Can antifreeze of the same color be mixed?

[DiCollin]

Antifreeze of the same color cannot be mixed; it is necessary to use the same brand of antifreeze. Different brands of antifreeze may have varying production formulations, and if mixed, chemical reactions may occur between multiple additives, rendering them ineffective. The basic indicators of antifreeze are the freezing point and boiling point. On the market, antifreeze is available with freezing points such as -15°C, -25°C, -30°C, and -40°C. It is generally advisable to choose an antifreeze with a freezing point at least 10°C lower than the lowest temperature in your region. Antifreeze replacement cycle: For vehicles that operate for long periods, such as taxis, high-quality antifreeze should generally be replaced once a year. For vehicles with shorter operating times, replacement can be done every two years or every 30,000 kilometers. To prevent excessive foam formation, which can reduce the heat exchange efficiency between the antifreeze and engine components, ensure that the product is within its validity period when adding it. Long-life antifreeze can have a validity period of up to three years. If suspended matter, sediment, or signs of deterioration or discoloration are found in the antifreeze, the system should be promptly cleaned and the antifreeze replaced.
