Why oils of different viscosity are used...

Why oils of different viscosity are used in different seasons?

Text Solution

Verified by Experts

The temperature of surrounding air is different in different seasons. In summer the temperature of surrounding is more than that in winter. The viscosity of oil decreases with rise in temperature. Hence viscosity of oil is less in summer than in water. therefore, more viscous oils are used in summer and less viscous oils in winter.
