CAT 3612 Gas Engines

Gas Compression Plant

Tartagal, Salta, Argentina


An Argentinian gas compression plant that operates a fleet of six CAT™ 3612 engines maintained oil drain intervals of 5,000 hours with a previous lubricant. Maintenance personnel were pleased with engine performance, and a borescope inspection found that the engine components were in good condition. Plant managers approached ExxonMobil to determine ways to further extend oil drain intervals and enhance engine performance.


ExxonMobil engineers recommended transitioning the six engines to Mobil Pegasus™ 1005, a natural gas engine oil formulated with premium base stocks and advanced additive technology, and designed to provide the highest level of protection while maintaining exceptional engine performance. Engineers also recommended implementing routine Mobil ServSM Lubricant Analysis and borescope inspections to monitor the condition of engine components and the in-service lubricant.


After transitioning to Mobil Pegasus™ 1005 natural gas engine oil, maintenance personnel successfully doubled oil drain intervals from 5,000 hours to 10,000 hours. Mobil ServSM Lubricant Analysis also revealed diminished levels of oxidation and nitration, while borescope inspections confirmed there were no deposits of varnish, lacquer or carbon residue on the various engine components. The extended oil drain intervals and reduced oil consumption generated an annual savings of US $53,700.

The product performance of Mobil Pegasus™ 1005, alongside the application expertise provided by local ExxonMobil engineering support and Mobil ServSM Lubricant Analysis, is helping to improve customer productivity potential.
