Can Red Antifreeze Be Mixed with Different Brands?

[VonGrace]

Red antifreeze cannot be mixed with different brands. It is essential to use the same brand of antifreeze. Different brands of antifreeze may have varying production formulas, and mixing them can lead to chemical reactions between multiple additives, potentially rendering the additives ineffective. Methods for selecting antifreeze: The basic indicators of antifreeze are its freezing point and boiling point. The market offers antifreeze with freezing points such as -15°C, -25°C, -30°C, and -40°C. Generally, it is advisable to choose an antifreeze with a freezing point at least 10°C lower than the lowest temperature in your region. Methods to determine if antifreeze is low: Observe the antifreeze warning light on the dashboard. If it lights up, it likely indicates low antifreeze levels, though it could also be due to excessively high engine temperatures. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving; promptly add antifreeze. Inspect the water level scale on the antifreeze tank. Normal antifreeze levels should be between the maximum and minimum marks. If the antifreeze is below the minimum mark, it indicates a deficiency.
