ENI OSO AS SC
ENI OSO AS (SC) – Ashless High Quality Hydraulic Oil
ENI OSO AS is a line of ashless high quality hydraulic oils developed for use in all types of hydraulic systems and equipment, especially where products with very high filterability are required. The oils are formulated from selected paraffinic base stocks treated with anti-rust, anti-oxidant and anti-wear additives (ISO-L-HM classification).
These oils are designed for energy transmission in hydraulic systems and provide a strong lubricating film capable of withstanding heavy loads between sliding components. They offer excellent oxidation resistance and stability, minimizing sludge formation and ensuring long service life of both oil and equipment.
Key Features & Performance Benefits
- Very good anti-wear properties ensuring reliable hydraulic performance
- High oxidation resistance reduces sludge and deposit formation
- High viscosity index minimizes viscosity changes during operation
- Excellent demulsibility prevents stable emulsions in presence of water
- Suitable for very fine filtration systems (up to 3 micron)
- Strong anti-rust and anti-corrosion protection for internal components
- Low pour point allows easy start-up at low temperatures
- Maintains lubricating power even under severe operating conditions
