A method and system for reducing viscosity in the crude oil and the empowerment of its dehydration process pass crude oil over a core that ionizes-polarizes the crude oil with an electrostatic charge. The metal bar core made of an alloy which includes, a weight of, 40-70% copper, 10-32% nickel, 15-40% zinc, 2-20% tin, and 0.05-10% silver. The metal bar core comprises a plurality of grooves, which allows crude oil to be agitated as it comes in contact with the core, activating an electrostatic charge. The electrostatic charge of the core creates a magnetic catalytic reaction that causes: (1) a molecular separation in the molecular chains within crude oil thereby lowering the viscosity and (2) stretches and twists caused by the molecular ionization-polarization of crude oil, causes that this release accordingly congenital or added water that is trapped in it, resulting in a potentiation of the dehydration of crude oil.
