Description
Application areas:
Recommended for lubrication of steam, gas & hydraulic turbines & can be used in hydraulic systems requiring very long life lubricant of outstanding properties.
Performance benefits:
- Excellent oxidation and chemical stability
- Properly balanced combination of oxidation & rust inhibitors and antifoam agents
- Excellent demulsibility and quick release of entrained air gives prolonged service life
Special Features
TURBINOL grades are premium quality lubricating oils designed to provide efficient and trouble-free service in precision industrial machinery having most exacting lubrication requirements. The excellence of TURBINOL grades is the combined result of selected stable base oils, efficient refining methods and effective additives

TURBINOL Grades are also available in non ISO VG viscosity grades like 57 and 77. While TURBINOL 57 is used in some steam and hydraulic turbines; TURBINOL 77 is used as suspension bearing oil in diesel electric locomotives. TURBINOL 77 oil is fed to the suspension bearing (journal bearing) by wick mechanism.
