The lubricating oils are a liquid substance, consisting of a base (mineral, synthetic or vegetable) and selected additives. They can used for lubricate internal combustion engines, so they called – engine oils. For proper functioning of the engine, lubricating oil have to fulfil basic requirements: the main function is to enable the formation of a film of oil between the moving parts which reduces friction and wear, assisting in cooling, keeping the compression ratio, reducing corrosion, filling in all micro ridges on the surface of cooperating components, sealing the combustion chamber etc. The most significant property of any lubricating oil is viscosity, which is the measure of its resistance to gradual deformation by shear stress or tensile stress. The important feature is that property of viscosity changes during the exploitation process of oil, it may increase and decrease. That is why, for engines it is important not only to choose the type of oil correctly but also to frequent monitor the viscosity. In the article, the author shows how the viscosity of marine engine oils changes after working in different types of engines. The experiments were conducted using the method of the rheometer Haake Mars III of Thermo Scientific. The samples of engine oil – Marinol RG 1240 were collected after various periods of use in three different engine types Cegielski- Sulzer.
