Can Expired Windshield Washer Fluid Still Be Used?

Expired windshield washer fluid cannot be used. No matter how high-quality the fluid is, it becomes ineffective once it deteriorates. When purchasing windshield washer fluid, car owners should first check whether the product has exceeded its expiration date. Secondly, they should inspect the fluid for any sediment, as its presence indicates that the fluid has deteriorated. High-quality windshield washer fluid is made from deionized water and various environmentally friendly additives, offering functions such as cleaning, antifreeze, anti-static, and anti-corrosion. Some windshield washer fluids also feature rapid snow and ice melting, anti-glare, and anti-fog properties, which play a significant role in improving driving safety. Low-quality windshield washer fluids are mostly diluted with water and alcohol, which not only damages the gloss of the car's paint and the hardness of rubber seals but can also cause discoloration or swelling of rubber or plastic parts in severe cases.

What causes the windshield to become blurred after using a degreaser?

The windshield, after prolonged exposure to sunlight, heavy rain, wind erosion, etc., develops a microscopically rough surface with numerous pores or pits on the surface. Various oily substances, car waxes, and dust from daily driving can easily adhere to this roughened windshield surface. Specific solutions are as follows: 1. Soap water: Use household soap water to scrub the windshield once, removing the actual oil film layer on the glass surface and washing away ordinary dust layers, which helps in further cleaning. 2. Hot soap water: Soak and wash with hot soap water. If regular cleaning doesn't suffice, then hot water should be used for soaking and cleaning. Hot water provides thermal energy to molecules, causing them to move more vigorously, which can break van der Waals forces and hydrogen bonds, ultimately removing the physical adsorption layer. 3. Use specialized cleaners: Scrub with a hydrochloric acid solution. Hydrochloric acid is a strong acid that can dissolve and decompose most organic or inorganic substances, including metal oxides, without affecting the glass. This is because the main component of glass, sodium silicate, is only soluble in hydrofluoric acid and strong bases.

What is the maintenance interval for Porsche?

Minor maintenance generally refers to the routine maintenance items performed when the vehicle has traveled approximately 8,000 kilometers, or at the time or mileage specified by the manufacturer, to ensure vehicle performance. It mainly includes oil and oil filter replacement, following standard maintenance rules and the three-filter system. The timing of minor maintenance depends on the effective duration or mileage of the oil and oil filter used. More accurately, it depends on the vehicle's driving power and distance traveled. Below are the items involved in minor maintenance: 1. Engine oil is the lubricant for engine operation. It lubricates, cleans, cools, seals, and reduces friction in the engine. It plays a significant role in reducing wear on engine components and extending their service life. Engine oil functions like blood in the human body, providing circulation and lubrication. 2. The oil filter is the component that filters the engine oil. Engine oil contains a certain amount of gum, impurities, water, and additives. During engine operation, metal particles generated by component friction, impurities from the intake air, and oil oxidation products are all filtered by the oil filter. If the oil is not filtered and directly enters the oil circulation system, it will adversely affect the engine's performance and lifespan.

What Scratches Can Repair Wax Fix?

Repair wax can fix scratches on car paint, but only those that have not damaged the primer (i.e., the color paint). Here are the relevant details: 1. Features: Quickly removes minor scratches on the car paint surface, effectively addresses oxidation issues such as dullness, whitening, and fading, and provides a three-in-one formula for repair, polishing, and protection. While swiftly addressing minor paint issues, it also delivers a classic, legendary shine and care for the car paint. Suitable for all types of car paint, including modern metallic finishes, it is an ideal choice for car paint that is not frequently waxed or is exposed to polluted environments. 2. Precautions: Only suitable for seamless surfaces like car paint, metal, plastic, and glass. Should not be used under direct sunlight or when the car body is overheated. Store in environments between 0°C and 40°C (Celsius) and avoid prolonged exposure to sunlight. Contains petroleum distillates—keep away from children and fire sources, and avoid use or storage in high-temperature environments. Do not allow contact with eyes or mouth. In case of accidental contact, rinse thoroughly with plenty of water and seek medical attention immediately.

Should New Cars Be Parked with Windows Closed or Open?

Open the windows. Ventilating a new car is highly beneficial for removing odors, not only eliminating the peculiar smells of a new vehicle but also allowing fresh air to circulate inside, which greatly aids the overall air circulation within the car. Here are some relevant details: 1. Benefits of opening windows for ventilation: Exposing a new car to sunlight is intended to accelerate the mobility of formaldehyde molecules, thereby helping to dissipate the formaldehyde gas retained inside the car. However, this doesn't mean the car should be left in continuous direct sunlight, as prolonged exposure can accelerate the aging of interior upholstery and even release more harmful gases, which would be counterproductive. 2. Precautions when opening car windows: While driving, avoid opening all windows simultaneously as this can cause chaotic airflow inside the car. Small items placed inside the car can easily be blown over by the strong airflow, potentially causing damage or injury. It is also advisable not to open windows when driving on highways, as doing so is undesirable from various perspectives including fuel consumption, noise, and safety. Additionally, when using the air conditioning, it's important to balance the use of internal and external air circulation to ensure adequate air exchange inside the vehicle.

Is 15 kilometers normal for a new car?

If you purchase a joint-venture or domestic brand car, it is generally expected that the mileage of a new car should be very low, possibly within 10 kilometers. This is because new cars are now transported by large car carriers directly to the warehouse, and the distance driven from the factory to the 4S dealership is inherently very short. A dashboard display of 15 kilometers should still fall within the normal and reasonable range. Below are some considerations when buying a new car: 1. Determine the vehicle type: If your budget is limited and you have a large family, it is recommended to prioritize MPV models, with sedan models as the secondary option. Once you have decided on the type of car you want to buy, proceed to select the vehicle on major automotive software platforms. First, choose models with suitable prices, then compare important features such as safety configurations, reputation, fuel consumption, and functional configurations. 2. Inspect various aspects: Verify the displacement, manufacturing date, chassis number, and engine number. Then, inspect the exterior of the car, including the paint, tires, headlights, and taillights, for any defects. Sit in the driver's seat to check if the interior seats are intact and free from flaws, ensure the floor is clean and well-sealed. Test the door handles for smooth, secure, and reliable operation when opening and closing, and check if the door and window seals are damaged.
