Car odometers are not the same as the actual mileage. Reasons for inaccuracy: 1. Internal sensor failure: The odometer inaccuracy is likely due to a sensor issue, such as internal sensor failure or the sensor being too far from the transmission's induction coil (gear ring). It could also be that the vehicle's computer needs adjustment, which varies by car model. It is recommended to contact a 4S shop for inspection. 2. Flange lock nut loosening: When the speedometer and odometer readings are inaccurate, with significant mileage discrepancies, it may be due to a loosened flange lock nut, causing the previously tightened odometer flexible shaft drive gear to slip. 3. Mechanical wear: Excessive wear of instrument components or degraded magnet magnetism can also lead to inaccurate data readings.

What Are the Symptoms of Carbon Buildup in Cars?

Severe carbon buildup in a car can alter the original structural parameters of the engine, reduce engine power, and increase fuel consumption. In severe cases, it can also cause engine knocking, abnormal acceleration noises, and damage to the pistons and crankshaft. Here are some precautions to reduce carbon buildup: 1. Use high-quality fuel: Since the main components of carbon deposits are wax and gum deposits in the fuel, the lower the gum content in the fuel, the better. 2. Avoid driving at low speeds for extended periods: You can periodically drive at high speeds. The principle behind using high-speed driving to remove carbon deposits is to accelerate gas flow, which helps remove a small portion of loosely attached carbon deposits. It also raises the combustion temperature, allowing some carbon deposits in the cylinders to be burned off.

How to Inspect the Paint Surface of a Used Car?

Check for color differences, dirt spots, cracking, and peeling. Below are detailed explanations regarding the paint surface of a used car: 1. Composition of the Paint Surface: Generally, a car's paint surface consists of four fundamental layers: the electrocoat layer, primer layer, basecoat layer, and clearcoat layer. The electrocoat layer primarily prevents rust and enhances adhesion between layers, serving as the foundation for all paint layers. The primer layer acts as a transitional coating, protecting the electrocoat layer while providing adhesion for the basecoat layer. The basecoat layer offers the most direct color perception, and the quality of its application directly affects the vibrancy of the car's color. The clearcoat layer is a transparent coating that enhances gloss and protects against minor scratches. 2. Methods for Inspecting the Paint: Examine the paint by observing light reflection. When the paint surface is smooth, inspect it against the light to determine if it has been repainted based on the brightness of the reflections. Generally, if the reflections vary in brightness, the darker areas indicate repainted sections. Look for sanding marks on the paint. When a vehicle suffers extensive collision damage, large areas of paint may require repair. During the repair process, technicians may not achieve a perfectly smooth surface when sanding the filler, resulting in wavy streaks of varying thickness in the repainted areas.
