Excessive additive effect on engine oil viscosity
Original language description
The main goal of this paper is excessive additive (for oil fi lling) eff ect on engine oil dynamic viscosity. Research is focused to commercially distribute automotive engine oil with viscosity class 15W--40 designed for vans. There were prepared blendsof new and used engine oil without and with oil additive in specifi c ratio according manufacturer's recommendations. Dynamic viscosity of blends with additive was compared with pure new and pure used engine oil. The temperature dependence dynamic viscosity of samples was evaluated by using rotary viscometer with standard spindle. Concern was that the oil additive can moves engine oil of several viscosity grades up. It is able to lead to failure in the engine. Mathematical models were used for fi ttingexperimental values of dynamic viscosity. Exponential fi t function was selected, which was very accurate because the coeffi cient of determination R2 achieved high values (0.98--0.99). These models are able to predict viscosity behaviour
