What Causes a Car to Fail to Start After Prolonged Inactivity?

The reason a car fails to start after prolonged inactivity is due to battery depletion and gasoline deterioration. For long-term parking, it is necessary to start the car periodically or disconnect the black negative cable of the battery to prevent complete battery discharge. Reasons why a car cannot operate after prolonged inactivity: Battery depletion: The battery cannot power the starter motor, ignition coil, or fuel pump. In this case, an external battery is needed to jump-start the car. Gasoline deterioration: Gasoline has a shelf life of about one month. After three to four months, the gasoline actually evaporates and deteriorates, requiring the engine oil to be replaced. Precautions for long-term car inactivity: Pay attention to the "four fluids": The "four fluids" mainly refer to engine oil, brake fluid, coolant, and windshield washer fluid. Among these, engine oil is the most critical. Even if unopened, engine oil undergoes slow oxidation. Starting a car after prolonged inactivity is a significant challenge. When a car is left unused for a long time, most of the engine oil drains back to the oil pan, leaving the upper parts severely lacking oil film protection. During the restart process, the engine experiences severe dry friction, which is when the most wear occurs. Therefore, it is especially important to monitor the condition of the engine oil. Ensure sufficient battery charge: Even if the car is not used, the battery slowly discharges. If left inactive for too long, the battery may deplete to the point where it cannot start the car. If the car is left unused for more than two months, it is best to disconnect the negative terminal of the battery (only the negative terminal; the positive terminal does not need to be touched). Chassis precautions: First, maintain proper tire pressure. To prevent localized tire deformation during prolonged parking, the car should be parked on a flat surface, and the tire pressure should be slightly increased—around 2.8 BAR for both front and rear tires. Second, a thorough chassis inspection is essential. Check for oil leaks in areas such as the CV joints, transmission, shock absorbers, and oil pan. If leaks are found, they should be addressed before long-term parking. Rust prevention is critical: Rust prevention mainly applies to damaged paint on the car body. Even minor paint damage, if left untreated, can lead to rust spreading and potentially corroding through the metal. If rust spots are present, they should be covered with toothpaste or a touch-up pen to prevent further expansion. This is an important step before long-term parking.

What are the consequences of not changing engine oil?

The effects of not changing engine oil for a long time: 1. Engine oil primarily serves to lubricate the engine. If not changed for an extended period, the oil can become ineffective and deteriorate, which will significantly increase engine wear. In severe cases, it may even lead to engine seizure. 2. Another critical function of engine oil is cleaning. If the oil is compromised, it cannot effectively remove impurities (such as carbon deposits and metal particles) that form on the working surfaces of engine components. Over time, this not only affects heat dissipation and lubrication but can also clog oil passages, leading to engine damage or even complete failure. Diesel engines may experience even harsher operating conditions. 3. The cooling efficiency of the oil will decline, negatively impacting various car components. Particularly vulnerable parts may sustain damage or even burn out over time.

How Does the Oil Film on the Windshield Form?

Car glass oil film is formed due to exposure to oil stains and dust in the air, and not being thoroughly cleaned for a long time, leading to the formation of an oil film. Methods for removing oil film from the windshield: The oil film is very stubborn and cannot be completely removed by ordinary car washing. Special oil film removers and soft cloth wiping are required for thorough cleaning. Precautions to avoid oil film formation: When parking, try to choose a relatively empty parking space, avoiding areas under trees or near hotel exhaust pipes, as chewing gum, bird droppings, and kitchen fumes are the most significant factors in oil film formation. If the vehicle is not used for a long time, purchasing a car cover to protect the body can be very effective.

What is the Definition of a New Car vs. a Stock Car?

Stock cars generally refer to vehicles that have not been sold for more than three months after leaving the factory. There are two common types of stock cars: those that have spent the stock period in the manufacturer's warehouse and those that have spent the stock period in the dealer's warehouse. When purchasing a stock car, it is essential to carefully inspect the vehicle's condition. Here are some methods to identify a stock car: 1. Check the production nameplate: Located below the B-pillar on the right side of the vehicle, the nameplate displays the production date and engine parameters. 2. Examine the glass: The production date and year of the glass are marked on the car windows. 3. Inspect the tires: Determine the production time by checking the tire's manufacturing date. 4. Look under the hood: Open the engine compartment to check if the engine is clean.

What's the Difference Between Four-Wheel Drive and Two-Wheel Drive?

Two-wheel drive (2WD) vehicles refer to those where only two wheels are responsible for driving the vehicle's movement. Front-wheel drive (FWD) means the two front wheels are responsible for driving, while rear-wheel drive (RWD) means the two rear wheels are responsible for driving. Four-wheel drive (4WD) vehicles refer to those where all four wheels have driving functionality. Full-time 4WD means all four wheels are always in driving mode. Part-time 4WD allows the driver to manually switch between 4WD and 2WD. Automatic 4WD means the switching between 4WD and 2WD is controlled by the vehicle's onboard computer. The main differences between 2WD and 4WD are as follows: 1. Power Performance: Since all four wheels are driving wheels, 4WD vehicles have a significant advantage in climbing hills, starting, and accelerating, making them more powerful. 2. Handling: Front-wheel drive vehicles tend to understeer, while rear-wheel drive vehicles tend to oversteer. 4WD vehicles offer better handling. 3. Off-Road Capability: 4WD vehicles have better off-road capability. Even if 1-2 wheels lose traction, the other driving wheels can still pull the vehicle out of difficult road conditions. 4. Fuel Efficiency: 2WD vehicles are more fuel-efficient because 4WD vehicles have more complex drivetrain structures, resulting in greater power loss. Additionally, their drivetrain components, such as the transfer case and extra differential, are heavier, which increases fuel consumption. 5. Cost: 4WD vehicles have more complex drivetrain structures, leading to higher manufacturing costs. Their drivetrain components also require maintenance, making 2WD vehicles cheaper to maintain.
