What is the oil specification for Vios?

Vios comes with 0W20 factory-fill oil – Toyota's specialized engine oil. For subsequent maintenance oil changes, you can choose from brands like Mobil, Castrol, Shell, or Dusuo Lubricant. The official Vios manual recommends oil specifications of 0W20, 5W20, or 5W30. Oil viscosity changes with temperature, so special attention should be paid to its performance under both low and high temperatures. For example, in 5W-30: the first number indicates low-temperature fluidity – 5W means it can withstand temperatures as low as -30°C. The smaller this number, the better the low-temperature fluidity, resulting in smoother cold starts for the vehicle. The latter number represents the oil's kinematic viscosity at 100°C – higher values indicate better ability to maintain viscosity under high temperatures, which can also be understood as better lubrication performance under high-temperature conditions. The oil change procedure for Vios is as follows: Wait for the engine temperature to cool down, allowing the oil to flow back to the oil pan; Loosen the drain plug with a wrench and use an oil pan to collect the old oil until the flow stops completely. Start the engine and let it run for 30 seconds to allow oil in the main oil gallery to drain out; Remove the oil filter using a specialized wrench; Apply oil to the gasket of the new oil filter and hand-tighten it clockwise; Add new oil through the engine valve cover filler port – typically about three-quarters of a standard oil bottle; Start the engine and let it run for 5 minutes, then check for leaks around the drain plug and oil filter. Repair if necessary; After stopping the engine, remove the dipstick to verify the oil level is within the standard range.

What Causes Engine Hesitation?

Here are the reasons for engine hesitation: 1. Engine carbon deposits. Carbon buildup, a persistent issue in engines, is a major cause of vehicle hesitation. Whether it's carbon deposits on the fuel injectors, throttle body, intake manifold, or combustion chamber, all can lead to hesitation. 2. Ignition system faults such as spark plug issues, ignition coil failure, leaking cylinder wires, or circuit problems. Problems with spark plugs or ignition coils can cause hesitation, particularly noticeable during acceleration. Faulty spark plugs leading to poor ignition can result in "misfiring," a primary cause of hesitation. 3. Low fuel supply pressure due to faults. Proper fuel pressure ensures fuel atomization. However, clogged fuel lines, fuel pump failures, etc., can reduce pressure, affecting atomization and causing hesitation. Clogs often occur in fuel injectors, fuel filters (if not replaced regularly), or fuel pump screens. 4. Faulty or failing sensors. Sensors act as the ECU's sensory nerves, detecting signals. Malfunctioning sensors prevent the ECU from receiving accurate data to control fuel injection properly, potentially causing hesitation.

Will Gasoline Evaporate If the Fuel Cap Is Not Tightened?

Gasoline is highly volatile. If the fuel cap is not properly closed, gasoline can evaporate through the fuel cap opening, leading to rapid fuel consumption. Additionally, if it rains, water may enter the fuel tank. In hot weather, the evaporation of gasoline can easily ignite or pose a fire hazard. Relevant information about automobile fuel tanks is as follows: 1. Introduction: The automobile fuel tank is the full name of the car's fuel tank. Currently, with the development of the automobile industry and the revitalization of the domestic automobile industry, the demand for automobile fuel tanks from major automobile manufacturers has shown a significant upward trend. 2. Design Principle: Utilizing the heat energy generated by the engine during vehicle operation, a thermal circulation system is added between the engine, fuel tank, and radiator. The original single fuel tank design is transformed into a combined fuel tank consisting of a main tank and an auxiliary tank.

How to Use the Panoramic Camera on the New BMW X3?

The panoramic camera function of the BMW X3 can be operated by downloading the BMW app on your smartphone. Using the app, you can control the vehicle's panoramic cameras to view the surroundings anytime, anywhere. The X3 also features a 3D remote imaging function, which captures the vehicle's surroundings and synthesizes them into a 3D image. This image is then transmitted via the internet to the app, allowing the owner to conveniently check the surroundings of the vehicle. Here is an introduction to the BMW X3: 1. Design: The BMW X3 is an SUV model with a distinctive personality, introducing the new SUV Sports Activity Vehicle concept and equipped with BMW's patented xDrive intelligent all-wheel-drive system. The X3 combines the unique proportions of a Sports Activity Vehicle with classic and innovative design, featuring a fresh and youthful exterior while emphasizing the robust and powerful design characteristics of the BMW brand. The interior of the BMW X3 can accommodate five people, along with plenty of luggage or sports equipment. Currently, the BMW X3 is the latest model in its series. 2. Configuration: The most significant change in the 2020 model is the upgrade of the xDrive25i series to a 12.3-inch full LCD instrument cluster, now standard across the entire lineup. Additionally, the new model adds front seat heating, removes the in-car CD player, and the 9-speaker audio system is no longer optional. The xDrive28i series now includes a hands-free tailgate, front seat heating, Harman/Kardon audio, and a 16-speaker system. The M Sport Design package also includes steering wheel paddle shifters. The xDrive30i adds ACC adaptive cruise control, Harman/Kardon audio, and a 16-speaker system, among other features. In terms of safety, the new model comes standard with road sign recognition, and the xDrive30i adds lane change assist and lane departure warning.

What Causes Engine Oil Emulsification?

Automotive engine oil emulsification occurs due to the presence of water in the engine. This issue is unrelated to the engine itself but is associated with factors such as oil quality, weather conditions, and the operating environment of the engine. Relevant information about engine oil is as follows: 1. Introduction: Engine oil, also known as engine lubricant (English name: Engine-oil), has a density of approximately 0.91×10³ (kg/m³). It serves multiple functions including lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the 'blood' of a vehicle. 2. Composition: Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricants, determining their fundamental properties, while additives compensate for and enhance the performance shortcomings of the base oil, imparting new characteristics. Additives are an essential part of lubricants.

How many points are deducted and what is the fine for crossing solid lines?

Crossing solid lines results in a deduction of 3 points and a fine of 200 yuan. Below is an introduction about vehicle line crossing: 1. Introduction: Violating the prohibition of marking instructions refers to driving against the prohibition markings. Prohibition markings include the yellow solid line on the ground (indicating no crossing of the central divider) and the yellow cross (indicating no parking). Driving over these lines constitutes a violation of the prohibition marking instructions. 2. Categories: Driving behaviors such as changing lanes over solid lines, making U-turns in no-U-turn zones, and making left turns in no-left-turn zones all fall under violations of the prohibition marking instructions. 3. Penalty: According to Article 90 of the 'Road Traffic Safety Law of the People's Republic of China', motor vehicle drivers who violate road traffic safety laws and regulations regarding road traffic rules shall be given a warning or fined not less than 20 yuan but not more than 200 yuan. If there are other provisions in this law, penalties shall be imposed in accordance with those provisions.
