Adding fuel additives can have certain benefits. Fuel additives can help remove carbon deposits, improve atomization, reduce wear, protect the engine, and lower emissions, among other functions. The differences in fuel quality between domestic and international markets have led to the accumulation of carbon deposits in many vehicles over time. These deposits adhere to fuel injectors, fuel lines, and engine walls, causing various issues such as reduced power and abnormal engine vibrations. More details are as follows: 1. Many modern engines are direct-injection types, which require the use of fourth-generation cleaning additives. Using traditional or low-quality additives may lead to poor atomization in the fuel injectors, inadequate heat dissipation, and a tendency for engine knocking. Therefore, if you're unsure, it's better not to use them. 2. Additionally, the sales channels for fuel additives are mixed in quality. According to surveys, consumers primarily purchase fuel additives from 4S shops, gas stations, and e-commerce websites. The variety of fuel additives sold online is vast, with significant price differences, yet their functions are largely similar.

What are the causes of intermittent idling vibration in the Cruze?

The causes of intermittent idling vibration in the Cruze are: 1. Excessive carbon deposits inside the engine; 2. Issues with the ignition system; 3. Unstable oil pressure, causing the oil pump to fail to supply oil in time; 4. Insufficient cylinder pressure in the engine; 5. The additional air valve not opening or opening too little when the engine is cold; 6. Poor atomization or partial blockage of the fuel injector. Taking the 2018 manual Pioneer Edition Cruze as an example, its body dimensions are: length 4450mm, width 1807mm, height 1459mm, wheelbase 2700mm, fuel tank capacity 52 liters, and trunk capacity 290 liters.

How to prevent stalling when starting on a slope for Driving Test Subject 2?

To prevent stalling when starting on a slope for Driving Test Subject 2, follow these steps: 1. Engage first gear and press the accelerator until the tachometer reaches 1500 to 2000 RPM, then keep your right foot steady; 2. Slowly release the clutch to the semi-engagement point, then press it back slightly and keep your left foot steady, while quickly releasing the handbrake; 3. If you notice the car starting to roll backward after releasing the handbrake, gently release the clutch with your left foot and maintain the accelerator between 1500 to 2000 RPM. The time limits for Subject 2 are: 1. Reversing into a parking space must be completed within 210 seconds; 2. Parallel parking must be completed within 90 seconds; 3. After stopping on the slope for the hill start, you must start and move uphill within 30 seconds.

How long does it take for a car window tint to be usable?

For small cars, window tinting is generally ready for normal use after three days in summer, while in winter it may take seven days or even longer. Precautions after tinting: After car window tinting, try to avoid frequently rolling the windows up and down within three days. For newly tinted cars, the windows are usually tighter, and during the opening and closing process, the edges of the tint film are prone to wear and curling. The film, which hasn't fully adhered yet, is also susceptible to displacement, potentially damaging the car window tint. Ensure that within three days, when driving on highways, do not open the sunroof. Additionally, when parking the vehicle, choose a sunny location to ensure the moisture inside the tint film evaporates fully. If there are stains on the car window tint, never use sharp hard objects to scrape or harsh chemical solvents to wipe. It is recommended to gently clean with a clean damp towel, sponge, or soft cloth. Differences in film quality: Car window films are divided into two types: front window and rear window. The main difference lies in the light transmittance—the higher the transmittance, the brighter the interior. The front window film must have a light transmittance of 70% to comply with national legal standards, ensuring it does not affect the driver's all-weather visibility or the vehicle's safety performance. Rear window films come in two types: one is double-sided, meaning the view from inside to outside and outside to inside is the same. The other is single-sided, where the view from inside to outside is clear, but from outside to inside is mostly obscured. This type is safer and offers higher privacy.

How to Use the M Gear in an Automatic Transmission Car?

The method of using the M gear in an automatic transmission car is as follows: 1. When overtaking, it can utilize the high torque of lower gears to accelerate quickly, completing the overtaking action more swiftly; 2. When going downhill, it can make full use of engine braking to reduce speed; 3. When driving at high speeds, it allows for rapid acceleration and can use engine braking during emergency braking; 4. When taking curves, it can utilize engine braking to decelerate. The M gear refers to the manual mode of a semi-automatic transmission, which allows manual control of gear shifting (upshifting and downshifting). There is no need to press the brake or release the accelerator when using the M gear. The functions of the M gear are: 1. To obtain greater traction when overtaking; 2. To gain more power when climbing long slopes; 3. To use engine braking to control speed when descending long slopes, preventing brake overheating and thermal fade.

How to open the Volkswagen CC's sensor-activated trunk?

The method to open the Volkswagen CC's sensor-activated trunk is: Simply wave your foot under the sensor to open the trunk. A sensor-activated trunk means you don't need to use your hands to operate it when opening the trunk. The trunk is the car's storage compartment for miscellaneous items, increasing life convenience. Inside the trunk, you can find a spare tire, a vehicle first aid kit, a tool kit, a warning triangle, a fire extinguisher, and an emergency fuel tank lid release cable, among other things. Taking the 2021 Volkswagen CC as an example, it belongs to the mid-size car category with body dimensions of: length 4865mm, width 1870mm, height 1459mm, a wheelbase of 2841mm, a fuel tank capacity of 66 liters, and a trunk capacity of 501 liters.
