and cause friction, it will accelerate engine wear and may lead to overheating. 4. Purchasing engine oil and oil filters: Always choose genuine products from reputable brands and purchase them through official channels.

How to deal with alkaline powder on the negative terminal of a car battery?

If there is a lot of white powdery substance around the negative terminal of the battery, it indicates oxidation. Although it does not affect ignition, it can damage the battery over time. (Avoid using water; instead, use a non-conductive material.) After cleaning off the powder, apply grease and add a rubber cover. More relevant information is as follows: 1. Poor sealing of the battery negative terminal: The white powder on the negative terminal of a car battery, commonly known as efflorescence, is caused by poor sealing of the negative terminal, leading to leakage. Once the battery leaks, the situation will worsen, and its performance will decline. The leaked fluid can corrode the battery terminals, causing poor contact in newly installed batteries later on. Generally, replacing the battery might be a good option. 2. Car battery maintenance: Regularly clean dust, oil stains, white powder, and other contaminants that may cause leakage from the panel and terminals (i.e., the positive and negative poles). By frequently cleaning the battery, the terminals will not accumulate white acidic corrosion powder, and the battery's lifespan will be extended.

Can I install the vehicle license plate by myself?

You can install the vehicle license plate by yourself. The installation method is as follows: 1. Take out the license plate screws and insert them into the anti-theft caps while rotating; 2. Position the license plate correctly, align the screws with the four gaps on the bumper, and secure them with a cross screwdriver; 3. After tightening, cover the anti-theft caps and press them gently. License plates are plates hung on the front and rear of the vehicle, usually made of aluminum, sheet metal, plastic, or paper, engraved with the vehicle's registration number, registration region, or other relevant information. Their main function is to identify the vehicle's region of registration and to trace the vehicle's owner and registration details through the license plate.

What Causes Belt Squealing?

Because the belt slips on the generator, intense friction and vibration occur between the belt and the pulley, producing a noise at a certain frequency. The main reasons for belt slippage are belt looseness or aging. Factors that can cause belt looseness include improper adjustment of the belt tensioner or insufficient tensioner spring force. Below is extended information about the belt: 1. Solution: Adjust the tension of the belt tensioner; if ineffective, replace the tensioner. Belt aging mainly refers to the belt gradually hardening and losing elasticity over prolonged use, reducing friction with the pulley. In this case, the only solution is to replace the belt. 2. Adjustment: If the belt is too loose, it will slip and produce noise; if too tight, it increases the belt's transmission resistance and causes premature wear on the bearings of the driven generator, water pump, and air conditioning. Adjusting the generator belt to the proper tension is crucial.

Can a Car Battery Still Be Used After Getting Wet?

If a car battery is soaked in water and not treated promptly, it cannot be used. Although there is water inside the battery, it is different from ordinary water. The water inside a battery is usually distilled or high-purity water, which has very low conductivity and is essentially non-conductive. However, common water in daily life contains various metals and trace elements that conduct electricity, so water ingress can cause short circuits and other issues in the battery. More details are as follows: 1. Car battery discharge: This can lead to sulfation of the battery. If the discharge is severe, it may even render the battery unusable. Battery discharge refers to deep discharge, where the voltage drops below 10.50V, causing sulfuric acid to react with the lead plates to form lead sulfate. 2. If not recharged in time: Lead sulfate can crystallize. Over time, these crystals will not decompose during recharging, a condition known as battery sulfation. After a car battery discharges, it should be recharged immediately using a battery charger. If a regular charger fails to recharge the battery, a repair device with high-resistance repair must be used to raise the voltage above 10V for successful recharging.

What Are the Impacts of Having 6 Points Deducted from a Driver's License?

Having 6 points deducted from a driver's license only has impacts under specific circumstances. The details are as follows: 1. Points Accumulation: For drivers holding licenses for large buses, tractors, city buses, medium-sized buses, or large trucks, if they accumulate more than 6 points but less than 12 points during the one-year probation period, their probation period will be extended by one year. If they again accumulate more than 6 points but less than 12 points during the extended probation period, their driving qualification for the probationary vehicle type will be revoked. 2. Fines Situation: If a motor vehicle driver accumulates less than 12 points in a scoring cycle and has paid all the fines, the points will be cleared at the end of the scoring cycle; if there are still unpaid fines even though the points are less than 12, the points will be carried over to the next scoring cycle. 3. Traffic Accident Case Warning Education: For drivers with licenses for large buses, tractors, city buses, medium-sized buses, or large trucks, if they have points deducted in a scoring cycle, they must participate in at least three hours of study on road traffic safety laws and regulations, safe and civilized driving, emergency response, and other knowledge during the review, and receive traffic accident case warning education.
