What cars use OAT coolant?
OAT (Organic Acid Technology) coolant is a type of engine coolant that has become increasingly common in modern vehicles. OAT coolant is designed to provide extended service life and improved corrosion protection compared to traditional inorganic acid technology (IAT) coolants. Many newer cars, trucks, and SUVs use OAT coolant as the factory-recommended fluid.
What is OAT Coolant?
OAT coolant is a silicate-free, phosphate-free, and borate-free engine coolant that uses organic acid additives to provide corrosion protection. The organic acids in OAT coolant help prevent the buildup of deposits and scale inside the cooling system. OAT coolants are designed to last longer than traditional IAT coolants, with recommended service intervals of 5-7 years or 150,000 miles.
Vehicles That Use OAT Coolant
Many modern vehicles from major automakers use OAT coolant as the factory-fill and recommended replacement fluid. Some examples include:
- Audi, Volkswagen, and Porsche vehicles (use G12++ or G13 OAT coolant)li>
- Ford, Lincoln, and Mercury vehicles (use Ford Premium Coolant or Motorcraft Orange Antifreeze)li>
- General Motors vehicles (use Dex-Cool OAT coolant)
- Honda and Acura vehicles (use Honda Long-Life Antifreeze/Coolant)
- Hyundai and Kia vehicles (use Hyundai/Kia Antifreeze/Coolant)
- Jaguar and Land Rover vehicles (use Jaguar/Land Rover Antifreeze)li>
- Mazda vehicles (use Mazda Long Life Coolant)li>
- Mercedes-Benz vehicles (use Mercedes-Benz Genuine Antifreeze/Coolant)li>
- Mitsubishi vehicles (use Mitsubishi Genuine Antifreeze)li>
- Nissan and Infiniti vehicles (use Nissan Long Life Antifreeze)li>
- Subaru vehicles (use Subaru Long Life Coolant)
- Toyota and Lexus vehicles (use Toyota Super Long Life Coolant)
It's important to always refer to the owner's manual for the specific coolant recommendation for your vehicle, as the type and color of OAT coolant can vary between manufacturers.
Can you mix OAT and regular coolant?
Never Mix OAT with Regular Coolant
Adding as little as 10% of regular coolant in an OAT system is enough to cause damage to your machine. Look for the OAT decal before adding or changing coolant to ensure you don't mix coolants and cause gelling inadvertently.
Is universal antifreeze OAT?
Because most coolants are OAT coolants, that means they are universally compatible with each other. So, despite the color or the recommendations, if a coolant says “universal,” it can be mixed or topped off with other universal coolants.
Can you mix OAT coolant with other coolant?
First, what's important to know is that many IAT and OAT coolants do not mix. In fact if they're added into a cooling system together the results can be catastrophic, creating a gelatinous substance that blocks the system and causes widespread damage to internal components.

Is OAT coolant ok for my car?
Correct. Yes. Any OAT coolant will be fine. Check your owner's manual carefully. It is a fact that there are cooling systems available in Chargers exported to the UAE that are not available in North America. Even if that weren't true, there can still be regional differences in coolant mixtures or maintenance intervals.
Are all orange coolants OAT?
Orange Coolants are also known as OAT coolants.
What vehicles use OAT coolant?
This is the type of coolant usually required for GM, Saab, and VW vehicles. OAT coolants do not have nitrites added. Contamination with nitrite – such as if you were to add the wrong type of coolant to the system – can drastically reduce the performance life of the OAT coolant.
What is the difference between OAT coolant and regular coolant?
OAT, or Organic Acid Technology, is newer and uses different ingredients to achieve the same goal. The main difference between IAT and OAT is how they protect against corrosion. IAT creates a barrier between metal surfaces, while OAT changes the pH of the coolant to make it more acidic.
Is OAT coolant the same as DexCool?
Although DexCool is not a specific formula, all three brands that have the label (Texaco Havoline, Prestone Extended Life and Zerex Extended Life) are somewhat similar. In particular, they're OAT coolants, but the similarities go beyond that basic description.
What coolant is compatible with OAT?
OAT (Orange) type coolants: GM® Dexcool®, Texaco® Havoline®, all brands made with Penray 2798 inhibitor technology, Prestone® Extended Life.
