How to Determine When to Change Engine Oil for Your Car

The following are methods to determine whether your car needs an oil change: 1. Observe with oil test paper; Take a small amount of oil from the dipstick and drip it onto the oil test paper, then let it sit overnight, waiting for the oil to fully diffuse on the paper. The harder the edges between the diffused oil ring, sediment ring, and diffusion ring, the more the oil performance has deteriorated. 2. Judge based on driving experience after an oil change; Engine oil performance has a 'shelf life.' At a certain point, if you feel the car is sluggish when starting or acceleration slows down, it indicates the oil's 'shelf life' has reached its limit, and it's time for an oil change. Additionally, if you notice a significant improvement in power after changing the oil, it means the last oil change interval was too long. Next time, you can consider changing the oil 500 kilometers earlier. After 1-2 adjustments, you can find a more accurate oil change interval. Additional Information: It's best to replace the oil filter along with the oil change. The oil filter's role is to trap impurities in the oil. If not replaced in time, accumulated impurities can cause blockages. In mild cases, it may lead to insufficient oil pressure and poor lubrication of mechanical parts; in severe cases, it can cause excessive engine wear.

What is the maximum speed of 91H tires?

The maximum speed is 210km/h. 91H is the tire load index, where 91 corresponds to a maximum load of 615 kilograms per tire. H represents the speed rating of the tire, indicating that the maximum speed under specified load conditions is 210km/h. Common vehicle models on the market mostly use H and V ratings, while some high-performance vehicles use W and Y. Tire specifications are symbolic data representing the geometric parameters and physical properties of tires. There are three methods to denote tire specifications: A. Metric (m); B. Mixed metric-imperial; C. Imperial. Imperial tire specifications are often represented by a set of numbers, where the first number indicates the tire section width, and the second number indicates the rim diameter, both in inches. 91H tires refer to tires with a maximum load capacity of 615Kg per tire and a maximum speed of 210KM/h under specified load conditions. Here, 91 is called the load index, which can be referenced against a tire load index chart to determine the maximum load of 615Kg. H is called the speed rating, which, as mentioned earlier, can be referenced against a tire speed rating chart to determine the maximum speed of 210KM/h. The most common identifiers on tires are, first, the tire brand, followed by the tire specifications, and then the load index and speed rating. The speed rating is the maximum speed limit determined during the design and production of the tire after considering various factors and tests. Exceeding this speed can lead to multiple safety hazards. Generally, all-terrain tires (AT) have lower speed ratings compared to highway tires to account for performance on unpaved roads. Load index and pressure. These generally indicate the maximum load and corresponding pressure, with the load measured in "kilograms" and the pressure, or tire pressure, measured in "kilopascals." One side of the tire has rubber strips or blocks indicating the wear limit. When the tire wear approaches about 4mm from this limit, it's time to consider replacement. The so-called three "T"s refer to the three commonly seen identifiers on the sidewall of the tire: Treadwear (wear resistance index), Traction (traction performance), and Temperature (temperature index). These three identifiers are additional to the conventional parameters like size, speed rating, and load rating and can be used to select tires based on their three "T" indices, which are lesser-known to consumers. Besides the model, tires also bear the following common data: Tire cord material: Represented by Chinese pinyin, such as M for cotton cord, R for rayon cord, N for nylon cord, G for steel cord, and ZG for steel radial cord tires. Speed rating: Indicates the maximum speed at which the tire can carry a specified load under defined conditions. Letters A to Z represent certified speed ratings from 4.8km/h to 300km/h. Commonly used speed ratings include: Q: 160km/h; H: 210km/h; V: 240km/h; W: 270km/h; Y: 300km/h. Rim specification: Indicates the rim size compatible with the tire for practical use, e.g., standard rim 5.00F.

How much is the fine for non-functioning brake lights? Will points be deducted?

The specific fine amount for non-functioning brake lights is usually determined by traffic police based on the on-site situation, and generally, no points will be deducted. Categories: Automotive brake lights can be classified by position into three types: rear brake lights located at the back of the car; brake indicator lights on the dashboard; and high-mounted brake lights. By material, they are divided into two types: gas automotive brake lights and LED automotive brake lights. Functions of automotive brake lights: The purpose of rear brake lights and high-mounted brake lights is to make it easier for vehicles behind to notice when the car in front is braking, thereby helping to prevent rear-end collisions. The dashboard brake indicator light serves to alert the driver when the rear brake lights are activated.

Which Subject is Reverse Parking in the Driving Test?

Reverse parking is part of Subject 2 in the driving test. It has been a mandatory requirement for obtaining a small car driver's license since 2013. This test evaluates the driver's ability to maneuver the vehicle in a confined space. Reverse parking is a key assessment point in the driver's test, specifically testing the ability to correctly reverse the vehicle into a parking space from both sides while in motion. Below are three common methods for reverse parking: 1. "Non-Shaped" Reverse Parking: In this method, the vehicle is positioned perpendicular to the target parking space. Using the B-pillar of your car as a reference, you can align with the first parking space and typically reverse into the third space. Key Points: This method is particularly suitable for beginner drivers. The advantage is that, if executed well, it allows for a smooth entry in one attempt. The downside is that it's somewhat rigid; if there are many vehicles on either side or the space is narrow, multiple adjustments may be needed. Most driving students find this method common and relatively easy to learn. 2. "Linear" Parallel Parking: This method uses the car in front as a reference. Align your car with the front car, turn the steering wheel to the right, and after reaching a 45-degree angle between the two cars, observe and straighten the wheel while reversing. If estimated correctly, this can result in a successful entry in one go. However, this method often requires blocking the lane, which can make many students nervous if another car honks, disrupting their rhythm and leading to failure. 3. Diagonal Parking: This type of reverse parking, along with linear parallel parking, usually requires one to two training sessions for students to master. There are also other variations like irregular or slanted parking, which won't be detailed here. During driving lessons, the instructor will cover each method with the students.

What does bobber motorcycle mean?

bobber motorcycle refers to an American-style customized motorcycle. Overview of bobber motorcycles: It involves simplifying and modifying the original factory bike by removing fenders and all unnecessary components to achieve the goals of reducing weight, improving performance, and facilitating maintenance. The American BOBBER style has numerous followers worldwide. Classification of bobber motorcycles: The BOBBER style is mainly divided into American, Japanese, and European styles. It originated in the post-World War II period in the United States. At that time, the American military motorcycles were Harleys, and soldiers who didn't want to pay expensive modification costs did the modifications themselves, removing all unnecessary parts to form this distinctive style.
