NEW EAL from Shell: Naturelle Stern Tube Fluid

Shell launched a new range of Environmentally Acceptable Lubricants (EALs), including Shell Naturelle S4 Stern Tube Fluid 100, a line designed to enable ships entering U.S. waters to comply with the revised 2013 Vessel General Permit (VGP).   Shell Naturelle S4 Stern Tube Fluid 100 is made with fully saturated ester base oil, as the oil major contends that this offers the best resistance to hydrolysis and oxidation. It is also a non-emulsifying fluid, which allows ship operators to easily drain any water from the stern tube system, preventing hydrolysis and biodegradation of the oil within the equipment.
