Choose optimum performance
EALs are generally developed from three base stocks: polyglycols, natural esters and synthetic esters. Those formulated with synthetic esters combine a high viscosity index, a wide operating temperature range, good lubricity, excellent corrosion protection and high oxidative stability.
Assess the benefits
Some EALs, including ExxonMobil’s Mobil SHC™ Aware™ family of EALs, are based on synthetic esters. These high-performance lubricants can help enhance equipment reliability and component life, potentially reducing maintenance costs.
Ensure problem-free changeovers
Solvent flushing is required prior to using polyglycol-based EALs due to their incompatibility with other oil types. They are also incompatible with conventional seals and filters, making changeovers very costly. However, EALs based on synthetic esters generally have fewer issues, making changeovers simpler.
Look for endorsements
Ensure your EALs are approved by major marine OEMs. Mobil SHC™ Aware™ Series gear oils have been approved by thruster builders ZF, Nakashima, HHI Hyundai and KTE Nakashima Korea and by seal manufacturers Kemel, BVI and Hwaseung R&A. Mobil SHC™ Aware™ hydraulic oils have received approval from Eaton-Vickers and Denison for the ISO 32, 46 and 68 grades. Fincantieri Marine System Division has also endorsed ExxonMobil's EALs.
How to choose the right EAL for your vessel
More than 70,000 vessels are affected by EPA regulations requiring the use of environmentally acceptable lubricants. Is yours one of them? Download our white paper, “Environmentally acceptable lubricants: Looking beyond the label,” to learn more about:
