DOT3 brake fluid offers better overall performance. Although DOT4 and DOT5 brake fluids have superior hydraulic transmission properties, their moisture absorption and corrosion resistance are less stable compared to DOT3. Additionally, DOT3 is more compatible with the rubber hoses and seals in the braking system. Below are specific details about Toyota: 1. Historical Background: Toyota Motor Corporation is a Japanese multinational automotive manufacturer listed on the Tokyo Stock Exchange (TYO), Nagoya Stock Exchange (NAG), New York Stock Exchange (NYSE), and London Stock Exchange (LSE).

Do You Need to Turn on AC in Winter?

If the windshield fogs up severely in winter, you can turn on the AC. The AC is the cooling switch of the car's air conditioning system, and it is not necessary to turn it on in other situations. The car's air conditioning is an important comfort feature that can provide both cooling and heating. During winter and summer, the car's air conditioning is used almost every day. When the car's air conditioning is in cooling mode, the compressor clutch engages, and the engine drives the compressor to operate. While running, the compressor continuously compresses the refrigerant and delivers it to the evaporator. Inside the evaporator, the refrigerant expands and absorbs heat, cooling the evaporator. The cooled evaporator then cools the air blown by the blower, allowing the car's air conditioning vents to blow cold air.

How Long Can Maintenance-Free Batteries Last?

Quality maintenance-free batteries can typically last effectively for 1-4 years under normal conditions in base stations. Below is a detailed introduction about maintenance-free batteries: Features and Performance: Sealed maintenance-free batteries adopt the fully sealed structure designed in the 1990s and modern production processes. This gives them outstanding performance characteristics such as high efficiency, long lifespan, pollution-free operation, maintenance-free use, and safety reliability. Usage Conditions: Quality maintenance-free batteries can typically last effectively for 1-4 years under normal conditions in base stations. After 1-4 years, their capacity usually gradually declines. Special Cases: Some maintenance-free batteries in base stations may experience rapid capacity degradation and shorter lifespans even after relatively short periods of use.
