Question

Why is it dangerous to not have the right grade motor oil for the climate you drive in?

Answer 1

Answer:

When temperature increases the viscosity of the oil decreases and flows too freely through the engine.

When temperature decreases the viscosity of the oil increases and does not flow fast enough through the engine.

Explanation:

When liquids flow they experience a drag in their forward movement. This drag force is called viscosity which acts in the opposite direction to the flow of the liquid.

As temperature increases the kinetic energy of the liquid particles also increases which then reduces the drag force or viscosity. Similarly as temperature decreases the kinetic energy of the liquid particles also decreases which then increases the drag force or viscosity.

Answer 2

Actually its the second and fourth one for sure! If you just put one it only gives parcel credit. ;-;
