What is the shelf life of engine oil?

The shelf life of opened engine oil is about one year, while unopened engine oil can last up to 5 years. Once poured into the engine, the oil has a shelf life of 6 months. Below are details regarding the shelf life of engine oil: 1. Unopened engine oil typically has a shelf life of around 5 years, though some oils may have a 10-year shelf life. 2. Engine oil poured into the engine: For oil that has been poured into the engine but used only occasionally—such as in vehicles that will be left unused for extended periods—if the oil was recently changed before long-term storage, it is recommended to replace it with fresh oil if more than 6 months have passed. If the oil has already been used for a considerable period, the storage time should be shorter; it is advisable to replace it if left unused for more than 3 months. 3. Leftover oil after maintenance: If stored properly, leftover oil from maintenance can last about a year. However, for safety, it is recommended to use it within six months.

The specific position depends on the vehicle's structure, generally including the following places: 1. Above the driver's right-hand armrest box; 2. To the left of the driver's seat; 3. Inside the car door storage compartment. The car fire extinguisher is specifically designed for vehicle fire suppression and includes two main types: 1. Non-pressure storage hanging type ultra-fine dry powder automatic fire extinguishing device for vehicles; 2. Miniature vehicle pressure storage hanging type ultra-fine dry powder automatic fire extinguishing device. The usage method of the car fire extinguisher is as follows: 1. Bring the extinguisher near the fire scene and stand on the upwind side; 2. Pull out the safety pin, hold the nozzle tightly with one hand, press the handle with the other hand, and sweep the nozzle at the base of the flame.

What does it mean when the engine yellow light on the dashboard is on?

The reasons for the engine yellow light on the dashboard being illuminated are as follows: 1. Sensor issues: Sensors include those for coolant temperature, crankshaft position, air flow, intake air temperature, oxygen, etc. When these sensors are damaged, have poor contact, or experience signal interruption, the vehicle's ECU cannot accurately obtain engine data, which will trigger the engine fault light. 2. Maintenance issues: Poor engine maintenance is the most common cause of the engine fault light coming on. 3. Fuel and oil quality issues: The quality of fuel and engine oil matters. The fuel added to a car usually has a specific grade, and engine oil can be semi-synthetic or fully synthetic. If the owner does not follow the required specifications for these, it can lead to engine wear over time. 4. Poor combustion of the air-fuel mixture: Faulty spark plugs, ignition coils, fuel pumps, or clogged fuel lines can all cause poor combustion of the air-fuel mixture in the engine. This can lead to engine carbon buildup or knocking, which the engine's oxygen sensor will detect and report to the ECU, triggering the fault light as a warning. 5. Air intake issues: The engine requires air intake during combustion, making the air filter crucial. If the car's air filter is dirty and not cleaned regularly, it can affect the engine's air intake, potentially leading to blockages over time. In severe cases, this can cause the engine fault light to illuminate.

What are the precautions after replacing brake pads?

After installing new brake pads, it is necessary to break them in. The relevant precautions are as follows: 1. Find a place with good road conditions and few vehicles to start the break-in process. Accelerate to 60 km/h, gently apply the brakes, and use moderate braking force to reduce the speed to about 10 km/h; 2. Release the brakes and drive a few kilometers to allow the brake pads and discs to cool slightly, then repeat the above steps at least 10 times; 3. The broken-in brake pads still require several hundred kilometers of driving to achieve optimal performance with the brake discs. During this period, drive carefully to prevent accidents.
