Mechanical oil refers to ordinary quality lubricating oil obtained from petroleum lubricating oil distillates through dewaxing, solvent refining, and white clay processing. Mechanical oil can be divided into high-speed mechanical oil and ordinary mechanical oil, which are respectively used for lubricating textile machine spindles, ordinary machine tools, and other general equipment, classified by 50°C kinematic viscosity. The full name of mechanical oil is total loss system oil, which is suitable for various textile equipment, machine tools, hydraulic presses, small pneumatic equipment, sewing machines, small electric motors, ordinary instruments, wood processing equipment, lifting equipment, papermaking machinery, mining machinery, etc. It is also applied to transmissions of various light-load equipment operating below 60°C, manual oiling rotating parts of textile equipment, machine tools, small and medium-sized electric motors, fans, water pumps, and other equipment, as well as ordinary lubrication points such as bearings or ordinary lubrication systems. Most mechanical oils are not suitable for circulating lubrication systems.

I've been in the automotive industry for over a decade. Mechanical oil is essentially a specialized lubricant for machine components, and in our daily vehicle use, it most commonly refers to engine oil. It's not a single type of oil but encompasses a wide range, including mineral oil, synthetic oil, and more. Its primary functions are to reduce friction between parts, dissipate heat, prevent rust, and keep the engine running smoothly. If you neglect it, the oil will age and deteriorate, accumulating impurities, which can lead to increased noise, higher fuel consumption, and even damage to the engine. Nowadays, synthetic oil is popular in the market. Although it's more expensive, it's more durable and suitable for modern high-efficiency engines. I often advise new car owners to refer to the manual to choose the right viscosity, such as 5W-30, and to check and change the oil regularly every 5,000 kilometers. This can significantly extend the vehicle's lifespan and improve driving safety. Remember, don't underestimate this fluid—it's the heart protector of your car.

After helping others repair cars many times, I've learned that mechanical oil, commonly referred to as engine oil, primarily forms a protective film inside the engine to reduce friction and wear between pistons and cylinders, preventing overheating damage. If the oil quality is poor or forgotten to be replaced, engine performance can sharply decline. I've personally witnessed multiple major overhauls initiated by oil-related issues. Therefore, when selecting oil, pay attention to its grade and brand. Mineral oil is economical but requires replacement every six months, while synthetic oil lasts longer. During maintenance, don’t overlook cleaning the filter when changing the oil, as clogged oil passages can lead to bigger problems. Properly maintained engine oil can save fuel and ensure safety. Just develop a habit of regular checks and avoid cutting corners to save money, which could lead to hidden dangers.

Engine oil is a common lubricant used in various mechanical equipment to lubricate moving parts. In the automotive field, it typically refers to engine oil. Its functions include reducing friction, dissipating heat, and cleaning the interior of the engine. If not changed for a long time, it can accumulate dirt, reduce efficiency, and even damage the engine. When selecting, it's important to distinguish between mineral oil and synthetic oil, with the synthetic type being more durable and high-performance. Regular oil changes, such as every 5,000 kilometers or so, are key to maintenance, ensuring the engine runs healthily and driving safety.

After decades of driving, what I've learned most profoundly is that engine oil is like the lifeblood of a car—it keeps engine components such as pistons and bearings running smoothly while reducing wear. In my younger days, using low-quality mineral oil caused frequent car troubles. Now, after upgrading to synthetic oil, the engine runs quieter and delivers stronger power. If the oil warning light comes on while driving, indicating low oil pressure, you must pull over and check immediately. For oil changes and maintenance, it's best to rely on professional shops, ensuring the oil level is just right—not too little or too much. High-quality oil can significantly extend engine life. I learned the hard way from delayed oil changes when engine noise suddenly surged, but regular maintenance has since made things much smoother. These small details truly determine a car's longevity.

Engine oil has evolved significantly from traditional mineral types to today's high-tech synthetic oils, primarily used in automobiles to lubricate engine components, enhance efficiency, and reduce resistance. I recommend that car owners dynamically select oil based on their vehicle manual standards and avoid switching brands arbitrarily, as turbocharged engines require specific synthetic oils. Regular oil changes, such as every 6,000 kilometers or so, can reduce emissions, improve fuel economy, and protect the environment. A new trend is the growing popularity of low-viscosity oils, which provide a smooth driving experience and extend the overall lifespan of the vehicle. Maintaining good oil is an investment in the future of your beloved car.

Does a 6-year-old vehicle require on-site annual inspection?

6-year-old vehicles require on-site inspection. According to the Implementation Regulations of the Road Traffic Safety Law, motor vehicles that have been in use for six years must undergo on-site inspection procedures during the sixth year. This can be processed at the local vehicle management office or the traffic management department of the public security authority. The annual inspection of motor vehicles can be conducted up to three months in advance, which is considered normal. Below is an introduction to the contents of vehicle annual inspections: Passenger transport vehicles: Inspected once a year within the first 5 years; inspected every 6 months after exceeding 5 years. Trucks and large/medium-sized non-passenger transport vehicles: Inspected once a year within the first 10 years; inspected every 6 months after exceeding 10 years. Small and mini non-passenger transport vehicles: Inspected once every 2 years within the first 6 years; inspected once a year after exceeding 6 years; inspected every 6 months after exceeding 15 years. Motorcycles: Inspected once every 2 years within the first 4 years; inspected once a year after exceeding 4 years. Tractors and other motor vehicles: Inspected once a year. If an operational motor vehicle passes the safety technical inspection within the stipulated inspection period, it does not need to undergo repeated safety technical inspections. Vehicles exceeding the scrapping age: Cannot be transferred (sold or bought), but can continue to be used. For transactions, the vehicle's scrapping certificate (canceling the vehicle's record) can first be processed at the vehicle management office before proceeding with the transaction.

What does a stability control system malfunction mean?

Stability control system malfunction means there is an issue with the electronic stability control system; the indicator light displays the working status of the electronic stability control system, and its color is generally yellow. Stability control system malfunction: This indicates that the vehicle's stability control system is either turned off or malfunctioning. If the ESP OFF button on the vehicle is accidentally pressed, pressing it again briefly will reactivate the ESP. If the ESP OFF light is on due to a system malfunction, it is necessary to promptly conduct a repair. Solutions for stability control system malfunction: If the throttle actuator is stuck in the closed position, the ECM commands the throttle to open, but the actuator remains stuck. If the electronic throttle fuse is intact and the wiring harness is fine, test pins 1 and 2 for the throttle motor coil; if the resistance is abnormal, replace the throttle. If the stability control system shows an electronic control system malfunction, it is recommended to visit a repair shop to read the fault codes with a decoder and proceed with repairs. The ESP system consists of a control unit and various sensors: a steering sensor (monitoring the steering angle of the steering wheel), wheel sensors (monitoring the rotational speed of each wheel), a yaw sensor (monitoring the vehicle's rotation around the vertical axis), and a lateral acceleration sensor (monitoring the centrifugal force during turns).

Is It Illegal to Tow a Broken-Down Car with a Rope?

Towing a broken-down car with a rope is considered illegal, and any towing or pulling not performed by a rescue vehicle or tow truck will result in a fine. This is because towing requires a special mechanical vehicle license, and regular cars do not have the right to tow. If your car breaks down, you should call for a professional tow truck. Traffic police recommend that if your vehicle breaks down on the road, you should immediately contact a professional and licensed tow truck service. This ensures a quick resolution, saves time, and provides the safest towing service. If your vehicle becomes immobile due to a malfunction, the correct procedure is to stop immediately, turn on the hazard warning lights, and place a warning triangle in the direction of oncoming traffic. The distance for placing the warning triangle depends on the type of road—for example, on highways, it should be placed 150 meters behind the vehicle. Then, call for assistance and wait for the rescue vehicle. If the breakdown occurs at night, you should also turn on the width marker lights and tail lights.

What does the owner of a motor vehicle mean?

The owner of a motor vehicle refers to the legal possessor of the car, which can also be understood as the person who paid for the purchase of the vehicle. The owner has the rights to buy, sell, and dispose of the vehicle, and is also responsible for any safety incidents involving the car. Here is an introduction to vehicle ownership: When the driver and the owner are in a marital relationship. Since marital property is generally managed as joint property during the marriage, regardless of which party is registered as the owner or which party is the driver, the liability for accidents ultimately falls on the family. When the driver and the owner have a vehicle borrowing relationship: It is common for relatives or friends to borrow vehicles. However, if an accident occurs while the driver is using the borrowed vehicle, the driver is generally responsible for the corresponding liability for the traffic accident as determined by the accident report. The vehicle owner is not liable. When the driver and the owner have a vehicle rental relationship: This situation usually occurs between the user and owner of commercial vehicles such as taxis, or between individuals and car rental companies. For taxi drivers and owners who have clearly defined rental agreements, the use of the vehicle is based on the rental relationship.

What are the six levels of water-damaged vehicles?

Water-damaged vehicles are classified into six levels based on the height of water immersion: above the brake disc lower edge but below the vehicle floor; above the vehicle floor but below the seats; above the seats but below the instrument cluster; middle of the instrument cluster; above the instrument cluster but below the roof; and complete vehicle submersion. Below is an introduction to water-damaged vehicles: Precautions after a vehicle is water-damaged: If the engine stalls in deep water, do not attempt to restart it. Call for rescue and wait for assistance. Never restart the engine. If it has already been restarted, take the vehicle to a repair shop as soon as possible for inspection and early treatment to prevent further damage. If the engine has only ingested water vapor through the air filter, simply clean the air filter, throttle valve, and cylinder of any moisture. Classification of water-damaged vehicles based on immersion level: Water-damaged vehicles are broadly categorized into three types based on the immersion level: those with water level below the wheels, which can still be repaired for practical use; those with water level above the dashboard; and those with water level above the roof. The latter two are considered severely water-damaged, requiring costly repairs and posing significant potential risks even after repair.
