Technosynthese® engine oil for four-stroke outboard or sterndrive engines. where a NMMA FC-WTM approved lubricant is required. High temperature and high shear viscosity provides improved oil film resistance at high temperatures and limits fuel dilution during long idle periods. Ideal shear strength ensures high temperature performance of the lubricant. Outstanding anti-corrosion properties prevent corrosion caused by seawater or salt spray that may enter the cylinders through the exhaust pipe. The lubricant retains its original properties even when exposed to seawater. SAE 40 for high temperature and severe conditions in warm climates.
