Rock Oil introduces KOOL-GUARD P-OAT and KOOL-GUARD P-OAT -38 – two new high-performance engine coolants formulated for long-life protection in modern Asian automotive systems and light-duty trucks. Developed using phosphate-based Organic Acid Technology (P-OAT), both products offer superior heat resistance, corrosion protection, and compatibility with aluminium and other engine metals.
KOOL-GUARD P-OAT is supplied as a concentrate, requiring dilution with high-quality water before use. For added convenience, KOOL-GUARD P-OAT -38 is a pre-mixed, ready-to-use coolant, designed to deliver immediate freeze protection down to -38°C without the need for on-site mixing.
These formulations are engineered for the latest vehicles from manufacturers including Acura, Honda, Infiniti, Lexus, Nissan, Scion, Subaru, Suzuki, and Toyota. With their thermally stable additives and extremely low inhibitor depletion rates, both versions ensure extended coolant life under the most demanding thermal loads.
Key Features:
- Phosphate-based Organic Acid Technology (P-OAT) for high-temperature stability
- Long-lasting protection from corrosion, overheating, and frost
- Compatible with most MEG-based coolants – best results achieved with full system flush
- Excellent hard water stability and very low inhibitor depletion
- Silicate-, borate-, nitrite-, and amine-free formulations
- Suitable for new-generation Asian engines requiring phosphate OAT coolants
Choose the Version That Suits Your Needs:
- KOOL-GUARD P-OAT (Concentrate): Requires dilution, typically 50:50 with good-quality water
- KOOL-GUARD P-OAT -38: Pre-mixed and ready to use straight from the container
Backed by Key Industry Standards:
Both versions meet or exceed performance standards including ASTM D3306, JIS K2234:2006, SAE J1034, BS 6580:2010, and Ford WSS-M97B57-A1.
