PETRONAS Hydraulic 68 is a premium-grade, high-performance anti-wear hydraulic fluid engineered for mobile and industrial equipment operating under normal to heavy-duty conditions
| Feature | Benefit |
| Advanced Anti-Wear Protection | Reduces component wear, extends equipment service life, and withstands heavy load stages (FZG Stage 12) |
| High Thermal & Oxidation Stability | Resists fluid breakdown under extreme heat and pressure, enabling extended oil drain intervals (3,900+ TOST hrs) |
| Rapid Air Release & Low Foaming | Prevents pump cavitation, maintains hydraulic responsiveness, and minimizes maintenance downtime |
| Superior Water Separability | Quickly sheds moisture to prevent sludge formation, rusting, and system efficiency degradation |
| Excellent Filterability | Maintains high filter efficiency without excessive pressure drop, prolonging filter life |
| Seal & Metal Compatibility | Fully compatible with yellow/white metals and standard elastomeric seals to prevent internal leaks |
