Can Car Antifreeze Be Mixed and Topped Up?

[SanAnthony]

Only antifreeze of the same brand can be mixed and topped up in a vehicle. Different brands of antifreeze may have varying production formulas, and mixing them could lead to chemical reactions between multiple additives, rendering them ineffective. Methods for selecting antifreeze: The basic indicators of antifreeze are its freezing point and boiling point. On the market, antifreeze comes in several specifications 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 is likely due to low antifreeze levels, though it could also be caused by excessively high engine temperature. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving; promptly top up the antifreeze. Check the water level markings on the antifreeze tank. The antifreeze level should normally be between the maximum and minimum marks. To determine if antifreeze is low, observe the markings. If the antifreeze level is below the minimum mark, it indicates a deficiency.
