Viscosity

A measure of a fuel resistance to flow. The viscosity of a fuel is an indication of the ability to pump, treat, and atomize the fuel. The viscosity value of a fuel must always be associated with the temperature at which the viscosity was determined. The kinematic method of measuring the viscosity of a fuel is used; the kinematic centistoke (cSt = mm2/s) system of viscosity at 50°C.
