What is class G12 and what is its feature?
G12 antifreeze contains ethylene glycol; most often manufacturers color it red, pink and orange. This class copes well with corrosion in the cooling system and has a service life of up to 5 years, this is achieved due to the complete absence of silicates. Thanks to these advantages and affordable price, this class has almost completely replaced the more outdated G11 class
.
If you are the owner of a new Japanese car and are thinking about which coolant to choose, G11 or G12. We will make you happy, G11 is not suitable for new cars
!
There is another more modern subclass of this antifreeze: G12+ and G12++. They have a higher quality and improved composition, their service life is up to 8 years, and some types of G12+ can generally be mixed with others. What is the difference between G12 antifreeze and G12+ and G12++? Modern subclasses have many more advantages; there is no point in comparing them.
Let's move from words to action, we have compiled for you a rating of the best g12 class antifreezes in 2020!

It contains special components that minimize the impact of friction on vehicle elements. This allows you to extend the life of vehicle parts, primarily the engine and pump. It is produced on the basis of a number of organic acids.
Advantages:
- Operates over a wide temperature range – from -40 to +110 degrees;
- Creates a protective film on the engine that prevents corrosion and other destructive processes;
- The composition contains only organic substances that do not form sediment during operation.
Flaws:
- When the temperature drops, it becomes too viscous, which makes circulation through the cooling system difficult.
