Eni OTE 68 is a lubricant specifically designed for use in steam and gas turbine applications. It is based on high quality base stocks with specially chosen additives to provide excellent thermal and oxidation resistance, rapid air release and excellent demulsibility, which lets water separate readily from the oil. Eni OTE 68 provides outstanding performance in turbo-blowers, hydraulic machinery and air compressors with medium to high compressed air temperatures, and in all other applications requiring a high quality lubricant with good stability.
