Abstract

A treated oil, such as a treated heavy oil, which has a viscosity which is lower than the viscosity of the oil prior to the treatment thereof (i.e., the initial oil). The temperature at which 80 mass % of the treated oil has boiled is within 25° C. of temperature at which 80 mass % of the oil prior to the treatment thereof has boiled. Thus, the treated oil and the oil prior to the treatment thereof, have distillation curves or boiling point curves which are the same as or approximate to each other.
