What are the reasons for the self-reduction of engine oil?

Engine oil self-reduction is caused by: 1. Aging of cylinders, pistons, or piston rings; 2. Weakened sealing of valve guides; 3. Aging of engine body sealing rings, leading to weakened sealing; 4. Loose bottom oil tank screws. Engine oil is composed of base oil and additives. The base oil is the main component of lubricating oil, determining its basic properties, while additives compensate for and improve the shortcomings of the base oil's performance. It is divided into diesel engine oil and gasoline engine oil. Engine oil, also known as engine lubricant, serves to lubricate and reduce friction, assist in cooling, seal and prevent leaks, prevent rust and corrosion, and provide shock absorption for the engine.

How to Determine if the Battery Still Has Power?

To determine if the battery has power, you can measure its static voltage. A car battery typically has a voltage of 12V, but the actual voltage is slightly higher. When the engine is not running, the voltage measured between the positive and negative terminals using a multimeter should be between 12.5V and 12.8V. If the measured voltage is below 11.5V, it indicates that the battery is low on power. If the voltage is below 10.9V, it means the battery is almost completely depleted. Car batteries are also considered consumable parts. Over time, the battery's capacity to hold a charge gradually decreases, eventually requiring replacement. However, proper maintenance can help extend the battery's lifespan.

How to Change the Coolant in a Sedan?

The steps for changing the coolant in a sedan: 1. Turn off the engine and wait for it to cool down, then open the radiator cap; 2. The radiator drain is located under the car. Lift the car, drain all the coolant, and then close the drain valve; 3. Lower the car, pour new coolant into the radiator filler until coolant starts to overflow, and observe if there are any air bubbles. Once no more bubbles appear, start the engine. The primary function of coolant is to cool, protecting the engine's performance and extending its lifespan. It also has antifreeze, anti-boil, and anti-scale properties. Especially when the outdoor temperature drops below zero, coolant ensures that vehicle components do not fail due to the cold.

How to Identify a Start-Stop Battery?

Methods to identify a start-stop battery: 1. Start-stop batteries have dedicated markings on their appearance, whereas ordinary batteries do not have such specific symbols; 2. Start-stop batteries are heavier in weight compared to regular batteries; 3. When shaking a start-stop battery, there should be no sound of liquid inside. Start-stop batteries are also known as maintenance-free batteries, with AGM and EFB being the two common types currently available, each having different dedicated symbols. Batteries marked with "Valvecontrolled VRLA" or "AGn" are valve-regulated AGM batteries; those labeled with "ST", "N55", "Q85", "S95", "EFB", or "for idle stop system vehicles" are EFB start-stop batteries.
