1. A system that facilitates in situ determination of lubricity in a fluid, comprising:

  • a multi-element sensor positioned within a machine, the multi-element sensor obtains data regarding a plurality of parameters of a fluid, the multi-element sensor comprising two surfaces receive one or more forces, the forces causing the two surfaces to generate a frictional force between the two surfaces;

    a displacement measurement component that measures displacement relative to the two surfaces and the forces(s) causing the displacement; and

    a component that calculates lubricity of the fluid based at least in part upon the measured parameters.
