Currently, the main grade is SN. The API on engine oil stands for the American Petroleum Institute, and it is divided into grades SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM, and SN. Below are the specific details: Engine Oil: The primary functions are lubrication, cleaning, and rust prevention. The ultimate goal is to extend the engine's lifespan. Generally, higher-grade engine oils provide better protection for the engine, so the price of the oil is proportional to its effectiveness. Full Synthetic Oil: It can operate over a wider temperature range and has a longer service life. Under the same oil film requirements, synthetic oil can achieve the desired performance with a lower viscosity.

What causes the Kia K3 trunk to not open and make abnormal noises?

The reasons why the Kia K3 trunk cannot open and makes abnormal noises include the car not being unlocked, the trunk latch being stuck, and the trunk latch being deformed. Detailed explanations of the causes and corresponding solutions are as follows: Vehicle not unlocked: If the vehicle is in an unlocked state, both the doors and the trunk will be locked, making it impossible to open. In this case, simply unlocking the car will allow the trunk to open normally. Trunk latch stuck: If the trunk latch is stuck, the trunk will be difficult to open due to friction. In this situation, applying lubricant to the latch position to ensure smooth operation will resolve the issue. Trunk latch deformed: If the vehicle has been involved in a collision causing the trunk latch to deform, the trunk may also fail to open. In this scenario, the trunk will need to be repaired or replaced. The Kia K3 is equipped with a 1.4T turbocharged engine and a 1.6L naturally aspirated engine, delivering maximum horsepower of 130/128 PS, maximum power of 96/94 kW, and maximum torque of 211/156 Nm.

What happens if you press the clutch and accelerator together?

Pressing the clutch and accelerator together prevents the car from moving forward. To shift gears, you should first press the brake to slow down, then press the clutch to shift. When stopping, you can directly press the clutch and brake. The clutch is part of the car's transmission system, connecting or disconnecting the engine from the gearbox. The functions of the clutch are: 1. Ensuring smooth car starts; 2. Enabling smooth gear shifts. Proper coordination between the clutch and accelerator: 1. Starting: Press the clutch with your left foot and the brake with your right foot, shift into first gear, release the handbrake, slowly lift the clutch with your left foot, and when the car starts to vibrate slightly, move your right foot to the accelerator pedal and gently press it while continuing to release the clutch for a smooth start. Once the car starts moving smoothly, fully release the clutch with your left foot and press the accelerator to prepare for shifting. 2. Upshifting: Release the accelerator pedal, quickly press the clutch pedal with your left foot, shift the gear lever to the appropriate gear, release the clutch pedal while slowly pressing the accelerator with your right foot. 3. Downshifting: First press the brake to slow down, lightly tap the accelerator with your right foot, quickly press the clutch pedal with your left foot, shift the gear lever to the appropriate gear, release the clutch pedal while slowly pressing the accelerator with your right foot.

What are the reasons for the Wuling Hongguang's lack of acceleration?

The reasons for the Wuling Hongguang's lack of acceleration include vehicle idle vibration, poor fuel quality, spark plug misfire, insufficient engine oil, and other issues. Vehicle idle vibration: A dirty throttle or a faulty throttle can cause idle vibration. The main reason for a dirty throttle is the accumulation of carbon deposits at the junction of the throttle valve plate shaft and the throttle body, leading to imprecise throttle opening and resulting in idle vibration. Poor fuel quality: Poor fuel quality can cause poor atomization at the fuel injector, leading to incomplete combustion of the air-fuel mixture in the cylinder, which also results in idle vibration. It is recommended to use higher-grade gasoline after finishing the current tank and perform a fuel system cleaning. Spark plug misfire: If the spark plug fails to ignite, causing one or more cylinders to stop working, this will also lead to idle vibration. Check the spark plugs; if there are cracks in the ceramic part, also inspect whether the ignition module is functioning properly. Insufficient engine oil: Prolonged insufficient engine oil can lead to reduced power and increased fuel consumption in mild cases, and in severe cases, piston impact on the valves, causing mechanical damage to related components. Additionally, a faulty fuel pump or a clogged fuel filter can also reduce engine power.
