0W engine oil has higher quality requirements. Here is the relevant introduction to the selection method of engine oil: 1. Principle: The selection of engine oil is very particular. Car owners can choose engine oil based on the local highest and lowest temperatures, the grade of the vehicle, and the condition of the vehicle; 2. Differences between different engine oils: If engine oil with too high viscosity is selected, it will increase movement resistance and affect engine power; If engine oil with too low viscosity is selected, it cannot guarantee lubrication quality and will aggravate engine wear; 3. How to choose: For engines that are already severely worn and have larger clearances, a higher viscosity grade of engine oil can be selected to enhance the sealing performance of the components. Simply put, new cars are better suited for thinner engine oil, while cars with higher mileage are better suited for thicker engine oil.

Why is the 'Study to Reduce Points' program not available in Changzhou?

Changzhou's 'Study to Reduce Points' program is still available. You need to register, complete real-name authentication, and bind a vehicle under your name. After successful authentication, you can enter the 'Study to Reduce Points' module to participate in learning and exams. Purpose of the 'Study to Reduce Points' program: The 'Study to Reduce Points' program is designed to reduce existing demerit points on your driver's license, not to add points or replace penalty points for traffic violations. The points obtained through this program are used to clear demerit records. For example, if you were penalized with 6 points for a violation, passing the 'Study to Reduce Points' exam would clear these 6 points, allowing you to start fresh. Regulations for the 'Study to Reduce Points' program: The number of points you can still deduct after participating in the program depends on how many points you had before the study, but the total accumulated points cannot exceed 11. Regardless of participation in the program, a driver's license only has 12 points. The 'Study to Reduce Points' program can only reduce existing demerit points on the license, not increase the total points to 18.

How many kilometers for the first maintenance of the Jog i?

The first maintenance for the Jog i is at 300 kilometers. The relevant introduction of the first maintenance is as follows: The timing of the first maintenance varies by vehicle: It is usually performed after driving 1000-3000 kilometers. The car must attend the first maintenance on time, neither earlier nor later. Completing the first maintenance indicates that the vehicle's break-in period has ended, and it can be driven according to the vehicle's specified standards and normal speed. The first maintenance time starts from the date of vehicle pickup. First maintenance items: The most important aspect of the first maintenance for a new car is not just changing the oil, but also conducting a comprehensive inspection and diagnosis of the car's condition and usage. There are many items to check during the full vehicle inspection, mainly including whether the headlights are working, whether the high beams are functioning normally, their brightness and height, and whether the turn signals are all working; whether the wipers clean effectively; the sealing of the rubber strips; whether there is any noise from the sunroof; whether the hinges of the doors are sufficiently lubricated; the tire pressure, whether the pressure in all four tires is normal, etc. All these need to be checked.

Where is the fuel gauge on the Harley X48?

Harley X48 fuel gauge is located on the dashboard. Function of fuel gauge: The fuel gauge on the Harley X48 is used to indicate the amount of fuel remaining in the tank. It consists of a fuel level indicator with a voltage regulator and a fuel level sensor. The low fuel warning device is designed to illuminate immediately when the fuel level in the tank falls below a certain threshold, alerting the rider to the low fuel condition. Types of fuel gauges: There are two types of fuel gauges: analog and digital. The analog fuel gauge uses a pointer to indicate the fuel level, with the letters E and F marked on the gauge. F stands for full, and E stands for empty. When the fuel icon lights up, it indicates that the remaining fuel is low and needs to be refueled as soon as possible. The digital fuel gauge displays the remaining fuel through illuminated segments. The more segments that are lit, the more fuel remains. When only 1-2 segments are lit, it indicates low fuel and requires timely refueling.

What are the symptoms of a faulty camshaft adjuster?

The symptoms of a faulty camshaft adjuster are as follows: 1. The generator does not generate electricity, and the battery indicator light on the dashboard illuminates. This is usually caused by the breakdown of the internal field-effect transistor or Darlington transistor in the voltage regulator. 2. Excessive power generation can lead to easy battery damage. If the battery voltage drops below 10V, it will be difficult to start the car, affecting the battery's lifespan. 3. Damage to the generator regulator can result in no power generation, affecting vehicle performance, causing weak acceleration, and increased fuel consumption. A faulty camshaft adjuster may cause the following issues: 1. The car has a high-voltage spark, but it takes a long time to start, though the car can eventually run. 2. During the starting process, the crankshaft may reverse, and backfire may occur in the intake manifold. 3. Unstable idling with severe shaking, similar to a car misfiring. 4. Weak acceleration, making the car difficult to run, though it may improve slightly if the RPM exceeds 2500 per minute. 5. Increased fuel consumption, excessive exhaust emissions, and the emission of foul-smelling black smoke from the exhaust pipe.

Can ETC locate a vehicle?

ETC cannot locate a vehicle. ETC is an electronic toll collection system that allows vehicles to pass through without stopping. ETC dedicated lanes are designed for vehicles equipped with ETC onboard units, utilizing electronic toll collection methods. It is a radio frequency system without any positioning capabilities. More details are as follows: 1. The ETC system is currently the most advanced toll collection method for roads and bridges worldwide. It uses dedicated short-range microwave communication between the onboard electronic tag installed on the vehicle's windshield and the microwave antenna in the ETC lane at the toll station. This system integrates with computer networking technology to process backend settlements with banks, enabling vehicles to pass through toll stations without stopping while paying the toll. 2. Implementing non-stop toll collection allows vehicles to pass through at high speeds (tens to over a hundred kilometers per hour), significantly improving road traffic capacity. The shift to electronic tolling reduces the cost of toll management and enhances vehicle operational efficiency. It also greatly reduces noise and exhaust emissions at toll booths. With the substantial increase in traffic capacity, the scale of toll stations can be reduced, saving on infrastructure and management costs. 3. Additionally, for cities, the ETC system is not just an advanced tolling technology but also an effective traffic management tool that uses economic leverage to regulate traffic flow. For busy bridges and tunnels, the ETC system overcomes the limitations of monthly passes and manual toll collection, effectively improving the financial recovery capability of these municipal facilities.
