Does a negative oillife matter?

When the car's oillife turns negative, it indicates that the lubrication capability of the engine oil has significantly decreased, and the oil should be replaced promptly. Below is relevant information about engine oil: Introduction: Engine oil, also known as engine lubricant, has a density of approximately 0.91×10³ (kg/m³). It serves multiple functions for the engine, including lubrication and wear reduction, auxiliary cooling, sealing and leak prevention, rust and corrosion protection, as well as shock absorption. It is often referred to as the 'blood' of the car. Engine oil consists of two main components: base oil and additives. The base oil is the primary constituent of the lubricant, determining its fundamental properties, while additives compensate for and enhance the shortcomings of the base oil, providing additional performance characteristics. Classification: Engine oils in the market can be broadly categorized into mineral oils and synthetic oils based on their base oil (vegetable oils are not considered due to their rarity). Synthetic oils are further divided into full synthetic and semi-synthetic.

I once encountered a situation where the oil life indicator showed a negative value, which I noticed during my daily commute. The system issued a warning stating that the oil had exceeded its service life, prompting me to immediately check the manual. A negative oil life reading indicates that you've surpassed the recommended change interval, which is no trivial matter. Continuing to drive under such conditions can lead to insufficient engine lubrication, increased wear, potential carbon buildup, or even oil burning. In severe cases, it might leave you stranded on the road. On that occasion, I promptly visited a professional workshop to replace the oil and filter—it cost me some money but was absolutely worthwhile. I recommend you immediately check the oil dipstick to verify the oil level and schedule a replacement as soon as possible. Regular maintenance is crucial; I make it a habit to check my oil monthly to prevent similar issues.

Can You Slam the Accelerator with a CVT?

CVT transmissions should not be subjected to sudden, aggressive acceleration. For automatic transmission vehicles, theoretically, the deeper you press the accelerator, the faster the speed increases. However, CVT transmissions do not have a gear structure; instead, they use a metal chain and pulleys for power transmission. When subjected to excessive load, the chain can slip, causing the engine to rev without proper power transfer, which may damage the engine. A CVT, or continuously variable transmission, is characterized by its lightweight, compact size, and fewer components. Prolonged aggressive driving behaviors such as driving at excessively high speeds in low gear, driving at low speeds in high gear, sudden acceleration, and hard braking fall under the category of abusive driving for CVT transmissions. Extended periods of such driving can lead to issues like increased oil consumption, and in severe cases, may cause brake pad overheating, reduced braking efficiency, cylinder scoring, or even engine seizure.

How Many Days to Receive Notification for Highway Reversing Violation?

Highway reversing violations are typically notified within three days through SMS, postal mail, or email to the vehicle owner. According to relevant regulations, reversing or driving in the wrong direction on a highway not only results in a fine but also deducts 12 points from the driver's license. The offending driver must participate in road safety training and exams organized by traffic authorities. Only after passing the exam can the driver regain their driving privileges. If the exam is failed, the driver must continue studying and retaking the exam until they pass. If a driver misjudges the direction and misses an intended exit or junction, they must not reverse. Instead, they should continue driving to the next exit, leave the highway, and then plan a new route to return to the desired exit.

Can a Damaged Sidewall Be Repaired?

The sidewall is the weakest part of a tire. Generally, once a car tire's sidewall is damaged, it cannot be repaired, which is different from damage to the tire tread. Secondly, whether to continue using the tire or replace it depends on the specific situation. The judgment methods are as follows: 1. During parallel parking, improper observation or operation may cause the tire sidewall to come into contact with the curb, resulting in damage. Such minor scrapes usually have little impact on the tire sidewall. If there is no significant surface damage, you can continue using the tire, but you must pay extra attention to its condition. Replace it immediately if air leakage occurs. 2. If you encounter potholes while driving at high speed and cannot avoid them in time, the tire sidewall may suffer significant pressure and tear. In this case, replacement is strongly recommended. 3. When low-profile tires are impacted, the sidewall may bulge. A bulging tire poses a serious safety hazard, as it can blow out at any time and compromise driving safety. Therefore, it must be replaced.

What Does a Major Car Service Include?

Major car service includes the following items: 1. Engine oil - Currently, there are three types of engine oil: mineral oil, semi-synthetic oil, and fully synthetic oil. If using mineral oil or semi-synthetic oil, the regular maintenance interval is around 5,000 kilometers. For fully synthetic oil, the regular maintenance interval extends to approximately 8,000 kilometers. 2. Fuel filter - It filters out water and impurities from the fuel, providing clean fuel. 3. Transmission fluid - The maintenance cycle for transmission fluid ranges between 20,000 to 40,000 kilometers. However, many people only replace it during major services, which is not appropriate. Deteriorated transmission fluid reduces lubrication effectiveness and accelerates transmission damage.

What is a Power Window Closer?

A power window closer is a device that automatically closes the windows for the car owner when they forget to do so after exiting the vehicle. It is also known as an automatic window closer, designed to prevent forgetful car owners from leaving their windows open, which could lead to car theft. The power window closer is also referred to as a window closer, car automatic window closer, car power window closer, or car automatic power window closer. Three modes of the power window closer: 1. Automatically starts closing the windows immediately after the car key is turned off and removed. 2. Automatically starts closing the windows after the car key is turned off and removed, and the driver's door is closed. 3. Automatically starts closing the windows when the remote control is pressed after the car key is turned off and the door is closed. Standard sequence for window closing by the power window closer: The driver's window, the front passenger window, the rear passenger window on the front passenger side, and the rear passenger window on the driver's side are closed in sequence. Car owners can choose the appropriate automatic window closing mode and sequence based on their needs.

What are the penalties for driving on the emergency lane on the highway?

Driving on the emergency lane on the highway will result in a fine and a deduction of 6 points. The emergency lane is a special lane on the highway, only allowed for vehicles such as police cars, fire trucks, and ambulances when performing emergency tasks. When there is no emergency, social vehicles illegally occupying the emergency lane, whether parked or moving, are considered illegal. If there are other violations, the penalties will be cumulative. If the vehicle cannot move due to a breakdown and stops on the lane, the hazard warning lights must be turned on, and a warning sign should be placed 150 meters behind the vehicle. During nighttime, rain, fog, or other adverse weather conditions, the side marker lights, tail lights, and rear fog lights should also be turned on. Other occupants should quickly evacuate the emergency lane and promptly call the highway emergency assistance number.
