Is Slight Shaking Normal After an Oil Change?

If the engine did not exhibit slight shaking before the oil change but starts to shake slightly after the oil change, this situation is abnormal. Reasons for car shaking after an oil change: 1. Oil Fill Level: If too much oil is added, the excess oil can easily enter the combustion chamber and form gummy carbon deposits. While there may be no obvious effects initially, over time, the carbon deposits will become increasingly severe, leading not only to idle shaking but also potentially clogging the catalytic converter, causing excessive exhaust emissions. In severe cases, it may even result in oil burning. 2. Oil Viscosity and Quality: It is crucial to choose oil that matches the vehicle model. If oil with excessively high viscosity is selected, it will inevitably affect the oil's flowability, which can cause engine shaking during idle. Additionally, the quality of the oil must be carefully considered. Low-quality oils often lack reliable quality assurance, which can not only lead to idle shaking but also directly impact the vehicle's overall performance.

How many days does it take for a new car to be delivered to the 4S store?

Generally, the transportation time is about half a month, and for rare models, the time to be transported to the 4S store is relatively longer. The time to pick up the car at the 4S store is as follows: 1. If there is no stock car, the 4S store needs to order the car from the manufacturer. This time is uncertain, usually taking two weeks to a month, and it also depends on the production volume of the car manufacturer. 2. If there is a stock car, the car is at the 4S store. Even if the car is at the 4S store, there are two situations: (1) If the vehicle certificate is at the store, the car can be picked up on the same day. (2) If the vehicle certificate is not at the store, after paying the deposit on the same day, it will take three days to pick up the car. This is because the 4S store needs to redeem the certificate from the bank, and the courier takes about two to three days to deliver it to the store.

What Causes the Brake Pedal to Be Hard to Press When Starting the Engine?

Introduction to the reasons why the brake pedal is hard to press when starting the engine: Pressing the brake before shutting off the engine: This is related to pressing the brake before shutting off the engine. The car's braking system operates at its maximum efficiency when the engine is running, and the brake booster is the key component that amplifies the force applied to the pedal. In such cases, simply restart the engine and try pressing the brake pedal firmly again. Once the engine is running, the brake booster will resume functioning, and the brake pedal will return to normal. Brake booster air leakage or malfunction: If you did not press the brake pedal after the car was turned off, or if you notice the brake pedal is hard to press while driving, it is likely due to a malfunction in the brake booster. This could be caused by a vacuum tube leak or blockage in the brake booster. It is advisable to take the car to a repair shop for inspection. If this issue occurs while driving, do not panic. The first priority is to slow down and stop the vehicle. You can try pressing the pedal multiple times to see if braking can be restored. Applying more force usually allows some braking power to be applied.

What Are the Causes of Brake System Failure?

Introduction to the causes of brake system failure: Severe wear of brake pads: Brake pads are divided into two types: those with sensor lines and those without. For those with sensor lines, when the brake pads wear to the limit position, the sensor line will automatically connect the circuit, triggering the fault light. Low brake fluid level: Brake fluid plays a crucial role in the vehicle's braking system. When the driver presses the brake pedal, the force applied is transmitted by the piston in the master cylinder through the brake fluid to the wheel cylinders located at each wheel, causing the brake pads to contact the wheels and stop the vehicle. A lack of brake fluid is often accompanied by significantly reduced braking force, and in severe cases, a complete loss of braking power. This issue can be resolved by promptly replenishing the brake fluid. Brake system oil leakage or false alarm: If the brake system warning light comes on while driving, the driver should remain calm, slow down as much as possible, pull over promptly, and then proceed to diagnose the cause of the fault.

Has the Envision Been Discontinued?

The Buick Envision has indeed been discontinued, and there are currently very few vehicles available for sale. While the Envision achieved remarkable success in the past, product updates are essential. Its design now appears somewhat outdated and lacks appeal to younger consumers. With the introduction of the Envision S and Envision Plus, the older Envision model has inevitably exited the market. 1. Model Details: On December 18, 2018, SAIC announced through the Buick brand the launch of the 2019 Buick Envision National VI version, offering 1.5T and 2.0T engine options, each available in both front-wheel drive and all-wheel drive configurations. The 1.5T engine is paired with a 7-speed dual-clutch transmission, while the 2.0T engine comes with a 9-speed HYDRA-MATIC intelligent transmission. 2. Successor Model: As the successor to the Envision, the Envision Plus shares a very similar design language, demonstrating strong continuity. In terms of dimensions, the Envision Plus is notably larger, with a standard SUV body style. Its dimensions are 4845/1883/1695mm, with a wheelbase of 2833mm, classifying it as a midsize SUV.

What Does Vehicle Emission Exceeding Limits Mean?

Emission exceeding limits refers to a vehicle's emissions surpassing the prescribed emission standards. Currently, most regions in China implement the National V standard, while some have already adopted the National VI standard. Consequences of Excessive Vehicle Emissions: Generally, vehicles with excessive emissions are subject to fines. For example, if a motor vehicle emits pollutants exceeding the specified standards and refuses to rectify the issue within the ordered deadline, it will be fined and receive three penalty points. If a vehicle fails a random tailpipe emission inspection, the traffic police department will temporarily confiscate the vehicle's license on the spot. The owner must carry out repairs and rectifications within 7 days and can only retrieve the license upon presenting a passing re-inspection certificate. Failing the tailpipe emission test during the annual vehicle inspection is the main reason owners face penalties during the process. Reasons for Failing Tailpipe Emission Tests During Annual Vehicle Inspections: In major cities across China, many private vehicles fail tailpipe emission tests during annual inspections. There are various reasons for this failure. On one hand, the country is becoming increasingly stringent in tailpipe emission regulations. On the other hand, private vehicle owners often lack professional maintenance skills and knowledge, making it difficult to effectively address excessive emissions, which is also a significant contributing factor.
