What are the five oils and three fluids?
1 Answers
The five oils in 'five oils and three fluids' refer to: engine oil, transmission fluid, fuel, brake fluid, and power steering fluid. The three fluids refer to: windshield washer fluid, coolant, and battery fluid. Engine oil: Its main function is lubrication, along with cooling, sealing, rust prevention, and shock absorption. The replacement interval mainly depends on the oil type. Conventional mineral oil can be changed every 5,000 kilometers, while synthetic oil can be extended to 8,000 to 10,000 kilometers. Transmission fluid: Transmission fluid is used to lubricate and cool the transmission. It is generally recommended to replace it every 60,000 kilometers. Fuel: Fuel lubricates and cools the engine, protecting it. When the oil level is low, it must be replenished promptly. Brake fluid: As the name suggests, it transmits pressure evenly during braking to achieve braking. It has four main functions: energy transmission, heat dissipation, anti-corrosion and rust prevention, and lubrication. Power steering fluid: A special liquid used in the car's power steering pump. It is generally recommended to replace it every 30,000 kilometers. Windshield washer fluid: Cleaning water for the wipers. In principle, tap water can be used, but sediment in homemade washer fluid may clog the nozzles. Battery fluid: Most cars on the market today come with maintenance-free batteries that do not require water addition. To check the battery, simply look at the color in the inspection window to determine its condition. Coolant, short for antifreeze coolant, is a cooling liquid with antifreeze properties. It prevents the coolant from freezing and expanding in cold winter conditions, which could crack the radiator or damage the engine block or cylinder head.
