The low viscosity HY115 PAO products provide superior lubrication as the primary basestocks for synthetic lubricants used in passenger car engines, heavy-duty diesel engines, transmissions, gear boxes and a variety of industrial applications. Synthetic lubricants formulated with HY115 PAO may offer the following benefits:
• Extended drain intervals
• Improved fuel economy/energy efficiency
• Enhanced wear protection • Wide range of operating temperatures
