How long can a car run without engine oil?

It is not advisable to drive a car without engine oil. The presence of engine oil is crucial for lubricating and cooling the engine. If you force the car to run without oil, the lack of lubrication will cause the engine components to rub against each other, leading to damage. Engine oil serves multiple purposes, including lubrication to reduce friction, aiding in cooling, sealing to prevent leaks, protecting against rust and corrosion, and acting as a shock absorber. Engine oil consists of base oil and additives. The base oil is the primary component of the lubricant, determining its fundamental properties, while additives enhance and compensate for any shortcomings in the base oil, providing additional performance benefits and making them an essential part of the lubricant.

What is the difference between second-generation and fourth-generation car films?

Here is an introduction to the differences between second-generation and fourth-generation car films: 1. Thermal insulation performance: Second-generation films either have high light transmission with poor thermal insulation or good thermal insulation that affects light transmission. Their high reflectivity creates a mirror-like appearance, causing light pollution, and they are prone to oxidation. In contrast, fourth-generation films can largely avoid these drawbacks. 2. Advantages: Second-generation films use new adhesives and thicker layers to improve explosion-proof effects, while fourth-generation films evenly distribute various precious metals on PET substrates through magnetron sputtering technology. They selectively filter visible light while blocking infrared and ultraviolet rays, offering high thermal insulation, high light transmission, high sun protection, low reflectivity, and high toughness, which increases the glass explosion-proof coefficient for safer driving.

What Causes Diesel Fuel to Turn Black?

Diesel fuel turns black due to prolonged storage. Here are some precautions for diesel storage and usage: 1. Prohibited uses: It is strictly forbidden to mix diesel with gasoline for lighting or as fuel for kerosene stoves. 2. Before use: Diesel must undergo sedimentation, filtration, and removal of impurities and moisture before use to ensure the proper functioning of the diesel engine fuel supply system. In winter, it may be necessary to preheat the diesel before use. 3. Mixing: Different grades of diesel within the same classification have basically the same quality indicators except for the freezing point and cold filter plugging point. Therefore, when resources are insufficient, they can be mixed under appropriate temperature conditions.

Is it advisable to purchase used auto parts tires?

It is possible to buy used auto parts tires, but there are risks involved. Below is a detailed introduction to used auto parts tires: 1. Risks: The main risks of purchasing used auto parts tires lie in the inability to accurately assess their quality, manufacturing date, mileage, service life, remaining usable lifespan, remaining usable mileage, as well as stability and safety during use. 2. Identification: Tire tread patterns are divided into longitudinal and transverse patterns. The quality of used auto parts tires should be judged based on factors such as the depth of the tire tread. Additionally, whether the wear is even can also indicate whether the used auto parts tires can be used normally in the future.

Can the Air Conditioning Be Turned On Without Starting the Car?

You can turn on the air conditioning without starting the car, but the air blown out by the blower is just natural air. The natural air blown by the blower is powered by the battery. If the blower consumes too much power from the battery, it may cause the battery to be undercharged for a long time. The air conditioning compressor is driven by the engine's power, so the compressor naturally does not work when the car is turned off. Correct usage of car air conditioning: 1. Open the windows before turning on the air conditioning: After the car has been exposed to the sun in summer, do not rush to turn on the air conditioning upon entering the car. First, lower all the windows or open the doors, then turn on the fan to accelerate air circulation, and finally close the windows and turn on the air conditioning. This helps release toxic substances and provides better cooling effects. 2. Direct the air conditioning upward at an angle: Choose to blow the air upward at an angle, utilizing the principle that hot air rises and cold air sinks, to cool the car from top to bottom. 3. Avoid prolonged low temperatures: While driving, car owners should avoid setting the air conditioning temperature too low, as this will increase fuel consumption. Try to keep the temperature difference between the inside and outside of the car minimal.

Why is overtaking not recommended on downhill slopes?

When driving motor vehicles on downhill sections of mountain roads, overtaking should be avoided as much as possible. This is because vehicles tend to gain excessive speed due to gravitational force on downhill slopes, making them more difficult to control compared to level roads. With gravitational acceleration and reduced resistance on downhill sections, the question inquires about the reasons to avoid overtaking - note that the preceding vehicle's speed is not the primary reason against overtaking. Additional guidelines: Precaution 1: Avoid overtaking as much as possible on mountain roads. When overtaking is necessary, choose wide road sections with gentle uphill gradients, activate the left turn signal, honk in advance, and only proceed after confirming the preceding vehicle yields. Never force overtaking, and strictly prohibit overtaking on narrow roads, sharp curves, continuous turns, or sections with oncoming traffic. Precaution 2: Motor vehicle overtaking must comply with these regulations: No overtaking is allowed at intersections, crosswalks, flooded roads, or submerged bridges. When overtaking on mountain road sections, drivers must: Activate the left turn signal in advance; Sound the horn beforehand; Confirm the preceding vehicle yields before passing.
