Mixing Liquids of Certain Viscosity

I need a very small amount of 2 cSt liquid for an experiment I am doing, but I only have 5 cSt oil and water which has viscosity of 1 cSt.

Is it possible to mix the two up in the right proportion and so end up with some 2 cSt liquid (say 50 ml or something like that), it just needs to be enough to fill a teacup.
