All You Need to Know About Antifreeze - How to Choose the Best Antifreeze
When choosing antifreeze, you should pay attention to the type of product rather than its color. Because by adding color to the antifreeze, the kind of antifreeze can be manipulated by the seller.
Although strict rules determine the antifreeze standards, some companies may put misleading products on the market to reduce the antifreeze prices.
Inorganic Antifreeze (IAT-Inornagic Acid Technology)
- It is usually light, bright green.
- Contains phosphate (iron preservative) and silicate (aluminum preservative).
- It prevents corrosion in vehicles with the iron engine block, aluminum air circulation pump, cylinder head, and parts where the coolant passes.
- Its average life is 40,000-50,000 km, two years.
Organic Antifreeze (OAT-Organic Acid Technology)
- It can be in many different colors, especially orange, pink, dark green.
- It contains 2-EHA acid and some organic acids.
- Since it does not contain phosphates and silicates, it cannot provide as strong corrosion protection as inorganic antifreeze.
- It penetrates the engine late but provides long-term protection.
- Its average life is 200,000 km, five years.
Hybrid Organic Antifreeze (HOAT-Hybrid Organic Acid Technology)
- It is a mixture of organic and inorganic antifreeze.
- It can be red and pink, predominantly yellow and orange.
Nitrided Organic Antifreeze (NOAT-Nitrited Organic Acid Technology)
- It is usually red and dark pink.
- Organic antifreeze is produced by adding components such as nitrite and molybdenum.
- Its lifespan can be up to 1 million km.
- It is more expensive than other antifreeze.
- It is mainly used in construction machines and commercial vehicles that make a lot of distance quickly.
How will you decide?
Before purchasing antifreeze, you should consider the properties of the antifreeze you used before because it is not recommended to mix the new antifreeze with the old antifreeze so that it does not lose its protective properties. In particular, you need to be careful not to mix organic and inorganic antifreeze. You should choose the type of antifreeze recommended by your car manufacturer, including in your vehicle's owner's manual.
If you know what material the parts that make up your car's engine are made of, you can choose the antifreeze accordingly. For example, aluminum is generally used in the engines of today's vehicles. Therefore, silicate-containing hybrid type antifreeze and organic antifreeze are more preferred. The hardness of the water is also effective in the freezing degree of antifreeze used by mixing with water. If the water hardness level is low where you live, and you use your car frequently, you should know that there is no harm in choosing affordable antifreeze.
If you do not use your vehicle frequently and the water you add to the antifreeze has a high hardness level, hybrid/organic antifreeze will be a more suitable choice for you. When evaluated in terms of health, blue-colored antifreeze is known to be healthier. It is preferred in sectors where contact with food and living things is high.
