Under normal circumstances, antifreeze cannot be mixed and added. Different brands may have different components, and antifreeze has different colors. The components of different colors are also different, and they cannot be mixed and added. If the car mechanic says that it can be mixed, then the ingredients in the two mixed antifreezes recommended by the master may be the same, and they can be mixed at this time.
1. Try not to mix antifreeze of different brands, because different brands of antifreeze mean different ingredients. Of course, it cannot be ruled out that the brand is different but the ingredients are exactly the same, in which case it can be mixed. But if the ingredients are not the same, do not mix and use, not only will not achieve the desired effect, but will have a worse impact on the car.
2. Try not to mix antifreeze of different colors. Even if antifreeze of different colors is a brand, it will have different ingredients. For example, the main component of red antifreeze is propylene glycol, and the main component of green antifreeze is ethylene glycol. If these two are mixed together, it will also affect the use of the car engine or other parts.
In theory, they cannot be mixed, but as long as the ingredients are the same, we can mix them. However, because we may not know much about the various ingredients, it is best not to try this by ourselves. If we go to the repair shop, professional masters may be more familiar with each ingredient and can help us mix well.
