How to Check Whether the Car's Engine Oil Needs to Be Changed or Not

Methods to check whether the car's engine oil needs to be changed: 1. You can judge by checking the quality of the oil, observing its transparency and color. If the color is clear without impurities or strange odors, it means it can still be used. If the color turns black and has a strange odor, it's time to change the oil; 2. You can check the viscosity of the oil. Dip a little oil on your hand. If it has no stickiness at all on your fingers and feels like water, it means the oil has reached its usage limit and needs to be changed. The main function of engine oil is to reduce friction and wear of moving parts and to remove sludge and paint deposits in the engine.

Can You Sleep in a Car with the Engine Running?

Whether you can sleep in a car with the engine running is explained as follows: 1. No, sleeping in a car with the engine running may cause minor damage to the vehicle, but it can also lead to fatal oxygen deprivation. 2. People should not stay inside a car for extended periods, as inhaling the carbon dioxide and other exhaust fumes produced by the car can lead to poisoning, and once unconsciousness occurs, tragedy may follow. Additional information: 1. When a car is idling in place, you should not stay inside for too long. The exact duration depends on environmental and climatic conditions. With wind, about 15 minutes may be safe, but without wind, do not exceed 5 minutes. Car exhaust contains a large amount of toxic gases, especially carbon monoxide, which is present in higher concentrations during idling. 2. Due to the high density of carbon monoxide, the exhaust emitted from the tailpipe can create a high-concentration zone of carbon monoxide around the car, which can enter the cabin through the air vents and accumulate inside. 3. When the car is stationary, whether you are running the air conditioning, heating, or just idling, you should not remain inside the car for long periods, as this is very dangerous. Prolonged engine idling does not actually have any adverse effects on the engine. If it were truly harmful, manufacturers would include features or warnings to limit idling time, so there is no need to worry excessively about this aspect.

How Long Can a Tire with Cracks Still Be Used?

Tires with minor cracks can still be used temporarily for about a year, as these cracks result from natural rubber aging. Generally, small cracks may appear after 3 to 5 years of tire use. If a tire has been in service for over 5 years, its hardness increases, noise levels rise, and it essentially loses its rubber properties, making it unsafe for continued use—prompt replacement is advised. Another sign of tire aging is tread separation; once pieces start falling off, the remaining tread is likely to follow, significantly reducing the tire's grip. This can lead to dangerous situations such as skidding in wet conditions, reduced acceleration performance, poor cornering traction, and noticeably longer braking distances. To ensure driving safety, immediate replacement is necessary. Tires are circular, elastic rubber products mounted on various vehicles or machinery to roll on the ground.
