The flow properties of crude petroleum having an API gravity varying from about 6 to 12 are improved by heating the crude petroleum to a temperature of about 35° C. to 200° C. and, in the presence of a suitable viscosity reducing additive, shearing the heated crude petroleum with a high shearing force sufficient to reduce the viscosity of the crude petroleum to a range of about 250 centipoise (cP) to about 1000 cP. Suitable viscosity reducing additives include gasoline, naphtha, butanol, petroleum ether, diesel fuel, citrus oil based cleansers and degreasers, and mixtures thereof.
