Nulon Marine 15W-40 Diesel High Protection Engine Oil is suited to inboard marine engines requiring API CI-4 15W-40 diesel engine oil. The fortified detergent and dispersant additives prevent soot and varnish build-up that is a major cause of engine wear and loss of performance. Excellent anti-oxidation and shear stable polymers ensure the oil stays “in-spec” longer, providing consistent protection during oil service intervals, while advanced corrosion inhibitors protect against harsh sea conditions and long seasonally idle periods. 

Nulon’s low-friction Advanced Additive Technology (AAT) reduces friction and engine wear, providing superior engine protection and optimum performance. This also reduces exhaust emissions, providing a cleaner environment around the boat during idling and start-up.
