Many equipment packages in the offshore industry specify transmission type lubricants

Castrol offers a range of GL-5 specification lubricants to lubricate highly loaded gearboxes like those found in some cranes and other applications. Automatic transmission fluids are often specified for highly stressed hydraulic systems, because of their inherent high VI and stability. Applications employing wet clutches often specify tractor fluids with the appropriate anti-squawk additive systems.

Always check your equipment manual and consult with a Castrol Technical Service Engineer to choose the right product for the right application.
