The viscosity of the crude oil is affected by the composition...

... As shown by the Heavy Oil sample, the LBC original viscosity correlation has limitations when it is applied to heavy oil systems. Tuning of the LBC coefficients often causes a non-monotonic relation of viscosity vs. reduced density. In such cases, it is recommended to avoid heavy tuning...
