This trunk piston engine oil is specifically developed for medium-speed diesel engines operating on on distillate or residual fuels. It is engineered to deliver excellent protection in demanding environments, where engines are subjected to high mechanical loads and elevated thermal stress. The formulation provides robust acid neutralization to guard against corrosion caused by residual fuel combustion, while its strong thermal stability ensures consistent performance at prolonged high operating temperatures. In addition, it offers effective deposit control to minimize piston crown and ring groove fouling, extending engine cleanliness and efficiency. This balanced protection makes it highly suitable for marine, power generation, and industrial applications requiring reliability and long service intervals.

Application: Medium-speed trunk piston engines using heavy or hybrid fuels. – Marine propulsion or auxiliary engines operating on residual or IFO. – Designed for vessels where fuel cleanliness varies.
