Does Mercedes-Benz Antifreeze Need to Be Diluted with Water?

[LeJoel]

Mercedes-Benz antifreeze needs to be diluted with water. The original high-concentration antifreeze has a very high freezing point, so it is necessary to add half the amount of water, meaning the mixing ratio of antifreeze to water should be 1:1. This way, the freezing point of the antifreeze can reach -37°C. Composition of Antifreeze: The main components of antifreeze are: 50% purified 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 Different Antifreezes Be Mixed? The same brand of antifreeze must be used. Different brands of antifreeze may have varying production formulas. If mixed, the various additives may undergo chemical reactions, rendering the additives ineffective. How to Choose Antifreeze: The basic indicators of antifreeze are the freezing point and boiling point. On the market, antifreeze comes in several specifications with freezing points of -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.
