OAT (Organic) vs. Conventional Coolant: Which Should You Use to Protect Your Engine?

Detailed comparison of OAT (organic) coolant and conventional coolant. Learn the pros and cons of each type, how to choose the right one, and why Gartz M77 (OAT) is the optimal choice for modern engines.

Introduction: Coolant - The "Cold Blood" Of The Engine, But Which Type Should You Choose?

The cooling system plays a vital role in maintaining a stable temperature for the engine, preventing overheating and serious damage. However, when faced with the choice of coolant, many car owners often hesitate between different types of products. In particular, the appearance ofOAT coolant (Organic Acid Technology)created a revolution, completely different from the kindTraditional coolant (IAT - Inorganic Acid Technology)already familiar.

So, what are the differences between the two, what are the pros and cons of each, and most importantly, which one should you use to best protect your engine? Gartz will help you find out in this article.

I. Traditional Coolant (IAT - Inorganic Acid Technology)

This is a coolant that has been around for a long time, easily recognizable by its dark green or blue color.

- Main ingredients:Ethylene Glycol (or Propylene Glycol) combined with inorganic anti-corrosion additives such as silicate, phosphate, borate...

- Protection mechanism:Inorganic additives create a thick coating on all metal surfaces inside the cooling system to prevent corrosion.

Advantage:

- Prices are usually cheaper.

- Provides rapid corrosion protection as soon as it is poured into the system.

Disadvantages:

- Short lifespan:Inorganic additives are quickly consumed and need to be replaced periodically every 2 years or 40,000 – 60,000 km.

- Reduced heat transfer efficiency:Thick coatings can reduce the heat transfer efficiency of the system.

- Creating residue:Silicate can settle and form sludge, causing clogging of radiators or water pumps.

- Not suitable for modern engines:Silicate additives are not compatible with aluminum and plastic parts in modern engines.

- Environmental damage:Some additives may have an environmental impact when disposed of.

II. OAT Coolant (Organic Acid Technology)

OAT coolant is a new generation, usually red, pink, orange or yellow in color.

- Main ingredients:Ethylene Glycol (or Propylene Glycol) combined with organic anti-corrosion additives (carboxylic acids).

Protection mechanism:Organic additives do not cover the entire surface but only act at the metal locations at risk of corrosion, creating an ultra-thin and localized protective film.

Outstanding advantages:

- Long Life:Organic additives are consumed very slowly, allowing a lifespan of up to 5 years or 250,000 km, saving maintenance costs and time.

- Optimal heat transfer efficiency:The thin protective film helps maintain good heat transfer capacity of the system.

- Low residue formation:Minimizes the formation of dirt, keeping the cooling system clean.

- High compatibility:Safe and compatible with most metal materials (aluminum, cast iron, copper...) and plastics and rubbers used in modern engines.

- Environmentally friendly:Does not contain toxic substances such as silicate, phosphate, nitrite, borate.

Disadvantages:

- Initial cost is higher than traditional coolant.

- Not suitable for cooling systems that are too old or have a lot of dirt (may loosen old dirt causing blockage).

What Type of Coolant Should You Use to Protect Your Engine?

The decision to choose the type of coolant depends on:

- Manufacturer's recommendation:This is the most important factor. Always check your vehicle's owner's manual or ask the manufacturer to find out what type of coolant your vehicle needs (e.g. G11, G12, G12+, G13...).

Vehicle model:

- Used cars (before 2000):Usually use IAT or HOAT.

- New cars (after 2000):Most brands recommend OAT or HOAT.

System status:For older vehicles with heavily soiled systems, conversion to OAT should be carefully considered and may require a thorough flush first.

Never mix different types of coolants.(IAT with OAT). This can cause a chemical reaction, reducing the anti-corrosion effectiveness and creating sludge, which can seriously damage the system.
