Why Does the Passenger Side Window Fog Up?

Window fogging occurs simply due to the large temperature difference between the inside and outside of the car. Here are some methods to defog: 1. Use the air conditioning effectively: While driving, you can first turn on the cooling air; if you want a thorough solution, it's best to turn on the heating air before driving or when parked on the roadside until the fog completely disappears. 2. Open windows for air circulation: Based on the principle of fogging, you don't even need to use the air conditioning. Just slightly open both side windows to allow air inside the car to circulate. The advantage of this method is that as the air inside and outside the car circulates, the temperature inside and outside the car will roughly equalize, preventing fogging. 3. Purchase specialized anti-fog products: Anti-fog sprays can be applied to the inside of the windshield and wiped evenly. There are also special anti-fog towels available on the market, which come in dry and wet versions. These towels are more convenient than sprays—just wipe and they work—but their effectiveness is shorter, usually lasting no more than 24 hours.

How Long Does a Minor Maintenance Take?

A minor maintenance typically takes between twenty minutes to an hour. Here are some relevant details: 1. A minor maintenance is recommended every six months or every 5,000 kilometers driven. 2. The scope of a minor maintenance is relatively limited, primarily involving inspections of wear-prone components such as engine oil and the three filters (air, oil, and fuel). Generally, the first maintenance for a car is recommended at 5,000 kilometers or one year of use, while the second maintenance is recommended at 10,000 kilometers or two years of use. The main focus of these services is inspecting the car's three major components: the engine, chassis, and transmission. 3. It is essential to keep detailed records of all maintenance work for future reference if issues arise. Typically, major maintenance should be performed at a 4S dealership, as they offer higher quality assurance despite potentially higher costs. For minor maintenance, you can opt for external auto repair shops, ensuring that original manufacturer fluids are used—this won't harm the vehicle and can significantly reduce costs. However, always choose reputable repair shops and high-quality parts to avoid post-maintenance quality issues.

How to Deal with Low Coolant Level in the Vehicle Radiator?

Solutions for low coolant level in the vehicle radiator are as follows: 1. If it's a pipe leak, go to a repair shop to patch it up or replace the pipe. 2. If the oil cooler sealing ring is damaged or has pinholes, the sealing ring needs to be replaced. 3. If the radiator cap is not sealing tightly, try resealing it. If it still doesn't seal properly, go to a repair shop to replace it. The reasons for low coolant level in the vehicle radiator are as follows: 1. Leakage from pipe joints or the pipe itself—replace the pipe or reinforce the seal. 2. Cracks in the cylinder block, or a loose or damaged cylinder head gasket, causing coolant leakage. 3. Damaged or pinhole-prone oil cooler sealing ring, leading to coolant leakage. 4. The radiator cap is not sealing tightly. 5. Leakage from the heater radiator. 6. Leakage from the three-way connector.

What is the difference between Golden Mobil and Silver Mobil?

Golden Mobil and Silver Mobil differ in nature, quality, viscosity grades, and performance aspects. Different nature: Golden Mobil 1 is a top-tier engine oil, belonging to the 6th generation formula; Silver Mobil is part of the 5th generation formula with average performance. Different quality: Golden Mobil uses Group IV PAO fully synthetic base oil, and its additive formula offers better anti-wear protection and low-temperature performance compared to Silver Mobil. In recent years, many viscosity grades of Silver Mobil have started using MSDW hydroisomerized oil, commonly referred to as Group III+, which is no longer a fully synthetic oil in the true sense. Different viscosity grades: Golden Mobil has five viscosity grades: 0W20, 0W30, 0W40, 5W30, and 5W40, with the 5W series being newly introduced products. Silver Mobil has four viscosity grades: 0W20, 5W20, 5W30, and 5W40. Performance aspects: Due to the different formulas of the two oils, their performance characteristics also vary. Golden Mobil lasts longer and has better fluidity at low temperatures compared to Silver Mobil. It is also more fuel-efficient and delivers stronger power than Silver Mobil.
