ExxonMobil’s guide to environmentally acceptable lubricants  

What are environmentally acceptable lubricants?

Environmentally acceptable lubricants (EALs) are lubricants that are biodegradable, minimally toxic and not bio-accumulative, according to the U.S. Environmental Protection Agency’s Vessel General Permit. The EPA requires the use of EALs for certain applications. Follow these four guidelines to choose the most effective EAL for your vessel:

    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.
