What is the fuel tank capacity of the Volkswagen Touareg?

Volkswagen Touareg has a fuel tank capacity of 90 liters, which is the officially announced data. The recommended fuel grade for Volkswagen Touareg is 95, with a fuel consumption of 8.7 to 10L per 100 kilometers. A full tank can cover a distance of 900 to 1034km. During daily driving, it is necessary to pay attention to the remaining fuel level in the tank at all times. Generally, the fuel level is observed through the fuel gauge inside the vehicle. If there are no other issues, the fuel level will be accurately reflected on the gauge. The fuel gauge typically has 5 to 6 segments. It is advisable to refuel when there are 2 segments left to avoid running out of fuel midway. In actual refueling, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity marked by the car manufacturer is from the bottom of the tank to the safe limit, and there is still some space from the safe limit to the tank opening. This space is reserved to allow for fuel expansion when the temperature rises, preventing overflow from the tank. If fuel is filled up to the tank opening during refueling, the actual refueling amount may exceed the calibrated tank capacity.

How Many Kilograms is a 200-Liter Barrel of Engine Oil?

A 200-liter barrel of engine oil weighs approximately 174 kg to 182 kg. Different engine oils have varying densities, hence their weights differ. Therefore, the weight of a 200-liter barrel of engine oil depends on the oil's density. Generally, 1 liter of engine oil weighs between 0.87 kg to 0.91 kg. Here is some related information about automotive engine oil: Importance: Engine oil is crucial for the engine. Inside the engine, it not only lubricates but also cleans, seals, cushions, prevents rust, and dissipates heat. Working Principle: When the engine is running, the oil forms a thin film on the surfaces of various engine components, preventing direct contact and friction between them. Regular Replacement Needed: Over time, the performance of engine oil degrades, so it needs to be replaced regularly. Prolonged use without replacement can accelerate engine wear. The viscosity of engine oil changes with temperature, so it's important to pay attention to its performance under both low and high temperatures. For example, in 5W-30, the first number indicates low-temperature fluidity—5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, resulting in smoother cold starts for the car. The latter number represents the oil's kinematic viscosity at 100°C. A higher number indicates better ability to maintain viscosity at high temperatures, which can also be understood as better lubrication performance under high-temperature conditions.

Can You Drive Someone Else's Car Without a Vehicle License?

You can drive someone else's car without a vehicle license. The vehicle license is equivalent to the 'ID card' of a car, and every vehicle has one. A car without a vehicle license is considered an unregistered vehicle. If the car is not yours, you naturally won't have its vehicle license. Here is some additional information: License Proof: A driver's license is a kind of 'license proof.' It proves that you have the necessary skills to drive safely on the road. With a driver's license, you can drive motor vehicles of the corresponding type. As long as the other person's car has a vehicle license, you can drive it legally. Relevant Regulations: Article 12: Under any of the following circumstances, an applicant shall not be issued a motor vehicle driver's license: having organic heart disease, epilepsy, Meniere's disease, vertigo, hysteria, Parkinson's disease, mental illness, dementia, or other neurological diseases that affect limb movement and hinder safe driving; addiction to narcotics or psychotropic substances that has not been cured; revocation of a motor vehicle driver's license within the past two years; or fleeing the scene after causing a traffic accident, resulting in the revocation of the driver's license.

How far can an electric vehicle travel after a 20-minute fast charge?

Fast charging power varies, but generally speaking, a 20-minute fast charge can provide enough power for a ride of approximately five to eight kilometers. Here is some additional information: Precautions: If the battery is in a 100% discharged state, charging for half an hour will only replenish about 8% of the battery's capacity, allowing for only 8% of the total mileage. It is not recommended to use the battery in such an excessively undercharged state, as it can have adverse effects on the battery. For a 100% discharged battery, the charging time typically ranges from 8 to 10 hours to fully recharge. Ways to avoid power-consuming riding: When riding an electric vehicle, avoid sudden acceleration and hard braking. These two riding behaviors are typical examples of aggressive driving, which not only pose safety hazards but also significantly harm the battery. Therefore, it is best to avoid such riding habits. It is advisable to use manual assistance when starting an electric vehicle. Starting an electric vehicle is actually a power-intensive situation. Since electric bicycles are equipped with pedal functions, combining manual assistance with electric power during startup can make the battery last longer.

What is the Best Material for Spark Plugs?

Spark plugs made of platinum and iridium are considered the best materials. Components of a Spark Plug: A spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. Types of Spark Plugs: The main types of spark plugs include: standard spark plugs, projected insulator spark plugs, electrode-type spark plugs, seat-type spark plugs, pole-type spark plugs, and surface-gap spark plugs. Working Principle of Spark Plugs: Under high voltage, the air between the center electrode and side electrode of the spark plug rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties and forming a discharge channel in the gap, resulting in a "breakdown" phenomenon. At this point, the gas becomes a luminous body, known as a "spark." Along with thermal expansion, a "crackling" sound is also produced. The temperature of this electric spark can reach as high as 2000-3000°C, which is sufficient to ignite the air-fuel mixture in the engine's combustion chamber.

At what mileage should fuel additives start to be used?

Fuel additives should start to be used at 20,000 kilometers. Mileage for using fuel additives: Fuel additives are unnecessary for new vehicles with less than 20,000 kilometers. For vehicles exceeding 20,000 kilometers, they should be added as needed, typically one small bottle per tank of fuel. Long-term use of fuel additives can be harmful to the engine. Excessive use can increase carbon deposits in the combustion chamber, and prolonged overuse may even lead to engine knocking, detonation, and worsened vehicle emissions. Precautions for using fuel additives: New vehicles are not recommended to add fuel additives because they haven't been driven much, and their operating conditions are usually good, with no serious carbon deposits, so additives are unnecessary. Frequent use of fuel additives is not advisable, as it can lead to oil sludge and gum formation, increasing carbon deposits in the combustion chamber. They should be added based on the vehicle's usage. For severe carbon deposits, manual cleaning is still required; fuel additives are not a miracle solution. For vehicles with severe carbon deposits, manual treatment is necessary, as fuel additives cannot completely remove them. For older vehicles, the oil filter should be cleaned or replaced before adding fuel additives. Use fuel additives cautiously and add them reasonably according to the vehicle's condition.
