1 Answers
When selecting car antifreeze, it is important to pay attention to the basic indicators of antifreeze: freezing point and boiling point. The market offers antifreeze with various freezing points such as -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose one that is at least 10°C lower than the lowest temperature in your region. Composition of antifreeze: The main components of antifreeze are: 50% pure water, 40% methanol, and 10% other substances. Types of antifreeze: Antifreeze is generally divided into three types: ethanol-water type, glycerol-water type, and ethylene glycol-water type. Can antifreeze be mixed? It is necessary to use the same brand of antifreeze. Different brands of antifreeze may have different production formulas. If mixed, multiple additives may undergo chemical reactions, causing the additives to become ineffective.
