N2 - The rheological behaviour of commercial lubrication oils used for cylinder lubrication in two-stroke marine diesel engines was studied. Also, whether the viscosity of lubrication oils is affected by different levels of alkalinity was assessed. Viscosity measurements were performed using both rotational and capillary rheometry. The viscosity measurements show that the studied lubrication oils behave as a Newtonian fluid and that the viscosities are insensitive to the level of alkalinity. Furthermore, the viscosity/temperature dependency for the lubrication oils was found to fit the Arrhenius model.
