New cars should have their engine oil changed at around 2,500 kilometers to better remove metal debris generated during the engine break-in period. For vehicles driven less frequently, the oil can be changed once a year. For vehicles frequently driven or often used in low-temperature conditions, it is recommended to change the engine oil and oil filter every 5,000-7,000 kilometers for optimal performance. Below are specific details about engine oil: 1. Classification of engine oil: Engine oil can be categorized into mineral oil, semi-synthetic oil, and full synthetic oil. 2. Replacement intervals: If using mineral oil, it should generally be changed every six months or around 5,000 kilometers. If using semi-synthetic oil, change it every 7-8 months or around 7,500 kilometers. If using full synthetic oil, it can be changed after about one year or 10,000 kilometers.

Should You Press the Clutch and Brake When Starting the Car?

When starting the car, it is necessary to press the clutch and brake to ensure a smooth ignition. Below are the specific introductions to the brake and clutch: 1. Brake: The car's brake pedal is located under the steering wheel. Pressing the brake pedal causes the brake lever to be pressurized and transmitted to the brake pads on the brake drum, which then clamp the brake disc, slowing down or stopping the car. 2. Clutch: The clutch is located in the flywheel housing between the engine and the transmission. The clutch assembly is fixed to the rear plane of the flywheel with screws, and the output shaft of the clutch is the input shaft of the transmission. While driving, the driver can press or release the clutch pedal as needed to temporarily separate or gradually engage the engine and the transmission, thereby cutting off or transmitting the power from the engine to the transmission.

What is the transmission oil model for the new Alto?

The new Alto has different models. For automatic transmissions, use automatic transmission fluid (ATF), and for manual transmissions, use gear oil. Hazards of not changing transmission oil: 1. Damage to the transmission's shift control mechanism; 2. Abnormal wear of gears and clutch plates inside the transmission; 3. Affects the normal operation of the transmission, leading to damage to the transmission valve body. Transmission oil is different from engine oil. Although both oils serve a lubricating function, their specific roles differ and should not be confused. Differences: Engine oil is a lubricant for the engine system, possessing properties such as oxidation resistance, anti-wear, and anti-corrosion. Transmission oil, on the other hand, is primarily used to keep the shift system clean and extend the service life of internal transmission components. Due to the different structures and operating environments of the transmission and engine, transmission oil cannot be used as engine oil, nor can engine oil be used as transmission oil.

What Causes the Noise from the Rear Axle of a Honda CR-V 4WD When Turning?

The noise during turning is caused by the steering resistance pump reaching its limit. Here are the specific details: 1. Tire Usage: If abnormal noises come from the chassis while driving, it is necessary to have it inspected and corrected at a 4S shop. When car tires come into contact with the ground, they produce various levels of noise due to the type or unevenness of the road, the vehicle's speed, the type of tires, and the tire's own air pressure. No matter how perfect the car is, it cannot completely eliminate the noise generated between the tires and the ground during driving. It is necessary to check whether the tire screws are tightened to eliminate the noise symptoms. 2. Vibration Situation: Check whether components such as the tie rod ball joint, swing arm bushings, or planar pressure bearings are loose. In addition, issues like front wheel toe-in, wheel hub bearings, and shock absorbers can also cause noise and vibration. Specifically, the front suspension and related parts need to be inspected.
