Abstract
The inventions relate to light oil compositions comprising a base oil, not less than 0.01% by volume of a light oil resulting from catalytic cracking and 20 to 200 ppm (on the weight basis) of a lubricity improver, with a total sulfur content of not more than 0.05% by weight, characterized in that the light oil resulting from catalytic cracking contains (1) not less than 25% by volume of bicyclic polycyclic aromatic compounds and (2) not less than 5% by volume of tricyclic polycyclic aromatic compounds. These compositions have a sulfur content of not more than 0.05% by weight and is excellent in lubricant performance.
