Marine Gear Oil GL4/GL5 80W-90 is a heavy-duty, high-performance gear oil developed for mechanical marine gearboxes under normal to high loads. It is based on specially selected base oils combined with advanced additives that reduce wear, dampen gear noise, and provide a long-lasting lubricating film, even under demanding conditions.
The oil offers excellent corrosion protection, high resistance to aging, and a high pressure absorption capacity, which effectively protects the gear components. It complies with performance classes API GL4 and GL5 as well as viscosity SAE 80W-90, and is neutral towards common seal materials.
Suitable for outboard gears, inboard gears, and Z-drives, where operational reliability and effective gear protection are essential.
