How Often Should Motorcycle Engine Oil Be Changed?

Engine oil should be changed every 5,000 to 10,000 kilometers or every six months to a year. Introduction to Engine Oil: Engine oil, also known as engine lubricant, is referred to as Engine-oil in English. It serves multiple functions such as lubrication and friction reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption and buffering for the engine. Composition of Engine Oil: Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of lubricating oil, determining its fundamental properties. Additives are used to compensate for and improve any deficiencies in the base oil's performance, imparting new characteristics, making them a crucial part of the lubricating oil.

What is the principle behind 'ten shakes, nine passes' in straight-line driving?

The principle behind 'ten shakes, nine passes' in straight-line driving is that a car cannot maintain absolute straight-line motion. Therefore, gripping the steering wheel rigidly without adjustments will fail to keep the vehicle moving straight. Only by continuously making minor directional corrections can straight-line driving be maintained. Reasons for inability to drive straight: Cars have a thrust angle determined by various parameters of the rear wheel suspension. As the vehicle is used over time, changes in rear suspension parameters cause the car to develop a thrust angle. The direction of this thrust angle determines which side generates a lateral force, causing the car to deviate from a straight path. Additionally, uneven wear of the four tires, varying tire pressures, and differing suspension parameters mean very few vehicles can maintain perfect straight-line driving. Precautions for straight-line driving: Before entering the test section, shift into fourth gear in advance and increase speed to between 35-40 km/h. This is because at higher speeds, if the vehicle drifts, the required steering correction is smaller. Conversely, at lower speeds, larger steering corrections are needed when the vehicle drifts.

Why are pop-up headlights banned in China?

Pop-up headlights are banned in China to protect pedestrian safety. Introduction to pop-up headlights: Automotive regulations in China are very strict, with laws and regulations restricting car designs. The playful pop-up headlight design has been prohibited due to structural issues with this design. The most classic example is the legendary AE86 that dominated Mount Akina with its pop-up headlights. Nowadays, vehicles with pop-up headlights cannot be driven on roads, as their production has been banned in China. Reasons for banning pop-up headlights in China: To protect pedestrian safety, as pop-up headlights tend to scatter parts upon impact, endangering pedestrians; When colliding with pedestrians, after being knocked down, pedestrians might hit the pop-up headlights again, causing secondary injuries; The structural design of pop-up headlights doesn't comply with aerodynamics, increasing wind resistance; Prolonged use of pop-up headlights can cause jamming, potentially leading to uneven deployment on both sides, creating driving hazards.

How many one-inch photos should I bring after passing Subject 4?

Whether you need to bring one-inch photos depends on the regulations of the local vehicle management office. Some places require you to provide ID photos when registering for the driving test, and these photos will be used for the license after passing Subject 4. Other places collect photos uniformly after passing Subject 4, in which case you need to prepare three one-inch color photos with a white background. Requirements for Subject 4 photos: The photo must be one-inch, taken within six months before applying for the driver's license, with a front-facing, bareheaded appearance; the background must be white; neither men nor women should wear earrings, but those who need vision correction should wear glasses; women's hair should not be loose, and men's hair should not be too long; red clothing and uniforms are not allowed; the expression should be natural, with facial features visible, and a slight smile is acceptable; the head should occupy about two-thirds of the photo. If you want to change the photo, it can be divided into the following two situations: During the driving test or before receiving the driver's license: In these two cases, you can change the photo by logging into the registration website, replacing the photo, and waiting for a three-day review period. After receiving the driver's license: In principle, you cannot change the photo at this stage, but you can use the "lost and reapply" method to modify the photo. This method is time-consuming and labor-intensive, so it is not recommended unless you are particularly concerned about the photo.

Can a Car Driven into a River Be Declared a Total Loss?

Whether a car driven into a river can be declared a total loss depends on the actual circumstances. Because auto damage insurance usually only compensates for vehicle losses caused by natural disasters or accidents, if the actual situation of the car being driven into the river does not fall within the scope of the insurance claim agreement, the insurance company will not compensate for it. The introduction of auto damage insurance is as follows: Introduction: Auto damage insurance is a type of commercial auto insurance where the insurance company compensates within a reasonable range for the damage to the insured vehicle caused by an insurance accident that occurs while the insured or an authorized driver is using the insured vehicle. Function: Auto damage insurance and third-party liability insurance are the basic types of vehicle insurance, mainly compensating for the loss of the insured vehicle and the loss caused to a third party by the use of the insured vehicle.

Is it difficult to schedule a make-up test for Subject 2?

Subject 2 make-up test scheduling is easy. Here is an introduction to Subject 2: Test content for small cars: The C1 test items include five mandatory tests—reverse parking, parallel parking, stopping and starting on a slope, right-angle turns, and curve driving (commonly known as S-curves) (some regions also include a sixth item: highway toll card collection). The C2 test items include four mandatory tests—reverse parking, parallel parking, right-angle turns, and curve driving (commonly known as S-curves). Reference regulations: For the Subject 2 test, if the applicant fails the first attempt, they are allowed one make-up test. If the applicant does not take the make-up test or fails the make-up test, the current test session is terminated, and the applicant must reschedule the test after ten days.
