How often should gearbox oil be changed?

Generally, it should be replaced every 3 to 4 years, or when the mileage reaches 60,000 to 80,000 kilometers. Gear oil and transmission oil: There is no difference between gear oil and transmission oil. Transmission oil and gear oil are usually the same, with corresponding models used according to different vehicle types. Manual transmission vehicles mainly use it for gear lubrication, while automatic transmission vehicles primarily use it for transmission lubrication and power transmission. Introduction to gear oil: Gear oil is mainly composed of petroleum lubricating base oil or synthetic lubricating oil, with the addition of extreme pressure anti-wear agents and oiliness agents. It is an important lubricating oil used in various gear transmission devices to prevent tooth surface wear, scuffing, sintering, etc., thereby extending their service life and improving power transmission efficiency.

What does the yellow exclamation mark on the odometer mean?

There are four possible scenarios when a yellow exclamation mark appears on the car dashboard: general fault, automatic transmission fault, abnormal tire pressure, and lighting fault. Below is a detailed analysis of these four situations: General Fault: A triangle with an exclamation mark inside indicates a malfunction in the vehicle's general performance, components, or functions. Common issues include parking sensor failure, fuel cutoff system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. It is necessary to visit a 4S shop for inspection to identify the source of the fault. Automatic Transmission Fault: A yellow gear with an exclamation mark inside is the automatic transmission fault warning light, indicating a problem with the transmission or that the transmission fluid is below the normal range. The transmission fluid should be replaced promptly. Abnormal Tire Pressure: An exclamation mark inside a horizontal line below a bracket represents the tire pressure monitoring warning light. This light illuminates when the tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting Fault: A yellow bulb with an exclamation mark is the lighting fault indicator, signaling that a car light has malfunctioned. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check, focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue. Additionally, a red exclamation mark inside a circle with parentheses indicates a warning for the braking system, primarily signaling a brake system malfunction or low brake fluid level. The braking system should be inspected immediately to avoid accidents.

What to Do When an Electric Vehicle is Stuck in Traffic on the Highway?

When a pure electric vehicle is stuck in traffic on the highway, it is advisable to avoid frequent starts and stops, as well as prolonged use of the air conditioning. Avoid Frequent Starts and Stops: For fuel-powered vehicles, fuel consumption increases significantly during traffic congestion. Similarly, for electric vehicles, frequent acceleration and braking can lead to a noticeable rise in power consumption. Therefore, when stuck in traffic on the highway, drivers should assess the road conditions carefully. The best approach is to accelerate and decelerate gradually, allowing the vehicle to coast as much as possible, and avoiding sudden acceleration. Rapid acceleration for electric vehicles means a higher discharge rate. Avoid Using the Air Conditioning: Pure electric vehicles rely on electricity to power both heating and cooling systems, so using the air conditioning significantly increases power consumption. During traffic congestion, it is recommended to slightly lower the windows or turn off the air conditioning altogether.

What are the consequences of canceling a Subject 4 appointment?

There are no negative consequences for canceling a Subject 4 appointment, as each individual has three opportunities to cancel appointments for each subject. However, if a student cancels after successfully scheduling the appointment and receiving a confirmation message from the DMV, it may affect their scheduling priority, making it more difficult to book future appointments. If the appointment has not yet been confirmed, canceling will have no impact. Subject 4, also known as the theoretical driving test or driver's theory exam, is part of the motor vehicle driver's license assessment. The test covers topics such as safe and civilized driving practices, safe driving knowledge in adverse weather and complex road conditions, emergency handling methods for situations like tire blowouts, and post-accident handling procedures.

Should New Cars Be Waxed or Coated with Crystal?

New cars do not need and are not recommended to be waxed or coated with crystal. For new cars, simply washing them is sufficient, and no protective measures are necessary. Only when the car's paint feels rough to the touch should you consider waxing or applying a regular coating or glaze. Disadvantages of Waxing: Product Damage: There is a wide variety of car waxes on the market today, each with different properties and effects. Choosing the wrong type or using inferior-quality wax can damage the car's paint. Paint Wear: Due to their abrasive properties, improper application or excessive use of wax with abrasive particles can easily wear down the paint. Disadvantages of Crystal Coating: High Cost: Crystal coating is expensive. Complex Application: It requires skilled technicians and a controlled environment for application. Rapid Aging: It can accelerate the loss of gloss and oxidation of the car's paint.
