The main maintenance items for a car include checking and replacing the engine oil, oil filter, fuel filter, air filter, cabin air filter, as well as inspecting and maintaining related systems such as spark plugs, transmission, throttle body, etc. The details of these maintenance items are as follows: 1. Engine oil and oil filter: Inspect and maintain the lubrication system to prevent excessive wear of components caused by deteriorated, insufficient, or contaminated oil. The oil filter should be replaced together with the engine oil. 2. Fuel filter: Maintain the fuel supply system to prevent clogged fuel lines due to excessive impurities, which may result in insufficient engine power or stalling. 3. Air filter: Maintain the intake system to prevent dust and impurities from entering the cylinders, which could cause wear in the compression system. The air filter should be cleaned regularly. 4. Cabin air filter: Inspect the cabin air filter to prevent excessive dust accumulation. If dust enters the evaporator, it may lead to insufficient cooling or malfunction of the air conditioning system. If the dust on the filter is not cleaned for a long time, it may produce odors and pollute the air inside the car. 5. Spark plugs: Maintain the ignition system to prevent excessive carbon buildup on the spark plugs, which could cause misfires, electrode leakage, or failure to spark, making the car unable to start. 6. Transmission: Check the transmission gear oil to prevent severe gear wear or breakage, which may cause abnormal noises, gear jumping, or sticking in the transmission. 7. Throttle body: Since the air filter may not completely remove impurities, the throttle body can easily become dirty. If the throttle plate is dirty, it may cause unstable idling, so it needs to be cleaned thoroughly. 8. Other components such as brake fluid, battery, fuel injectors, and brake pads should also be maintained to keep the car in good condition and prevent malfunctions while driving.

What Causes the Mazda6 to Experience Idle Fluctuations and Shaking?

Possible causes of engine idle shaking in the Mazda6 are as follows: 1. Intake manifold or various valve leaks: When air, gasoline vapor, or combustion exhaust that should not enter the intake manifold gets in, it causes the air-fuel mixture to become too rich or too lean, leading to abnormal engine combustion. If the leak affects only individual cylinders, the engine may experience more severe shaking, particularly impacting cold idle conditions. Common causes include: loose intake manifold clamps or cracked rubber hoses; leaking intake manifold gaskets; damaged intake manifolds or other components wearing holes in the manifold; leaking O-ring seals on fuel injectors; disconnected or cracked vacuum hose connectors; excessive opening of the Positive Crankcase Ventilation (PCV) valve; a constantly open charcoal canister valve; or an Exhaust Gas Recirculation (EGR) valve that does not close properly. 2. Fuel injector issues: Uneven fuel injection or poor atomization can lead to power imbalance among cylinders. Common causes include: clogged injectors, poor sealing, or fuel spraying in a stream rather than a mist. 3. Spark plugs and high-tension wires: Faulty spark plugs or high-tension wires can result in reduced spark energy or misfires. Common causes include: incorrect spark plug gap; eroded or damaged spark plug electrodes; carbon buildup on spark plug electrodes; cracked spark plug insulators; excessive resistance in high-tension wires; leaking insulation or connectors on high-tension wires; or eroded or poorly insulated distributor rotor electrodes.

Are Cars Considered Real Estate?

Cars are classified as movable property. Like ships and airplanes, cars are high-speed transportation vehicles, not static property in the personal ownership sense, and they involve public safety, distinguishing them from other movable properties. However, since transactions such as transfers require registration and procedures similar to those for real estate, cars are sometimes treated as real estate in certain contexts. Movable property refers to objects that can be moved without impairing their economic utility or value, typically including money and goods. Real estate, in contrast, refers to objects that cannot be moved or would lose their economic utility and value if moved, such as land and fixed structures like buildings, bridges, and trees. The distinction between movable and immovable property is based on whether an object can be moved without damaging its value or utility. Movable property can be relocated without such harm, while immovable property cannot. China implements a registration management system for cars and ships, where unregistered transactions cannot be enforced against third parties. This system resembles the registration process for real estate, but cars and ships are not classified as 'real estate.' In civil law, 'objects' refer to material entities existing outside the human body that meet social needs and can be controlled or dominated by people. Objects can be categorized in various ways, including movable vs. immovable, freely transferable vs. restricted, specific vs. generic, principal vs. accessory, divisible vs. indivisible, original vs. derivative, and owned vs. unowned.

What does sel-reset mean in a car?

sel-reset means resetting the mileage counter, and its functions are as follows: 1. After setting the cruise control and accelerating or temporarily canceling the cruise control, pressing RES will restore the previously set speed. 2. Generally, a short press switches between items, while a long press will clear the data. Below are several methods for resetting (clearing): 1. Instrument panel mileage reset: First, adjust the trip computer to the interface that needs to be cleared, then press the button at the top of the wiper for more than 5 seconds, and the mileage will be cleared immediately. 2. Oil maintenance mileage reset: Press and hold the first button (TRIP) under the front display, turn the key to the ON position, and a countdown will appear. When the countdown ends, the maintenance mileage will be automatically cleared. 3. Electronic pedal reset: Without pressing any pedals, turn the key to the ON position (rotate fully but do not start the car), press the accelerator pedal all the way down, then release it, and turn off the key switch. Then, turn the key to the ON position again, wait for the car to complete the self-check, start the car, and the electronic pedal will be cleared. 4. Trip computer (ECU) reset: Disconnect the car battery for at least 2 minutes, then reconnect it. Without pressing any pedals, turn the key to the ON position for at least 30 seconds, then remove the key. Wait for at least 30 seconds, insert the key again and turn it to the ON position, wait for the car to complete the self-check, start the car, and the trip computer (ECU) will be cleared.

What are the symptoms of a damaged shock absorber thrust bearing?

There are four main indicators to determine if a shock absorber thrust bearing is damaged: 1. Abnormal noises: When the shock absorber thrust bearing is severely worn or damaged, the vehicle's shock absorber will produce unusual sounds during operation. 2. Steering deviation: If the shock absorber thrust bearing is damaged, the vehicle's steering may exhibit slight deviation, difficulty in returning to center, and reduced return force. 3. Increased noise: Due to the damaged thrust bearing, the shock absorber will transmit all absorbed vibrations and impacts directly from the chassis to the passenger compartment during operation. 4. Steering noise while stationary: Even when the shock absorber is not in operation, excessive wear or damage to the thrust bearing can cause very noticeable abnormal noises when turning the steering wheel while the vehicle is stationary.

Do I Need to Engage the Handbrake When Shifting to Neutral at a Red Light?

When shifting to neutral (N) at a red light, it is not necessary to engage the handbrake. With the car in neutral, the power output is cut off, making it safe to use the handbrake. If the car is not in neutral, simply pressing the brake pedal is sufficient, as the engine will keep running with the friction plates on the engine side maintaining idle. Additional details: The handbrake, technically known as the auxiliary brake, operates differently from the main braking system. It uses a steel cable connected to the rear brake shoes to apply braking force. Frequent use of the handbrake can cause the steel cable to undergo plastic deformation, which is irreversible and may reduce its effectiveness over time, increasing the handbrake's travel distance. Given its high usage frequency, it is important to use the handbrake correctly and appropriately.
