Is There a Difference Between Different Colors of Antifreeze?

[SanLucille]

Antifreeze comes in different colors, which only indicate different compositions, but their effectiveness is the same. In other words, there is no fundamental difference between antifreeze of different colors. The variation in color is mainly due to differences in formulations among manufacturers. Essentially, antifreeze is transparent, but manufacturers add various additives to give it color. The purposes of this are as follows: 1. To distinguish it from other liquids. 2. To help users differentiate when selecting antifreeze, preventing the mixing of different antifreeze types, which could harm the engine. 3. For safety reasons, serving as a warning. In most people's perception, brightly colored liquids are generally toxic, so their chemical composition also makes them look visually striking, reminding people that these liquids are toxic and should not be ingested to avoid poisoning. 4. It is particularly important to note that antifreeze of different colors should not be mixed. The chemical reactions between different additives may produce gummy substances, leading to sedimentation, scaling, and corrosion, rendering the antifreeze ineffective and, in severe cases, damaging the engine.
