Shell Naturelle S4 Gear Fluid 150 is an advanced, fully synthetic, readily biodegradable gear lubricant formulated for heavy-duty industrial and marine gear systems operating in environmentally sensitive areas. Based on high-quality synthetic esters and ashless anti-wear technology, it provides superior load-carrying capacity and high resistance to micropitting. This ISO VG 150 lubricant fully complies with international environmental standards, including the US EPA Vessel General Permit (VGP) and European Ecolabel requirements. It exhibits outstanding thermal and oxidation stability, preventing sludge and varnish buildup to significantly extend drain intervals. The fluid’s high viscosity index ensures optimal oil film strength across extreme operating temperatures, enabling reliable protection during high-load and continuous operations. Additionally, it offers exceptional anti-foam properties, excellent demulsibility for fast water separation, and robust corrosion defense against fresh and salt water.
