BOVAS® Bomarie™ C 40, Superior Trunk Type Marine Engine Oil (TBN 40) is an advanced and superior marine engine oil designed to lubricate severe residual fuelled medium-speed diesel engines operating in marine and stationary applications on light to heavy fuel oil blends which contain high levels of sulphur. It has enough alkalinity (TBN) reserves to efficiently combat the formation of acid mists resulting from the use of very-high sulphur fuel oils.
It has excellent detergency properties, making it particularly suitable for use in supercharged engines. Its high polarity provides superior protection of engine parts from attack by moisture and salinity. It has a high level of detergency, anti-foam, anti-corrosion, anti-rust and demulsibility to ensure that engines last long and perform well under extreme conditions.
