Which term describes the decrease in lube oil viscosity due to dilution?

Explanation:
Viscosity drops when a lubricant is diluted, and that change is described as thinning. Thinning captures the decrease in resistance to flow as the oil becomes less viscous due to the added diluent. Dilution refers to the act of adding solvent, diluting is the process, and dilute describes the mixture or state, not the specific change in viscosity. So thinning is the best term for the viscosity reduction caused by dilution.
