Under what circumstances is a touch-up pen suitable for use?

A touch-up pen is suitable for small, inconspicuous areas of scratches. Here are some details about touch-up pens: Color difference of touch-up pens: The touch-up pen may produce a color difference with your car's body color, making it look unattractive. It might be better to simply find a place to polish and wax, which could remove the scratch. The purpose of a touch-up pen is to cover exposed metal to prevent rust, and it can also repair regular scratches. However, the color will still differ significantly from the original car paint, so it should only be used temporarily. Characteristics of touch-up pens: Due to usage environment limitations, touch-up pens must have a quick-drying feature at room temperature; otherwise, they may cause dripping or attract dust, affecting appearance. Touch-up pens are formulated with standard colors and have a certain level of universality. However, they cannot perfectly match vehicles with varying degrees of aging, and the color difference may be more pronounced compared to custom-mixed spray paint.

What Causes an Automatic Transmission Car to Fail to Shift Gears?

Automatic transmission cars may fail to shift gears due to solenoid valve failure, gear lock malfunction, or battery issues. Below is a detailed explanation of the causes: Solenoid Valve Failure: If the solenoid valve in the automatic transmission fails or if there is a malfunction in the brake control system, the solenoid valve needs to be replaced. When the gear cannot be shifted, avoid forcing the gear lever. Gear Lock Engaged: Some automatic transmission vehicles are equipped with a gear lock switch, primarily used to force gear shifting when the car has no power or to prevent the vehicle from rolling. Accidentally activating this switch can lock the gear. Locate the "shiftlock" button to perform the unlocking operation. Battery Depletion: A depleted car battery can also prevent gear shifting. Check if the car's lights and dashboard are functioning normally. If they are not working properly, it indicates that the car's battery is depleted. Simply recharge the battery to resolve the issue.

Should the GSX250 use 92 or 95 octane fuel?

According to the official vehicle manual recommendation, the GSX250 should use 92 octane gasoline. In addition to checking the appropriate gasoline grade in the vehicle manual, the GSX250 can also be checked on the fuel tank cap, which will also be indicated. Usually, the fuel grade can also be determined based on the engine's compression ratio. Vehicles with an engine compression ratio between 8.6-9.9 should choose 92 octane gasoline, while those with a compression ratio between 10.0-11.5 should choose 95 octane gasoline. However, with the use of some new technologies, the gasoline grade cannot be determined solely by the compression ratio. A high compression ratio can also be tuned to use lower-grade gasoline. This is because, besides the compression ratio, other factors such as ignition timing, turbocharging technology, and Atkinson cycle technology also play a role. Generally, the higher the gasoline grade, the higher the octane number and the better the anti-knock performance. 92 octane gasoline contains 92% isooctane and 8% n-heptane, while 95 octane gasoline contains 95% isooctane and 5% n-heptane. If the GSX250 occasionally uses the wrong gasoline grade, simply switch back to the correct grade after use. However, long-term use of the wrong gasoline grade can have the following effects: For vehicles recommended for lower-grade gasoline, using higher-grade gasoline will not cause damage, but the increase in octane number will change the fuel's ignition point, leading to delayed combustion in the engine. This means the engine's power output and thermal efficiency will decrease, and the actual feedback experience is reduced performance. For vehicles recommended for higher-grade gasoline, using lower-grade gasoline can cause engine knocking. Because the octane number is too low, the gasoline's ignition point decreases, causing it to ignite prematurely during the compression stroke. If combustion occurs before the spark plug ignites during the compression stroke, resistance will occur during the upward stroke. This resistance will make the engine run very unstable. If the knocking is imperceptible, it only increases noise and does not significantly damage the engine. However, if there is noticeable knocking, it indicates the engine's condition is very severe. The vibration not only affects driving stability but can also cause abnormal wear on the pistons and cylinders, and in severe cases, cylinder scoring.

Is driving at 105 km/h considered speeding when the speed limit is 100 km/h on the highway?

Driving at 105 km/h when the speed limit is 100 km/h on the highway is considered speeding. Below is an introduction related to speeding on highways: Speeding: Driving at 105 km/h when the speed limit is 100 km/h constitutes a 5% over-speed. According to traffic regulations, this does not incur penalties, as the rules clearly state that a speed exceeding the limit by less than 10% results only in a warning. Therefore, a 5% over-speed will receive a warning but no points deduction or fine. Speedometer Measurement Introduction: Regarding speed measurement, the speedometer is required by regulation not to display a speed lower than the actual speed. As a result, car manufacturers adjust the displayed speed to be higher than the actual speed, typically by 3 to 14 km/h. Therefore, driving at 105 km/h may or may not be actual speeding, depending on the specific vehicle. It is advisable to rely on the speedometer as the benchmark—if the speedometer does not exceed the speed limit, the actual speed will also not exceed it. Additionally, the speed displayed by a radar detector ("electronic dog") or the vehicle's built-in navigation system may differ, but they generally follow the same principle as the speedometer.

Does Car Color Change Require Registration?

Whether a car color change requires registration depends on whether the altered color area exceeds 30%. According to Article 6 of Chapter 2 of the "Road Traffic Safety Law", if the color change area of a motor vehicle does not exceed 30%, no registration change is required. Conversely, if it exceeds 30%, registration is necessary, and it must be completed within 10 days after the color change. Precautions for vehicle color change: Before changing the color of a motor vehicle, it is necessary to consult the vehicle management office where the vehicle is registered to confirm whether the region permits color changes. If the region does not support this practice, registration cannot be processed after the color change, and the vehicle must be restored to its original color. Documents required for applying to change the body color of a motor vehicle: "Motor Vehicle Change Registration Application Form". Identity proofs and copies of the motor vehicle owner and agent. Motor vehicle registration certificate. Motor vehicle driving license. Clearance of all previous fines. Additionally, according to Article 10 of the "Motor Vehicle Registration Regulations", owners are no longer required to apply in advance to the vehicle management office. They can first change the vehicle color, install body kits, replace the engine, etc., and then apply for change registration with the vehicle management office. Furthermore, registered motor vehicles must apply for change registration with the local vehicle management office under the following circumstances: Change of body color. Replacement of the engine. Replacement of the body or frame. Whole vehicle replacement due to quality issues. Change of use nature, such as commercial vehicles converted to non-commercial use or vice versa. Change of the motor vehicle owner's residence in or out of the jurisdiction of the vehicle management office. Moreover, according to Article 15 of the "Road Traffic Safety Law of the People's Republic of China": Police cars, fire trucks, ambulances, and engineering rescue vehicles must be painted with designated patterns and equipped with alarms and signal lights as required. Other motor vehicles are prohibited from using similar patterns, alarms, or signal lights specific to these vehicles.
