What are the precautions for changing engine oil?

Precautions for changing engine oil: 1. Pay attention to the model of the engine oil; 2. Pay attention to the amount of oil added. Engine oil, also known as engine lubricant, can lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. Engine oil is composed of base oil and additives. Base oil is the main component of lubricating oil, determining its basic properties, while additives can compensate for and improve the shortcomings of the base oil, giving it certain new properties. Characteristics of engine oil: 1. Lubricity; 2. Low-temperature operability; 3. Viscosity-temperature properties; 4. Oxidation resistance; 5. Anti-foaming properties.

Is it necessary to replace the oil filter when changing engine oil?

When changing engine oil, it is essential to replace the oil filter as well. If you only change the oil without replacing the filter, the new oil will mix with the old oil trapped in the used filter, compromising the lubrication effectiveness of the fresh oil. The oil filter is designed to remove impurities such as dust, metal particles, carbon deposits, and soot from the oil, thereby protecting the engine. There are two types of oil filters: full-flow and bypass. The full-flow filter is connected in series between the oil pump and the main oil gallery, filtering all the lubricating oil entering the main gallery. The bypass filter, on the other hand, is connected in parallel with the main oil gallery and only filters a portion of the oil delivered by the pump.

Is it necessary to replace the oil filter when changing the engine oil?

It is necessary to replace the oil filter when changing the engine oil. The oil filter can filter out impurities in the engine oil circulating in the lubrication system. If the oil filter is not replaced for a long time, it can become clogged due to the accumulation of dirt, allowing contaminants to flow directly into the engine and accelerate component wear. Changing the engine oil without replacing the oil filter will cause the contaminants in the old filter to re-enter the fresh oil circulation, rendering the oil change meaningless. Engine oil is a type of lubricant for the engine. Since engine components are made of metal, without lubrication, metal-to-metal friction can easily cause irreversible damage to the parts. Therefore, it is essential to rely on the engine oil to form a protective oil film on the components for lubrication and protection.

Is a Wheel Alignment Necessary After Replacing Shock Absorbers?

Replacing rear shock absorbers does require a wheel alignment. For instance, if only the left shock absorber is replaced while the right one remains unchanged, the spring forces of the two shock absorbers will relatively differ. The reasons for performing a wheel alignment are: 1. To prevent severe tire wear; 2. To avoid uneven wear between front/rear and left/right wheels causing directional deviation; 3. To prevent the steering wheel from becoming heavier. Wheel alignment adjusts the suspension positioning angles based on the manufacturer's chassis parameters, thereby restoring vehicle stability, steering performance, and traction. The installation of a car's four tires, steering mechanism, and the distance between front and rear axles must maintain specific relative positions, which are standardized values set by the vehicle manufacturer.

Is the Brake Pedal the Foot Brake?

The brake pedal, as the name suggests, is the pedal that restricts power, i.e., the pedal for the foot brake, used for decelerating and stopping the vehicle. Here is some extended information about the electronic parking brake: 1. Electronic Brake: Refers to the technology that integrates the temporary braking during driving with the long-term parking brake function, and achieves parking braking through electronic control. 2. Electronic Parking Brake: Is a technology that realizes parking braking through electronic control. Its working principle is the same as that of the mechanical handbrake, both achieving parking brake control through the friction generated between the brake disc and the brake pads. The only difference is that the control method has changed from the previous mechanical handbrake lever to an electronic button.

Why Do You Have to Wait 10 Days to Reschedule After Failing the Subject 2 Driving Test?

Here are the specific reasons why you have to wait 10 days to reschedule after failing the Subject 2 driving test:1. Large number of candidates: There are many candidates and limited test centers, with each exam slot having a quota. If one person successfully books a slot, another may not.2. Extending the application period: Failing the test extends the time before you can apply again, giving candidates time to review and practice, while also freeing up slots for other applicants. Here is additional information about driver's licenses:1. Purpose: It is a document that certifies the holder is allowed to drive. The full name is "Motor Vehicle Driving License," commonly known as a driver's license, and it is the legal certification required for operating motor vehicles.2. Definition: A motor vehicle driving license is a legal document issued by authorities to individuals who have studied and mastered traffic regulations and driving skills, passed the required tests, and are permitted to drive certain types of motor vehicles.
