Can You Still Drive with Only 10% Oil Left?

You can still drive with only 10% oil left, but it is generally not recommended to continue driving as it can cause more damage to the car. Here is some relevant information about car engine oil: 1. Definition: Engine oil, also known as engine lubricant, serves to lubricate and reduce friction in the engine, assist in cooling, seal against leaks, prevent rust and corrosion, and provide shock absorption. It is often referred to as the 'blood' of the car. 2. Precautions: When removing the oil pan screw, avoid using an adjustable wrench as it can easily strip the screw. Before draining the oil, loosening the oil cap in advance will allow the old oil to flow more smoothly. When tightening the oil pan screw, be mindful of the force applied—just tighten it sufficiently to avoid stripping the threads. Some oil pan screws come with copper washers to prevent leaks, which need to be replaced periodically, and the oil pan screws themselves should also be replaced regularly.

How to Install a Child Seat Without ISOFIX Interface?

If your car does not have an ISOFIX interface, you can use the LATCH interface to secure the child seat. Here is more relevant information: 1. Child seat fixing interfaces: Common child seat fixing interfaces include ISOFIX, LATCH, and seat belt interfaces. Among them, ISOFIX is a hard connection, while LATCH is a soft connection. Compared to the seat belt interface, ISOFIX and LATCH are more stable, and most cars are equipped with ISOFIX and LATCH interfaces. 2. Seat belt interface fixing: The seat belt fixing method requires some skill and can be divided into forward and reverse installation methods, with reverse installation being more suitable for infants. Since the seat belt can get stuck when stretched too long, it is advisable to pull it out completely at the beginning to facilitate subsequent work and avoid insufficient length or getting stuck, which would require restarting the process. Thread the seat belt through the seat and secure it with the seat's red fixing clip. This feature is designed to fix the seat belt and prevent it from sliding, ensuring the seat remains securely in place, then insert the interface.

What are the size specifications for spark plug sockets?

Spark plug sockets come in two size specifications: 16mm and 21mm. The spark plug mainly consists of a terminal nut, insulator, terminal stud, center electrode, side electrode, and shell. As a crucial component of a gasoline engine's ignition system, it introduces high voltage into the combustion chamber, causing it to jump across the electrode gap to generate a spark, thereby igniting the combustible air-fuel mixture in the cylinder. Under high voltage, the air between the spark plug's center electrode and side electrode rapidly ionizes, forming positively charged ions and negatively charged free electrons. When the voltage between the electrodes reaches a certain level, the number of ions and electrons in the gas increases like an avalanche, causing the air to lose its insulating properties. The gap then forms a discharge channel, resulting in a "breakdown" phenomenon. At this point, the gas becomes a luminous body, known as a "spark." Along with thermal expansion, a "crackling" sound is also produced. The temperature of this electric spark can reach as high as 2000-3000°C, sufficient to ignite the air-fuel mixture in the cylinder's combustion chamber.

What Does the Engine Oil Grade Chart Mean?

Engine oil grade chart is a table that categorizes engine oils based on their quality grades and viscosity grades. Below is relevant information about automotive engine oil quality and viscosity: 1. Oil viscosity: Oil viscosity is often indicated using SAE grades, where SAE stands for the 'Society of Automotive Engineers'. Taking 10W-40 as an example, 'W' stands for winter, the number 10 indicates that this oil is suitable for an external minimum temperature of -25°C, and the number 40 indicates resistance to external high temperatures up to 40°C. 2. Oil quality: Automotive engine oils are specifically classified into 4 types for summer use, 6 types for winter use, and 16 types for all-season use, with different qualities and purposes. Summer oils are labeled as 20, 30, 40, and 50, where a larger number indicates higher viscosity and suitability for higher maximum temperatures. Winter oils are labeled as 0W, 5W, 10W, 15W, 20W, and 25W, with the symbol W representing the abbreviation for Winter.

What are the driving tips?

Here are the specific introductions of driving tips: 1. Pay attention to the surrounding vehicles and pedestrians on the road: If pedestrians are blocked by oncoming vehicles, honk immediately to alert them. When meeting oncoming vehicles on a road without a central guardrail, reduce speed, choose a relatively wide section, maintain a speed of 20 to 30 kilometers per hour, and pass slowly in third gear. 2. Sections with poor visibility and lighting: When vehicles meet, reduce speed and turn on the low beam. Even if the road is relatively wide, pass slowly. 3. Do not coast in neutral: Do not coast in neutral by shifting the automatic transmission lever into neutral before a red light or when going downhill, as this can damage the automatic transmission. The gears in the automatic transmission will rotate at high speed driven by the wheels, reaching 3000 rpm in an instant. Due to insufficient oil supply from the transmission oil pump, the gears may not be adequately lubricated, leading to burning and causing the automatic transmission oil temperature to rise, affecting its service life.

Should the Lettered Side of the Piston Ring Face Up or Down?

The lettered side of the piston ring should face up. Below is an introduction to automotive piston rings: 1. Definition: A piston ring is a metal elastic ring with significant outward expansion deformation, which is assembled into a corresponding annular groove. The piston ring, undergoing reciprocating and rotational motion, relies on the pressure difference of gas or liquid to form a sealing and open-ended ring between the outer cylindrical surface of the ring and the cylinder, as well as between the ring and one side of the ring groove. It is divided into two types: compression rings and oil rings. 2. Function: The compression ring in the piston ring serves to seal the gap between the piston and the cylinder, preventing gas leakage. The oil ring functions to scrape off excess oil from the cylinder wall, preventing it from entering the combustion chamber for burning. Additionally, it ensures even distribution of oil on the cylinder wall, improving the lubrication conditions of the cylinder wall surface.
