Why Does Volvo Use 0w20 Engine Oil?

What Are the Effects of Leaving a Car Unused for a Long Time?

Oil seal aging, battery premature failure, tire deformation, engine failure, oil oxidation corroding mechanical parts, etc. The damage to a car left unused for a long time is as follows: 1. Oil seal aging: If a car is left unused for a long time, the contact force around the oil seal will become uneven, and the direction with greater force will experience more deformation of the oil seal. The longer the car remains stationary, the harder it is for the deformation to recover, eventually leading to permanent deformation of the oil seal, which can easily cause oil leakage. 2. Battery premature failure: The car battery charges while the vehicle is in motion. If the car is left unused for a month, the battery may be harmed and could lose all its charge within that month. For older vehicles, the battery might die within 2-3 weeks. More seriously, long-term self-discharge of the battery can lead to the formation of sulfides on the electrode plates, affecting the battery's recharging efficiency and ultimately causing premature battery failure. 3. Tire deformation: When a car is stationary, the weight is borne by the parts of the four tires in contact with the ground, causing these contact areas to compress and deform. The longer the car remains unused, the harder it is for the deformed areas to recover, altering the weight distribution around the tires and creating uneven rolling radii, leading to tire imbalance. Once the car enters high-speed driving, body vibrations may occur, accelerating tire wear and posing safety risks. 4. Engine failure: If a car is left unused for a long time, the engine oil can deteriorate. Without timely replacement, the lubrication and wear levels will be compromised, affecting engine performance. Besides engine oil, prolonged parking can also cause issues with coolant, antifreeze, etc., ultimately leading to engine failure. 5. Oil oxidation corroding mechanical parts: When a car is left unused for an extended period, oil oxidation becomes severe. Oxidized oil not only loses its lubricating effectiveness but also produces acidic substances that can corrode mechanical parts. The longer the car remains stationary, the worse the deterioration becomes. When the engine is restarted, dry or semi-dry friction may occur between the cylinders and pistons, accelerating part wear and significantly increasing startup resistance, making it difficult to start the engine.

How Often Should Car Window Tint Be Replaced?

Replace it approximately every 3 years. The replacement of car window tint depends on the degree of wear. Generally, it takes about 3 years. Most car window glass in the Chinese market is just ordinary glass or coated glass, with UV blocking rates of 19% and 37% respectively. More extended information is as follows: 1. Use tint film to compensate for the shortcomings of the car windows themselves: Car glass alone cannot meet the daily needs of heat insulation and UV protection, which is why tint film is used to improve the inherent deficiencies of car windows. Even for more expensive imported cars, whether to achieve good heat insulation and UV protection effects or to ensure a healthy driving life for yourself and your family, it is best to apply a layer of car window tint. 2. The functions of car window tint: It refers to the film applied to the surface of car glass, commonly known as explosion-proof film. In addition to heat and light insulation, it also has explosion-proof functions. High-quality explosion-proof film uses special polyester film as the base material, which itself has strong toughness and is combined with special pressure-sensitive adhesive. In case of an accident, the glass will crack but remain adhered by the film, preventing shards from flying and causing injury. Car explosion-proof film also has one-way visibility and reduces glare. Since its introduction, car window tint has gone through four stages: dyed film, metal reflective film, heat-absorbing film, and intelligent spectral selection film.

How long is the service life of the DQ381 transmission?

DQ381 is a wet 7-speed dual-clutch transmission under Volkswagen's DSG series, featuring advantages such as high transmission efficiency, fast gear shifting, and improved fuel economy. The service life of this transmission is greatly influenced by personal driving habits and can generally last for more than 20 years. More details are as follows: 1. Automatic transmissions: These include AT transmissions, CVT transmissions, and DCT dual-clutch transmissions. Due to their advantages in cost and technology, dual-clutch transmissions are increasingly being used. Dual-clutch transmissions are divided into dry and wet types, with the difference lying in the working environment of the clutch plates. 2. Wet clutch plates: These are immersed in the transmission fluid, which helps with heat dissipation, making them more stable in operation. 3. Dry clutch plates: These are in direct contact with the engine flywheel, leading to poor heat dissipation. In congested urban areas, they are prone to overheating and even burning, making them more susceptible to failure. Wet dual-clutch transmissions have a more complex structure, higher manufacturing costs, and slightly lower transmission efficiency compared to dry types.

What is the solution for fault code U0100?

It is caused by the loss of communication with the Engine Control Module (ECM)/Powertrain Control Module (PCM) A. It is necessary to check whether the power supply to the engine computer is normal. It is best to go to a repair shop for a detailed inspection before troubleshooting. More related information is as follows: 1. Fault code U0100 applies to all car manufacturers: It means Lost Communication With Engine Control Module (ECM)/Powertrain Control Module (PCM) A. 2. Car fault code: It is the fault code reflected by the car computer ECU after the car has a fault. Generally, fault codes are caused by sensor faults or poor sensor performance, but some mechanical faults cannot be read by the ECU. When a car engine fails, the detection computer will display the fault code after detection. Through this code, maintenance personnel can accurately find the faulty part and then repair it. 3. Car fault codes can be divided into two types: One is an intermittent fault. The other is an actual fault. Usually, intermittent faults can be cleared as long as they do not appear again, but actual faults must be repaired before they can be cleared.
