The invention concerns a petroleum product and a process for the production of a petroleum product which can form part of a blend for an internal combustion engine fuel, the process comprising a) hydrotreating a hydrocarbon feedstock at a partial pressure of hydrogen at the reactor outlet of about 0.5 MPa to about 6 MPa, b) separating a product (P) from step a) into a product (P1) with a final boiling point of about 300.degree. C. and a product (P2) with an initial boiling point greater than the final boiling point of product (P1), c) performing a liquid-liquid extraction with a solvent (S1), to produce an extract (E1) and a raffinate (R1) from product (P2), d) recovering solvent (S1) from raffinate (R1) to produce a product (Q1), depleted in solvent (S1), which has improved qualities and contains less than 500 ppm by weight of sulphur.
