Shell aims to protect high-speed diesel engines in the fishing and tug boat segments with Shell Marine 40 engine oil. The product’s additive system controls piston deposits and helps to maintain engine cleanliness for better fuel efficiency and higher reliability, according to the company. “The high-speed engines that power tugs and fishing boats face a vastly different operational profile to a container ship or a dredger,” said Marcus Schaerer, Shell Marine global marketing manager. “We deliver lubricants that recognize and match the differing needs to help ensure that vessel engines can perform their jobs reliably and efficiently.” Web: www.shell.com/
