Our oceans are not only the world’s highways for raw materials, goods and people, they are vital to the health of the planet. The marine industry has a responsibility to protect them. That is why Castrol is proud to have designed stern tube and thruster lubricants, hydraulic fluids and greases to help protect both vessels and the seas. Our Bio Range lubricants have improved environmental performance in comparison to conventional mineral based oils. They address the lubricant needs of vessels at sea, and present an environmentally responsible option for your crew and marine life when it comes to spillages and disposal. OSPAR registered products Castrol BioBar, BioStat and BioTac MP are fully compliant with US 2013 VGP.
