(Si-OAT – Silicate Enhanced Organic Acid Technology)
It contains both organic and inorganic inhibitors. It is a hybrid antifreeze with silicate additives. Suitable for classic and modern engines.
Description: Combines OAT's long-life carboxylates with IAT's fast-preserving silicates. It is used by VW (G13) and some modern European manufacturers.
The advantage: It offers immediate corrosion protection (thanks to silicate) and at the same time a long service life (thanks to OAT) in new aluminium motors.
Disadvantage: It may not be completely compatible with older OAT (G12) because it contains silicates. It may require tighter control than pure OAT.

General Instructions for Use
1. Drain the old antifreeze completely.
2. Rinse the system with clean water.
3. Fill the antifreeze product directly or by mixing it with water in the recommended ratio.
4. Start the engine and make sure there is no air left in the system.
Alerts
• Keep away from children
.• Harmful to swallow.
• Rinse with plenty of water in case of contact with eyes.
• Do not pour into the environment.
