Eni PUNICA 540 SAE 50 is a cylinder lubricant formulated to lubricate and protect pistons, piston rings, and cylinder liners from combustion byproducts in low-speed two-stroke crosshead engines using low-sulfur residual fuel. It efficiently prevents acidic corrosion on cylinder liners from low-sulfur fuels through alkaline reserve and additives that neutralize acidic combustion condensates. Its high thermal stability ensures optimum lubrication even in large bore, high pressure engines, while detergent and dispersant characteristics prevent carbon buildup that could cause ring sticking or breakage.

Eni PUNICA 540 SAE 50 is a cylinder lubricant formulated with high quality base stocks, designed to lubricate and protect the pistons, piston rings and cylinder liners from the harmful effects of combustion by products. Furthermore, its allows the formation of a suitable oil film between piston rings and cylinder liners of low speed two-stroke crosshead engines fuelled with low sulphur residual fuel.
CUSTOMER ADVANTAGES
• Eni PUNICA 540 SAE 50 is a cylinder lubricant with an alkaline reserve suitable to efficiently prevent acidic corrosion that may occur on the cylinder liners when use fuels with a low sulphur content. • The peculiar additives used in the product ensure the neutralization of the acidic condensates deriving from the combustion process, in order to prevent the corrosive phenomena. • The high thermal stability of Eni PUNICA 540 SAE 50 ensures optimum lubrication even in the largest bore engines operating at the highest mean effective pressures. • The very high detergent and dispersant characteristics of the product prevent a build-up of carbon deposits in the piston ring grooves, which can lead to ring sticking or breakage. • Eni PUNICA 540 SAE 50 is able to form a stable oil film and spread uniformly over the cylinder liner surface. These properties ensures a suitable lubrication between piston rings and cylinder liners and protects against abrasive wear, which lead to a reduction in maintenance and related costs.
