Product Information
Full details
Morris Liquimatic No 6 ISO 68 Hydraulic Oil is designed for industrial and off-highway hydraulic systems requiring a high-quality, zinc-free, ashless hydraulic fluid. Its key benefit is excellent anti-wear protection and long oil life, even in demanding applications. A potential consideration is its specific ISO VG 68 viscosity grade, which may not be suitable for all systems. This oil features rapid air release, good thermal stability, and superior filterability, meeting stringent requirements for modern machinery.

FAQs
What does ISO VG 68 mean?
ISO VG 68 refers to the viscosity grade of the hydraulic oil, indicating its kinematic viscosity at 40°C. VG 68 means the oil has a viscosity in the range of 63-77 mm²/s at 40°C.
Why is being 'Zinc Free' and 'Ashless' important?
Zinc-free and ashless formulations are crucial for hydraulic systems that use certain materials like bronze or silver alloys, as traditional additives containing zinc or ash can be corrosive to them. This formulation offers broad compatibility and helps prevent deposit formation.
Can I use this oil in my car's power steering system?
While this oil is listed as compatible with power steering systems, it is essential to consult your vehicle's owner's manual to confirm if ISO VG 68 is the specified viscosity and type for your specific power steering fluid.
How does the rapid air release feature benefit my system?
Rapid air release helps to quickly eliminate trapped air bubbles within the hydraulic fluid. This reduces 'sponginess' in operation, improves system responsiveness, and prevents potential damage caused by cavitation.
What is the typical service life of this hydraulic oil?
The service life depends heavily on operating conditions, system cleanliness, and temperature. However, its 'long oil life' formulation and good thermal stability are designed to extend its operational period compared to standard hydraulic oils.
Is this oil suitable for very high-temperature applications?
The Group II base oil technology ensures reduced evaporation losses in high-temperature applications, contributing to its suitability. However, always ensure your system's operating temperatures remain within the oil's specified limits and consult equipment manufacturer recommendations.
What does 'excellent filterability' mean for my system?
Excellent filterability means the oil is less likely to form sludges or deposits that can clog fine filters. This ensures that the oil can pass through system filters smoothly, maintaining system cleanliness and preventing potential blockages that could lead to component failure.
Troubleshooting
Hydraulic system feels 'spongy' or unresponsive.
Ensure the oil has adequate time to release trapped air. Check for any air leaks in the system lines or seals. The rapid air release additive in this oil should help mitigate this over time.
Premature wear observed on hydraulic components.
Verify that the correct ISO VG 68 grade has been used and that the system is operating within its designed temperature range. Ensure no external contaminants have entered the system. If wear persists, consider a system flush and refill.
Hydraulic pump is noisy.
Check the oil level; low oil can cause pump cavitation. Ensure there are no blockages in the suction line. Verify that the oil viscosity is appropriate for the operating temperature.
Oil appears cloudy or discolored.
Cloudiness can indicate moisture contamination. Check seals and breathers for potential ingress points. Significant discoloration may indicate thermal breakdown or contamination and the oil may need to be replaced.
