What is the best location to install ETC?

For small cars, the ETC device is generally installed in the upper middle section of the front windshield, while for large vehicles such as trucks and buses, it is installed in the middle to lower section. The appropriate installation position should be no lower than 1.2 meters and no higher than 2.5 meters, with an installation angle between 30 to 90 degrees. For vehicles with factory-installed or aftermarket explosion-proof film, which may affect microwave communication signal transmission, the ETC should be installed in the microwave window area. ETC stands for Electronic Toll Collection system. To apply for ETC, the vehicle owner needs to provide original and photocopies of their valid ID card and vehicle registration certificate. If the application is handled by a non-owner, the agent's valid ID card is also required. The photocopy of the vehicle registration certificate should include the page with the most recent annual inspection stamp. A bank card for deducting highway tolls is needed, and the vehicle must be registered under an individual aged between 18 and 60. Documents required for official vehicles: An introduction letter from the vehicle owner (with official seal); Copy of the organization code certificate or business license (with official seal); Original ID card of the agent; Original vehicle registration certificate; The vehicle that needs ETC installation. Here are some precautions for ETC installation: Do not obstruct the driver's view. It is best to install it behind the rearview mirror: Many car models have windshields with a large rearward tilt angle, which reduces the driver's field of vision. Installing the ETC without considering this may increase blind spots. Installing it behind the rearview mirror on the right side can help avoid obstructing the view. Do not interfere with charging: The ETC electronic tag consumes power but generally does not require charging or battery replacement, as it has a built-in solar panel for self-charging. Therefore, avoid installing it on the blackened areas of the windshield or positions that may block the solar panel. Do not remove it arbitrarily once installed: The button in the middle of the adhesive is an anti-tamper lever connected to a switch. Once the electronic tag is installed, the windshield will press the anti-tamper lever in. If removed arbitrarily, the lever will pop out and trigger the switch, locking the electronic tag and rendering it unusable. You will then need to visit an ETC service point to unlock it. This mechanism is designed to prevent multiple vehicles from sharing one device.

What is SAE 10W-40 engine oil?

SAE 10W-40 is a fully synthetic engine oil, where SAE stands for the viscosity grade designation of the oil and is the abbreviation for the Society of Automotive Engineers. The "W" stands for Winter, and 10W indicates resistance to external low temperatures of -25°C. The smaller the number before the W, the better the oil's low-temperature fluidity, meaning it can be used in lower environmental temperatures and provides better engine protection during cold starts. The number after the W represents the oil's kinematic viscosity at 100°C, with 40 being the indicator of the oil's high-temperature resistance. Therefore, this is just one type of engine oil, and higher numbers indicate higher viscosity. Engine oil (Engine-oil) is the lubricant used by engines. It consists of base oil and additives. The density of engine oil is approximately 0.91×103 (kg/m3), and it serves functions such as lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion prevention, and shock absorption. It is often referred to as the "blood" of a car. Engine oils are classified as follows: Mineral oil: A commonly used lubricant on the market, it is derived from the distillation of petroleum to extract useful substances like gasoline and aviation fuel, followed by further processing of the remaining base oil. Semi-synthetic oil: Made from semi-synthetic base oil, it is a product refined from mineral oil through hydrocracking technology. It is a mixture of mineral oil and fully synthetic oil in a 4:6 ratio. Semi-synthetic oil's purity is very close to that of fully synthetic oil, but its cost is slightly higher than mineral oil, making it an ideal transitional product from mineral oil to synthetic oil. Fully synthetic oil: The highest grade of engine oil, derived from ethylene and propylene dispersed from natural gas or crude oil, undergoes complex chemical reactions such as polymerization and catalysis to form a lubricating fluid composed of large molecules. Notes on selecting engine oil: The viscosity of engine oil changes with temperature, so special attention should be paid to its performance under low and high temperatures. For example, in 5W-30, the number before the W indicates low-temperature fluidity, with 5W representing the ability to withstand -30°C. The smaller this number, the better the low-temperature fluidity, ensuring smoother cold starts for the car. The number after the W represents the oil's kinematic viscosity at 100°C, with higher numbers indicating better ability to maintain viscosity at high temperatures, which can also be understood as better lubrication performance under high temperatures. Engine oil should be selected based on the engine's requirements. It is unnecessary to use overly advanced oil in engines with lower requirements, nor should lower-grade oil be used in engines with higher requirements. Multi-grade oils are preferred due to their cost-effectiveness, long lifespan, and high efficiency, providing better protection for the engine. Based on the characteristics of multi-grade oils, they may appear darker prematurely and have lower oil pressure compared to conventional oils, both of which are normal phenomena.

What is the fuel consumption per 100 kilometers for the Volkswagen T-Roc 1.4T?

The fuel consumption per 100 kilometers for the Volkswagen T-Roc 1.4T is 5.9-7.0L. Currently, there are 5 models available for sale. Among them, the T-Roc 2021 two-wheel-drive Elite Smart Connect Edition has a fuel consumption of 7L per 100 kilometers, while the two-wheel-drive Comfort Smart Connect Edition, two-wheel-drive R-Line-Pro Smart Connect Edition, two-wheel-drive Luxury Smart Connect Edition, and four-wheel-drive Luxury Smart Connect Edition have a fuel consumption of 5.9L per 100 kilometers. The above figures are the NEDC combined fuel consumption, which is the data measured under the NEDC test procedure for comprehensive operating conditions. The actual fuel consumption is higher than this value, ranging from 7.35-7.89L/100km. Among comparable models, the Tharu 2021 has a combined fuel consumption of 5.9L/100km, the Qashqai 2022 has a combined fuel consumption of 6.2L/100km, and the Tang 2021 has a combined fuel consumption of 9L/100km. The fuel consumption of a car is directly related to five major factors: driving habits, the car itself, road conditions, natural wind direction, and environmental temperature. Specific factors that can increase a car's fuel consumption are as follows: Driving habits: Aggressive driving, such as sudden acceleration, overtaking, or not easing off the throttle in advance when approaching a red light, can increase fuel consumption. The car itself: Cars with larger displacements generally consume more fuel than those with smaller displacements because larger displacements usually mean greater power, requiring more gasoline to burn and perform work. Cars with greater weight also have higher fuel consumption because greater weight requires more driving torque. Road conditions: Driving on dirt roads, muddy roads, soft surfaces, or mountainous roads increases resistance and fuel consumption. Natural wind direction: Driving against the wind or on windy days increases the car's resistance and fuel consumption. Low environmental temperature: When the engine block humidity is low, the gasoline injected during a cold start is less likely to atomize, requiring more gasoline to be injected for combustion, thus increasing fuel consumption. Additionally, at low temperatures, the engine's computer controls the engine to run at higher RPMs to warm up the car, which also increases fuel consumption.
