Shell Lubricants Power Premium product and base number monitoring lead to valuable savings at Cozumel Total reported annual customer saving US$39,000 The Energia y Agua Pura de Cozumel (Cozumel) power plant was the first to Company: Energia y Agua Para be fueled with heavy oil in Mexico and supplies its network distributors with de Cozumel electricity. Low oil performance led to poor engine cleanliness and problems Country: Mexico caused by soot and deposits. Application: Diesel engine Cozumel was trying to manage base number depletion without any guidance Saving: US$39,000 total annual from its existing lubricant supplier regarding the oil sweetening process. Sharp reported saving Key edge: Shell Argina XL 40, Shell LubeAnalyst and Shell LubeVideoCheck falls in base numbers had been experienced with two different products in its four diesel engines. An engine inspection confirmed a heavy build-up of soot and deposits: a direct result of the engine oil base number dropping below a critical level. Shell’s technical team proposed a best-in-class premium product alternative, Shell Argina XL 40 and the Shell LubeAnalyst and Shell LubeVideoCheck services to ensure base number monitoring and control. Cozumel has found that using Shell Argina XL 40 and careful monitoring means that the engines are much cleaner than before with fewer deposits in their chambers and valves. Through a combination of oil choice and a precise sweetening regime, the top-up volume dropped from125 to112 L/d with Shell Argina XL 40. This resulted in a reported annual saving of US$39,000 across the four engines, excluding the benefits from lower maintenance requirements and fewer replacement parts.

Shell Argina XL Product solution for Energia y Agua Pura de Cozumel Shell Argina XL is a multifunctional crankcase lubricant for highly rated, medium-speed diesel engines operating on residual fuel oil. Shell Argina XL is designed for conditions of very high oil stress and for improving deposit control. Improved engine reliability Extremely high detergency and dispersancy prevent sludge from forming and keep crankcases, valves, pistons lands and the critical piston undercrown area exceptionally clean. An extra-high total base number (50) means that a satisfactory equilibrium base number level can be maintained under harsh conditions, which would be impossible using an oil with a total base number of 40. Main applications Medium-speed industrial or marine propulsion and auxiliary engines burning residual fuel oils, which create conditions of very high oil stress. These conditions usually occur in newer engine designs with flame rings, especially those from Wärtsilä where oil consumption is <0.5 g/kWh where load factors are >90% where fuels with sulphur levels >3% are used in medium-speed engines burning residual fuel, which need very specialised lubricants in very high stress conditions, which are found most often in modern Wärtsilä engines in power plant or ship propulsion applications. Complementary products Lower maintenance costs Equipment Lubricants Good thermal and oxidative stability help the oil to resist thickening and result in much longer oil life and minimised wear of piston rings and cylinder liners.
