Product Description

Shell Naturelle S4 Stern Tube Fluid 100 is an advanced, fully synthetic, readily biodegradable lubricant specifically developed for marine stern tube systems and shaft bearings. Formulated with high-performance synthetic esters and an advanced ashless additive system, it delivers exceptional protection against wear, micro-pitting, and mechanical fatigue. This ISO VG 100 fluid complies fully with the US EPA Vessel General Permit (VGP) guidelines and European Ecolabel standards for environmentally acceptable lubricants (EALs). It features outstanding emulsification characteristics, maintaining a stable protective film and reliable corrosion defense even when contaminated with up to 20% water. The fluid's high viscosity index and thermal stability resist oxidation and sludge formation, ensuring prolonged service life under demanding marine operating conditions. Furthermore, it exhibits excellent compatibility with common seal materials, helping prevent fluid leaks into the marine environment while protecting critical stern tube components.
