The invention relates to producing upgraded renewable oil. Renewable crude oil is provided whose oxygen content, water content, and total acid number are within predetermined ranges. Respective fractions of the oil have boiling points below 350° C. and above 450° C. After the oil is pressurized, and hydrogen is added, the mixture is heated and contacted with a heterogeneous catalyst in a first reaction zone with weight based hourly space velocity (WHSV) of 0.1 to 1 h-1. The resultant partially hydrogenated and deoxygenated oil is further heated and contacted with a heterogeneous catalyst in a second reaction zone at WHSV of 0.1 to 1.5 h-1. Low and high boiling point liquid hydrocarbon fractions of the product of the second reaction zone are sent to third and fourth reaction zones, respectively, to be contacted with hydrogen and a heterogeneous catalyst under respective heating conditions and WHSV of 0.1 to 1 h-1.
