Viscosity can delay the onset of turbulence in fluid flow; that is, it tends to stabilize the flow. Consider syrup and water, for example, and make this plausible.

It is known that the flow of fluid is laminar at low speed and becomes disordered and irregular at sufficiently high speed. If the viscous friction produced due to the viscosity of the fluid is large, then the fluid is likely to be steady and laminar.
Water has less viscosity than the syrup. So, the flow of water is likely to produce turbulent sooner than the more viscous syrup. Thus, the mixing of both the water and syrup will make a mixture such that it becomes somewhat a viscous liquid in between water and syrup. This will delay the onset of turbulent in fluid flow.
