10w40 can alleviate engine oil burning. Below are the relevant details about 10w40 engine oil: 1. Advantages of 10w40 engine oil: 10W40 engine oil has a higher viscosity, providing better protection at high temperatures. For 10W40 engine oil, it is more suitable for use in southern China where winters are not too cold. The low-temperature fluidity of 10W engine oil is sufficient to meet the engine's requirements, and the high viscosity of 40-grade oil is suitable for German cars, older vehicles, or engines. 10W40 engine oil is only suitable for vehicles with minor oil burning issues. For vehicles with severe oil burning, systematic inspection and more effective measures are required. 2. Vehicle models not suitable for 10w40 engine oil: For Japanese cars (Toyota, Honda, etc.), Korean cars (Kia, Hyundai), American cars (GM, Ford, etc.), and French cars, the manufacturer's manual specifies the use of 5W30. If 10w40 engine oil with higher viscosity is used instead of the manufacturer-specified 5w30, the vehicle's lifespan will be significantly shortened, fuel consumption will increase by more than 4%, and noise levels will also rise.

What does 'fully paid but not released from mortgage' mean?

Fully paid but not released from mortgage means the vehicle is still in a mortgaged status. Dealers mortgage their inventory vehicles to banks for financing purposes. If you purchase the vehicle in full payment, you can proceed to the bank to complete the release of mortgage after paying the money—this is actually handled by the dealer, though sometimes the owner may be asked to accompany. If you buy the car with a loan, the mortgage will only be released after the final payment is made. Below are the requirements for those who want to buy a car with a loan: 1. Age: The buyer must be at least 18 years old and a Chinese citizen with full civil capacity. 2. Assets: The buyer must have a relatively stable job and a steady income or possess assets that are easily liquidated to ensure timely repayment of the loan principal and interest. Easily liquidated assets generally refer to securities and gold/silver products. 3. Guarantee: Provide a guarantee recognized by the bank. If the buyer's household registration is not local, they must also provide joint liability guarantee. The bank does not accept the mortgaged vehicle purchased with the loan as collateral.

How to Practice Parallel Parking in Driving Test Subject 2?

Key points for practicing parallel parking in Driving Test Subject 2 are as follows: 1. Vehicle Alignment: Generally, parallel parking is the first item in the test. When entering the parallel parking area, first align the vehicle properly. Stop when your shoulder aligns with the ground control line to prevent crossing the line or failing to enter the parking space when reversing. 2. Front Wheels Crossing the Control Line: Ensure both front wheels have crossed the ground control line before stopping. The best method is to stop when your shoulder aligns with the control line to avoid stopping prematurely due to nervousness, which would result in failure. 3. Slow or Incorrect Steering: Some candidates get overly nervous during the test and may confuse steering directions, such as turning left when they should turn right for right-side parking. In such cases, quickly correct the mistake—there might still be a chance to recover. Be decisive when steering; hesitation could lead to failure. 4. Mastering the Clutch: The clutch is particularly crucial in Subject 2. Proper clutch control is more than half the battle. Learn to maintain the semi-engaged state: release slightly if too slow, press slightly if too fast.

What is the difference between MT and CVT?

MT and CVT both refer to types of automotive transmissions, with the difference being that MT stands for manual transmission, while CVT is an automatic transmission. Below are the relevant introductions about MT and CVT: 1. MT: MT requires the driver to manually shift the gear lever (commonly known as the "gear stick") to change the gear engagement position inside the transmission, altering the gear ratio to enable the car to change speed. Most passenger car manual transmissions are four or five-speed stepped gear transmissions, usually equipped with synchronizers for smoother shifting and reduced noise. When operating a manual transmission, the clutch must be depressed to move the gear lever. 2. CVT: The gear ratio of a CVT is not a series of discrete steps but a continuous range of values, for example, it can vary from 3.455 all the way down to 0.85. The structure of a CVT is simpler than that of a traditional transmission, with a smaller size. It does not have the multiple gear pairs of a manual transmission or the complex planetary gear sets of an automatic transmission. Instead, it primarily relies on the primary and secondary pulleys and a metal belt to achieve stepless changes in the gear ratio.

Can the ETC device still be used if it falls off?

No, the ETC device will become invalid if it is removed by itself, as the ETC device has an anti-tamper function. There is a small switch on the back of the ETC electronic tag, which will automatically turn off once it is peeled off from the windshield. Therefore, you must take the vehicle's registration certificate to the ETC service provider for reactivation. ETC charging principle: There will be one or more ETC lanes on the highway. Through the dedicated microwave short-range communication between the vehicle-mounted electronic tag installed on the windshield and the microwave antenna in the ETC lane of the toll station, the computer network technology is used to settle accounts with the bank in the background, achieving the purpose of paying road and bridge tolls without stopping at the toll station. All of this is based on the principle of passing first and deducting fees later. Benefits of installing ETC: Time-saving: Eliminates the hassle of waiting in line; Green and environmentally friendly: Green and low-carbon, vehicles pass through toll stations without stopping, reducing noise and exhaust emissions and minimizing pollution; Cost-saving: Saves costs, reduces the frequency of vehicle starts and brakes, lowers wear and fuel consumption, and users can also enjoy a 5% discount on toll fees; Improved efficiency: The theoretical efficiency of ETC lanes can be increased by 2-3 times, making traditional ETC faster, more advanced, and more high-tech. Compared to license plate payment, ETC technology is more mature and advantageous. More policy support: The State Council clearly stated in the "13th Five-Year Plan for the Development of a Modern Comprehensive Transportation System" that "by 2020, the interoperability of transportation smart cards in key city clusters will be basically achieved, and the proportion of vehicles equipped with ETC will be significantly increased." It also explicitly set the target of "achieving a 50% ETC usage rate for road passenger vehicles by 2020" in the main indicators of the "13th Five-Year" comprehensive transportation development. More future possibilities: In addition to continuously improving the convenience of ETC installation and usage and the ETC usage rate for passenger vehicles, efforts will also be made to promote the use of ETC for trucks in the future. The deep integration of the ETC system with vehicle-to-vehicle communication, vehicle-road coordination, and other smart transportation development directions will be explored to provide comprehensive travel services for car owners. This means more application scenarios will support ETC applications. Below are precautions for installing ETC: Do not obstruct the view; it is best to install it behind the rearview mirror: Many car models have a large rearward tilt angle of the windshield, resulting in a smaller driver's field of vision. If this is not considered during ETC installation, it will increase the driver's blind spot. Install it behind the rearview mirror on the right side to avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power, but generally, it does not need to be charged or have its battery replaced, as there is a solar panel on its back that can charge itself. Therefore, during installation, avoid the black areas on the windshield and do not place it where the solar panel is easily obstructed. Once installed, do not remove it arbitrarily: The button in the middle of the adhesive is an anti-tamper guide rod, connected to a switch below. After the electronic tag is installed, the windshield will press the anti-tamper guide rod in. If it is removed arbitrarily, the anti-tamper guide rod will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will need to go to an ETC service point to unlock it. This is designed to prevent multiple vehicles from sharing one device. Precautions for using ETC: The ETC transaction sensing range is 8 meters. To prevent the ETC device of the vehicle in front from malfunctioning, maintain a distance of more than 10 meters from the vehicle in front to avoid automatic sensing and paying for the vehicle in front. The recognition speed for ETC lane passage is 20 kilometers per hour. If the speed is too fast, the vehicle device information cannot be read, resulting in a failed fee deduction. When using a debit card bound to ETC, insufficient balance will also cause the fee deduction to fail.

How can beginners determine the position of tires while driving?

Beginners can determine the position of tires while driving through the following methods: 1. Use the nodes of the vehicle's wipers to judge the position of the wheels: However, this method is not suitable for all vehicle models, as the sizes of wipers vary among different models, and the driver's sitting posture also differs, which may lead to slight errors in judging the wheel position. 2. Use the vehicle's steering wheel to determine the position of the left-side wheels: Since the steering wheel in China is on the left side, it is easier to determine the position of the left front wheel. The extended straight line from the leftmost side of the steering wheel indicates the position of the left-side wheels. If it coincides with the road markings, it means the vehicle is driving on the line. 3. Use the emergency hazard light button switch in the vehicle: Nowadays, the switches for emergency hazard lights in many vehicles are designed in the middle of the center console. While driving, the extended line from the position of the hazard light switch can be used to determine the position of the right-side wheels.

What's the Difference Between 6-Speed and 5-Speed?

6-speed and 5-speed transmissions differ in terms of price, power, gear manufacturing, fuel consumption, and comfort. The specific differences are as follows: 1. Price Difference: 6-speed vehicles are generally more expensive than 5-speed ones, and their operation is more frequent and complex. Most importantly, many people feel that the highest gear in a 6-speed is often unnecessary, making it a waste of money. Therefore, choosing between a 5-speed or 6-speed largely depends on individual needs. 2. Power Difference: For vehicles of the same class to achieve the same power output, a 6-speed transmission requires slightly fewer rotations compared to a 5-speed. In other words, 6-speed vehicles tend to have slightly more power and smoother gear shifts. 3. Gear Manufacturing Difference: A 6-speed transmission has one more gear than a 5-speed, which means its gear manufacturing is more refined to accommodate the additional gear. 4. Fuel Consumption Difference: 6-speed transmissions offer more precise speed control with a narrower speed range, making them more fuel-efficient than 5-speed transmissions to some extent. 5. Comfort Difference: Due to their more refined manufacturing, 6-speed vehicles produce less noise inside the cabin, whereas 5-speed vehicles tend to have louder engine noise. As a result, 6-speed vehicles provide a more comfortable driving experience.
