What is motor oil?

Motor oil is a type of lubricating oil. Below are specific details about lubricating oil: 1. Function: Lubricating oil is a liquid lubricant used in various types of machinery to reduce friction between parts and protect machinery and processed components. It primarily serves functions such as lubrication, cooling, rust prevention, cleaning, sealing, buffering, and eliminating impact loads. 2. Composition: Lubricating oil generally consists of two parts: base oil and additives. The base oil determines the fundamental properties of the lubricating oil, while a small amount of additives can compensate for and improve the performance of the base oil. It is typically a product of petroleum distillation, but can also be extracted from animal and vegetable oils. Based on its source, it is classified into three major categories: animal and vegetable oils, petroleum lubricating oils, and synthetic lubricating oils.

What Does the Exclamation Mark Warning Light in the Middle of a Car Mean?

There are five possible scenarios when an exclamation mark appears on the car dashboard: general malfunction, automatic transmission failure, brake system failure, abnormal tire pressure, and lighting system malfunction. Below is a detailed analysis of these five situations: General Malfunction: An exclamation mark inside a triangle indicates a fault in the car's general performance, components, or functions. Common issues include parking sensor failure, fuel cut-off system intervention or malfunction, external light failure, or engine oil pressure sensor malfunction. It is necessary to visit a 4S shop for inspection to identify the source of the problem. Automatic Transmission Failure: A yellow gear with an exclamation mark inside is the automatic transmission warning light, indicating a transmission fault or transmission fluid level below the normal range. Transmission fluid should be replaced promptly. Brake System Failure: An exclamation mark inside a circled parenthesis represents a brake system warning, typically signaling brake system malfunction or low brake fluid level. Immediate inspection of the brake system is required to avoid accidents. Abnormal Tire Pressure: An exclamation mark below a horizontal line inside a parenthesis is the tire pressure monitoring warning light, which illuminates when the car's tire pressure is too low. Check the tire pressure and restore it to the normal range. Lighting System Malfunction: A yellow bulb with an exclamation mark is the lighting system malfunction indicator, signaling a fault in one of the car's lights. Solution: Visit a 4S shop for inspection as soon as possible, or conduct a self-check focusing on commonly used bulbs such as turn signals, fog lights, and interior lighting to identify the issue.

Car transmission maintenance tips: 1. Regularly check for looseness in fasteners and control mechanisms, and tighten or repair them as needed. 2. Due to the difference in external temperatures between winter and summer, use different lubricating oils for each season. The transmission should be cleaned every 500 hours of operation, and new gear lubricating oil should be replaced. 3. Pay attention to the cleanliness of the oil when refueling. When replacing gear oil, drain the old gear oil while it is hot, then add new diesel oil, idle at low speed for 2-3 minutes, finally drain the diesel oil, and add new gear oil. 4.
