Kinematic Viscosity is the resistance of a fluid to flow under gravity. The viscosity is important in determining optimum handling, storage, and operational conditions. Fuels with a very low viscosity may cause power failure due to leakage at the injector and injector pump. Kinematic viscosity is determined in accordance with ASTM D445.
ASTM D6751 Requirement: viscosity value from 1.9 to 6.0 mm2/s (cSt).
