Is it necessary to change the rear differential oil?

Rear differential oil needs to be replaced, with a typical replacement interval of 80,000-100,000 kilometers. Changing the differential oil prevents excessive wear of the vehicle's differential gears, which could lead to differential damage. Differential oil serves as the lubricant for the rear axle gear transmission mechanism, also known as gear oil. Its main functions are lubrication and cooling. Due to differences in the axial positions and tooth profiles of gears, there are significant variations in contact stress and relative sliding speed at the meshing surfaces. Therefore, different types of gear oil are required. Failure to replace differential oil increases friction between gears in the differential structure, raises vehicle fuel consumption, and over time can damage components like the differential and differential lock. The functions of differential oil include forming an oil film on gear meshing surfaces to provide lubrication, reducing friction resistance and extending component lifespan; and dissipating heat generated by friction pairs through fluid circulation for cooling purposes. Its working principle involves maintaining differential operation during high-speed driving when lubricant temperatures in the differential become extremely high, far exceeding engine oil temperatures, ensuring normal vehicle operation.

What to Do When the Car Door Makes Noise When Opening?

Door noise is mainly caused by lack of lubrication, but it is necessary to determine whether it is from the door hinge position or internal components such as the window regulator, door lock mechanism, or handle mechanism. You can go to a repair shop and ask the mechanic to clean it, then apply a little oil, and also clean the door stopper and apply some oil, which should improve the situation. Here are some related details: 1. The door and the car body are connected by hinges, similar to a house door, and it is normal for hinges to make noise after prolonged use. To ensure the pulley remains smooth and quiet for a long time, lubricating oil can be applied regularly every 2-3 months for maintenance. 2. If the car has been used for a while, check whether the door seal is aging, as the seal is made of rubber. Over time, the seal will gradually age and deteriorate, which can cause noticeable wind noise and friction sounds for the driver and passengers. If the seal is aged or damaged, it is recommended to replace it directly. Regularly clean the dust and rainwater between the seal gaps during daily use to prevent aging.

What to Pay Attention to When Entering or Exiting Highway Ramps

When entering or exiting highway ramps, it is important to turn on the turn signal in advance, observe oncoming traffic when entering the ramp, control your speed, and most importantly, avoid overtaking. Below are specific precautions: When driving on highways or entering/exiting ramps, make sure to turn on the turn signal ahead of time. When entering the highway from a ramp, you should activate the left turn signal in advance to alert vehicles behind you to yield. Be sure to check for oncoming traffic on the main road before merging into or exiting the highway ramp, and only proceed when it is safe to do so. When driving on a ramp, maintain a controlled speed and avoid speeding, as ramps are often narrow and curved, making it easy to be caught by speed cameras. Always drive at a reduced speed. Do not overtake on ramps. Some ramps have a single lane, while others have multiple lanes with dashed lines for a certain distance. However, even if the lines are dashed, avoid overtaking on ramps because they are typically curved, sometimes sharply. High-speed overtaking can generate strong centrifugal force, increasing the risk of rollovers or side-swipe accidents.

How to Use the Clutch When Driving Uphill?

Correct operation instructions for starting uphill with the clutch: 1. First, when driving halfway up the slope, slowly press both the brake and clutch simultaneously to stop the car on the slope; 2. Then engage the handbrake and shift to neutral, at this time release the brake and clutch, and the vehicle will come to a complete stop; 3. When starting uphill, first press the brake and clutch; 4. Then shift into first gear, while placing your right hand on the handbrake and left hand on the steering wheel; 5. Slowly release the clutch, and you can also slowly release the brake at the same time, observing the changes in the vehicle's condition; 6. When the clutch is released to the point where the vehicle starts to shake, keep your foot on the clutch still and simultaneously release the handbrake with your right hand; 7. If there is no obvious rollback of the vehicle at this time, move your foot from the brake to the accelerator, gently press the accelerator, and slowly release the clutch to start the vehicle.

Where is the fuel tank cap switch of Binrui?

When the Binrui car is in the unlocked state, press the fuel tank door opening actuator switch on the center console to open the fuel tank. The fuel tank cap refers to the box on the car used to store gasoline. It is square in shape, made of stainless steel, and has excellent sealing. There is only a small round entrance, which is as big as the cap of a bottle, making it easy to store. Other precautions for adding engine oil: 1. The higher the viscosity of the engine oil, the better the protection for the engine: High-viscosity engine oil not only adversely affects the fuel consumption of the entire vehicle but also does not protect the engine well. Another function of engine oil is cooling and heat dissipation. When high-viscosity engine oil is blindly used, the performance of engine oil heat dissipation will inevitably weaken. 2. Engine oils cannot be mixed: The additive components in engine oils from different manufacturers are completely different. The chemical components of various additives may vary greatly, not only between different brands but even within the same brand's different product lines. When engine oils from two brands are mixed, chemical reactions may occur under the high temperature of the engine, such as the formation of flocculent substances in the engine oil and an increase in viscosity.

What is the normal tire pressure for a sedan in summer?

In summer, the normal tire pressure range is between 2.3-2.5. If the car is fully loaded with 5 passengers, adjusting the tire pressure to around 2.5 is more suitable; for general two-person occupancy, a tire pressure of 2.3 is also normal. Below is relevant information about tire pressure: 1. Tire pressure, strictly speaking, refers to the air pressure inside the tire. There is a label with standard tire pressure indicators on the rear of the driver's side door, which indicates the pressure when the tires are cold, i.e., after the car has been parked for at least three hours or driven no more than 1.6 km. Measuring tire pressure when the tires are cold yields the most accurate results. 2. Air pressure is crucial for tires; both too high and too low pressure will shorten the tire's lifespan. Insufficient pressure increases tire deformation, leading to cracks on the tire sidewalls and excessive flexing, which causes overheating, accelerates rubber aging, fatigues the cord layers, and may break the cords. It also increases the tire's contact area with the ground, accelerating shoulder wear. Excessive pressure overstretches the tire cords, reducing the tire's elasticity and increasing the load on the car during driving. In case of impact, it may cause internal cracks or blowouts. Additionally, high pressure accelerates tread wear and reduces puncture resistance.
