Is Waxing or Crystal Coating Better for a New Car?

Overall, crystal coating is superior to car waxing, with specific advantages outlined below: 1. From a process perspective, crystal coating involves more meticulous and stringent application procedures compared to waxing. The waxing process entails cleaning the car thoroughly, applying wax manually or mechanically, and then wiping off the excess wax after 3-5 minutes. In contrast, crystal coating requires preliminary cleaning, followed by clay bar treatment to remove surface contaminants and tar spots, polishing to eliminate oxidation layers and minor scratches, degreasing to thoroughly remove residual oils, and finally applying the crystal coating. 2. In terms of effectiveness, crystal coating provides more comprehensive protection for the car's paint. Waxing primarily offers shine enhancement and water repellency, being one of the earliest car care products. Crystal coating, however, is the leading mainstream maintenance product in the automotive care industry today. Beyond shine enhancement and water repellency, it also provides scratch resistance and protects against damage from bird droppings, tree sap, and acid rain. High-quality crystal coatings even offer varying degrees of oil and stain resistance. 3. Regarding protection duration, crystal coating lasts significantly longer than waxing. Car wax typically lasts about a month and gradually wears off with each wash, usually disappearing completely after 2-3 washes. Crystal coating, utilizing nano-level materials, adheres better to the paint, offering protection for 1-2 years.

After the procedures are completed, submit the vehicle file to the vehicle management office in the new location to handle the transfer-in process, and the license plate can be replaced. The following are the relevant materials: 1. When the owner handles the change and transfer-out process, they need to prepare the vehicle registration certificate, the original ID card of the owner, etc., and then go to the license plate issuance location to complete the process. The owner should obtain the change form, fill it out as required in duplicate, stamp it with the owner's seal, and attach a copy of their ID card. Submit the materials to the registration acceptance counter for review. If eligible, proceed to the inspection counter for vehicle consistency verification and safety performance testing. After the vehicle passes the inspection, go directly to the license and certificate management counter to return the old license plate, pay the fees, and wait to receive the file and temporary license plate. 2. After completing the vehicle change and transfer-out process, go to the vehicle management office in the new location to handle the transfer-in process. Before handling the transfer-in process, the owner should check if the vehicle has any violation records. If there are any, the transfer-in registration will not be processed. Carry the vehicle file that meets the transfer-in conditions, the original ID card of the owner, and the corresponding documents to the acceptance counter to verify whether the procedures are safe and valid. Fill out the approval form, and after the review is completed, go to the national tax department to replace the vehicle purchase tax receipt.

Can I take the driver's license test on Sunday?

Generally, there are no tests scheduled on weekends. While you can choose to practice driving on weekends, the actual test times are not available on those days. The results of learning to drive and taking the driver's license test are referred to as the Learning to Drive Certificate, which is valid for 3 years. All subjects must be completed within this three-year period; otherwise, the certificate will become invalid. The validity period of the Learning to Drive Certificate starts from the day of the Subject 1 test. Below is an introduction to the four subjects of the driver's license test: 1. Subject 1 is a theoretical test. 2. Subject 2 includes five mandatory test items: reversing into a parking space, parallel parking, stopping and starting on a slope, turning at a right angle, and driving along a curve. Some regions may have additional items. 3. Subject 3 is divided into a nighttime light simulation test and an actual road operation test. 4. Subject 4 is a safety and civility test.

What is the fuel consumption difference between 1.5L and 1.8L engines?

1.5L engines consume 6 to 7.5 liters per 100 kilometers, while 1.8L engines consume approximately 7 to 9.5 liters per 100 kilometers. Below is relevant information: 1. Calculation method: The actual method to calculate fuel consumption per 100 kilometers is: X/100=50/600, where X is the actual fuel consumption per 100 kilometers being sought, and the right side of the equation represents 50 liters of fuel consumed over 600 kilometers of driving. 2. Fuel consumption per 100 kilometers: This refers to the amount of fuel a vehicle consumes when driving 100 kilometers on the road at a certain speed. It is a theoretical indicator for vehicles. The fuel consumption per 100 kilometers is a value measured by manufacturers under objective conditions using a dynamometer installed on the vehicle's chassis, converted into speed parameters, and then calculated as the theoretical experimental fuel consumption data for the vehicle model when driven at specified speeds.

Is a Fire Extinguisher Required for Cars on Highways?

It is advisable for private cars to carry a fire extinguisher. Highway traffic police generally do not conduct special inspections on whether small vehicles are equipped with car fire extinguishers. However, for buses, tourist vehicles, school buses, and hazardous chemical transport vehicles, there is a focus on checking whether they are equipped with onboard fire extinguishers, warning triangles, and other equipment, and whether the fire extinguishers are expired. The types of onboard fire extinguishers are as follows: 1. Dry Powder Fire Extinguisher: The principle of this extinguisher is chemical suppression, which interrupts the chain reaction of combustion. It has a high fire extinguishing level, comprehensive functionality, and rapid extinguishing capability, with electrical insulation properties and good low-temperature performance, making it particularly suitable for use in factories, warehouses, and outdoor settings. The drawback is that dry powder extinguishing agents are not resistant to re-ignition, and users must undergo specialized technical training. Due to its price advantage, most vehicles are equipped with portable pressurized dry powder fire extinguishers. 2. Carbon Dioxide Fire Extinguisher: The extinguishing mechanism is suffocation, achieved by reducing the oxygen concentration around the burning material. Carbon dioxide, as a fire extinguishing agent, has good insulation properties. However, its disadvantages include a high extinguishing concentration, resulting in a low fire extinguishing level, making it suitable for use in relatively confined spaces. It has poor resistance to re-ignition, and carbon dioxide is a moderately toxic substance. When the concentration of carbon dioxide in the air reaches 2%, it can cause discomfort. 3. Aqueous Film Forming Foam Fire Extinguisher: The extinguishing mechanism is cooling and isolation, with a high fire extinguishing level and minimal water damage during use. It neither has the secondary pollution of dry powder nor the toxicity of carbon dioxide. However, the biggest drawback of domestically produced aqueous film forming foam extinguishing agents is their poor stability after dilution, making them unsuitable for long-term storage. For a practical fire extinguishing agent, storage stability is one of its most important performance indicators.
