Here are the specific reasons for the oil light coming on and the car shaking: 1. Insufficient oil volume: The oil pump's pumping volume decreases or fails to pump oil due to air intake, resulting in a drop in oil pressure. 2. Engine overheating: This thins the oil, causing it to leak excessively through the gaps and leading to a drop in oil pressure. 3. Clogged oil filter: A blocked oil filter or oil suction screen will reduce oil pressure. 4. Incorrect oil selection: Using the wrong type or grade of oil can cause increased leakage due to the oil's low viscosity during engine operation, thereby reducing oil pressure.

How Many Years Are Exempt from Inspection for Small Cars, and Which Year Requires an Inspection?

Small passenger cars are exempt from inspection for the first 2 years and require an inspection in the seventh year. Additionally, they must undergo an annual inspection every 2 years within the first 6 years. Below is relevant information about small car inspections: 1. Rules for small car inspections: According to Article 16 of the "Regulations for the Implementation of the Road Traffic Safety Law," effective from July 1, 2018, motor vehicles must undergo safety technical inspections within the following periods from the date of registration: passenger vehicles for commercial use must be inspected annually within the first 5 years, and every 6 months after exceeding 5 years, etc. 2. Rules for vehicle inspection labels: Starting from June 20, 2020, electronic vehicle inspection labels have been implemented nationwide. Electronic inspection labels are issued through the unified national internet traffic safety service platform. Vehicle owners can apply for electronic inspection labels via the internet traffic safety service platform or the "Traffic Management 12123" mobile app.

What kind of engine oil is recommended for Golf?

Golf is recommended to use fully synthetic engine oil. The following are the differences between fully synthetic and semi-synthetic engine oils: 1. Different usage environments: Fully synthetic engine oil: Fully synthetic engine oil has a wider temperature range and longer service life, achieving engine protection with lower viscosity. Semi-synthetic engine oil: It is not suitable for use in low-temperature regions and has a shorter service life. 2. Different qualities: Fully synthetic engine oil: Fully synthetic engine oil is a high-grade oil among engine oils. It is made from ethylene and propylene dispersed from natural gas or gas in crude oil, which are then polymerized and catalyzed through complex chemical reactions to form a lubricating fluid composed of large molecules. Semi-synthetic engine oil: Semi-synthetic engine oil contains a smaller percentage of high-performance fluids and includes conventional mineral oil, utilizing the poorer components of crude oil.

What Causes the Focus Engine to Shake?

The reasons and solutions for the Focus engine shaking are as follows: 1. Ignition system failure: Spark plugs, high-voltage wires, and ignition coils may experience poor performance after a certain period of use. Solution: Check the condition of the spark plugs, high-voltage wires, and ignition coils, and replace the spark plugs if necessary. 2. Aging engine components: When the car engine is idling and the electrical system is turned on, it increases the engine load, causing idle speed to drop. To compensate for the shaking caused by the drop in idle speed, the engine will automatically increase the RPM slightly. Solution: Replace the engine mounts. 3. Unstable oil pressure: Abnormal fuel pump pressure or incorrect readings and poor performance of the intake pressure sensor can also cause engine shaking. Solution: Visit a 4S shop to check the fuel pressure and the intake pressure sensor for normal operation, and replace related components if necessary.

How to turn off the BMW X3 auto start-stop system?

Method to turn off the BMW X3 auto start-stop function: Simply press the A-off button manually to deactivate it. Below is an introduction to the auto start-stop feature: 1. Working principle: The auto start-stop function automatically shuts off the engine when the car is waiting at a traffic light or briefly stopped, and automatically restarts the engine when needed. Its working principle involves installing a reinforced motor with start-stop functionality on the engine. When the conditions for stopping are met, the engine stops operating, and when it's time to move forward, the motor issues a start command, enabling the engine to start in the shortest possible time. 2. Advantages: The auto start-stop function can save fuel consumption and reduce exhaust emissions into the air. According to statistics, under normal circumstances, a car can save 5% of fuel, and in congested road conditions, it can save up to 15% of fuel, contributing to energy conservation and environmental protection.

How many liters of engine oil does a Subaru Forester need?

Subaru Forester requires approximately 5 liters of engine oil for an oil change. Additional information: 1. Method for checking engine oil: After adding the oil, start the vehicle and then turn it off. Wait for 3 minutes before checking the oil level. This is because the oil filter is also replaced during an oil change, and the new oil filter is initially empty. Starting the vehicle allows oil to flow into the oil filter. Waiting for 3 minutes ensures that the oil has settled into the oil pan, providing a more accurate reading. 2. Effects of too much or too little oil: Excessive oil can interfere with the normal operation of the crankshaft and increase the vehicle's fuel consumption. Specifically, when the crankshaft journal moves to the bottom dead center, it may come into contact with the excess oil, creating resistance and disrupting normal operation, which is not permissible. On the other hand, insufficient oil means there won't be enough for proper circulation and lubrication, leading to accelerated wear of internal engine components and potential engine damage.
