Properties & Performance
ENI i-SIGMA TURBO SPECIAL exhibits strong resistance to oxidation and high-temperature deterioration, helping maintain lubrication performance during prolonged heavy-duty operation.
The use of high quality base stocks and advanced additives allows longer oil drain intervals while maintaining engine cleanliness and reducing deposit formation. Its detergent-dispersant properties keep combustion by-products suspended, preventing harmful sludge and varnish build-up.
The lubricant offers excellent control against oil thickening and ensures reliable protection against wear, helping extend engine life and maintain efficiency in demanding service conditions.
