Viscosity is one of the most important properties of lubricants for the automotive engines. The way it changes depends on the temperature regime and this feature designates the temperature range under which you can apply an oil. In low temperature conditions the oil must remain of very low viscosity. And at high temperature conditions – on the contrary.  The viscosity coefficient value and the way it changes according to the temperature, determines another Our Engine Oil type.

Winter oil – with a minimum viscosity, enables easy cold start of the engine, but doesn’t provide effective lubrication at high temperature. Summer oil is not able to provide a cold start at ambient temperature below 0 degrees. On the other hand, such oil possesses excellent viscosity features in summer heat. And at last – multigrade oil has the qualities of both summer and winter oils. Their viscosity is adjusted in relation to ambient temperature. Multigrade lubricants have higher viscosity, in winter – lower. Of course, Multigrade oils are out of competition in comparison with winter and summer oils.
