It is unsafe to drive when the car engine oil level is below 25%. The reasons are as follows: 1. Insufficient engine oil: This can cause the engine to overheat and lead to wear. 2. Requirement: When the oil level is below 25%, it has already dropped below the minimum mark on the dipstick, making it unsafe to drive. 3. Component damage: Insufficient oil increases gear friction and heat, which can easily cause damage to the gearbox. Relevant information about engine oil is as follows: 1. Engine oil: It is the lubricating oil used by the engine, composed of base oil and additives. 2. Function: With a density of approximately 0.91×10³ (kg/m³), engine oil lubricates and reduces friction, assists in cooling, seals against leaks, prevents rust and corrosion, and provides shock absorption. It is known as the 'blood' of the car. Base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil, providing new properties and serving as an important part of the lubricating oil.

What causes the foul smell in the Dongfeng Fengshen AX7 air conditioning?

Dongfeng Fengshen AX7 air conditioning foul smell reasons: 1. When an air conditioning system that has not been used for a long time is turned on, it may produce an unpleasant odor. This is because the condensed water retained on the heat exchange coils, fins, and surrounding components slowly evaporates, creating a high-temperature environment around the coils that is conducive to microbial growth. The large amount of gas produced during microbial reproduction is then released by the air conditioning system, becoming the source of the foul smell. 2. If the air conditioning has been running for an extended period, dust can accumulate in the filters and copper tubes, and the spaces between the heat exchanger fins can also become filled with dust. When this accumulation reaches a certain level, it can cause blockages and produce a certain odor. When the air conditioning is turned on, this odor is dispersed into the air through the vents. 3. After the air conditioning operates in cooling or heating mode, moisture often remains inside the system. If the air conditioning is turned off immediately without a drying or anti-mold function, this internal moisture persists. Over time, mold can develop, leading to the natural production of a musty smell.

Does it matter if a piece of the tire tread is missing?

Yes, it matters. The thickness of tires is carefully designed to meet specific requirements. If a piece of the tire tread is missing, it can affect tire pressure, and in summer, this may lead to issues with increased tire pressure. Additionally, it can pose safety hazards when driving at high speeds. Tire replacement indicators: 1. Tire wear: Tires have tread wear indicators, which are slightly raised marks located at the bottom of the tread grooves. If the tread rubber wears down to the same height as these raised indicators, the tire should be replaced immediately, as continued driving is no longer safe. 2. Tire damage: Hitting curbs, falling into potholes, or punctures from nails can cause severe tire damage. Damaged tires may sometimes be repairable, but only a professional repair shop can accurately determine whether a tire can be repaired or needs to be replaced. 3. Tire aging: If you notice tread deformation or significant cracking, stop using the tire immediately and have it inspected by a professional repair shop to determine whether it can still be used. 4. Tire bulges: Bulges in the tire are a major cause of blowouts, especially on highways, and are extremely dangerous. Tires with bulges should be replaced promptly.
