What are the Five Oils, Four Filters, and Three Fluids in a Car?
2 Answers
Here is a detailed introduction to the five oils, four filters, and three fluids in a car: 1. Five oils: Refers to five types of fluids—gasoline, engine oil, transmission fluid, brake fluid, and power steering fluid. 2. Four filters: Oil filter, air filter, cabin air filter, and fuel filter. 3. Three fluids: Windshield washer fluid, coolant, and battery fluid. Below is an extended introduction to car maintenance items: 1. Engine oil and oil filter replacement: Primarily pertains to the lubrication system's maintenance. The main function of the lubrication system is to effectively lubricate various components of the car engine to prevent excessive wear. The oil filter's role is to remove impurities from the engine oil, ensuring the lubrication system operates normally. The oil filter should be replaced along with the engine oil during an oil change. Under normal circumstances, a car requires maintenance every 5,000 kilometers. 2. Filter replacement: The air filter's function is to filter air before it enters the cylinders, removing impurities such as dust, sand, and other foreign particles. The cleaning and maintenance of the air filter depend on the usage environment. The fuel filter is typically replaced after driving 20,000–25,000 kilometers. 3. Spark plug replacement: Spark plugs are consumable parts and should be replaced every 20,000 kilometers. Additionally, components such as brake fluid, transmission fluid, battery, throttle body, fuel injectors, and brake pads are all part of the inspection items during routine maintenance, with maintenance performed as needed based on usage conditions.
After driving for over a decade, I've found that the 'five oils, four filters, and three waters' are the core elements of car maintenance. The five oils include engine oil, responsible for lubricating the engine; transmission oil, aiding in smooth gear shifting; brake fluid, used in the braking system; power steering fluid, making steering easier; and differential oil, enhancing four-wheel-drive performance. The four filters are the air filter, which filters incoming air; the oil filter, cleaning impurities from the engine oil; the fuel filter, purifying the gasoline; and the cabin air filter, ensuring air quality inside the car. The three waters are the antifreeze coolant, preventing engine overheating; windshield washer fluid, for cleaning the windows; and battery water, used in older-style batteries. Regularly replacing these can prevent sudden breakdowns. For example, last week I changed my old engine oil, and the car runs noticeably quieter now. This also extends the engine's lifespan, saving money and hassle. Developing a habit of checking these monthly is quite simple.
